Analytics

1. Introduction

AWS Clean Rooms is an AWS Analytics service that helps multiple organizations collaborate on data—such as advertising, measurement, and customer insights—without sharing or exposing each other’s underlying raw datasets.

In simple terms: AWS Clean Rooms lets two or more parties run approved analyses across their combined data in a “clean room,” so they can learn things like overlap and aggregated performance while keeping sensitive records private.

Technically, AWS Clean Rooms creates a controlled collaboration boundary where each participant keeps their data in their own AWS account and only shares configured access to specific tables/columns. The service enforces query controls (analysis rules), prevents disallowed queries, and returns only permitted outputs (often aggregated results) to approved recipients. It integrates with common AWS data stores and governance services so you can use existing data lake and warehouse patterns.

The problem it solves is a common one: organizations want to jointly analyze datasets (for example, a publisher and advertiser matching audiences) but cannot exchange raw user-level data due to privacy, contractual, security, or compliance constraints. AWS Clean Rooms enables privacy-enhanced collaboration with enforceable controls.

2. What is AWS Clean Rooms?

AWS Clean Rooms is an AWS service designed for privacy-enhanced data collaboration. Its official purpose is to help customers and their partners analyze and collaborate on collective datasets in AWS without sharing the underlying raw data with each other.

Core capabilities

  • Create collaborations between AWS accounts (members).
  • Register data sources (tables) as configured tables with explicit controls.
  • Enforce analysis rules that govern:
  • Allowed query types (for example, aggregation-only patterns).
  • Allowed join columns and query behavior.
  • Output restrictions and result recipients.
  • Enable members to run protected queries and receive permitted results.
  • Provide auditable governance via AWS-native logging and IAM controls.

Major components (conceptual model)

  • Collaboration: The container that defines who collaborates and the rules of engagement.
  • Membership: Each participant’s representation inside a collaboration.
  • Configured table: A member’s table registered with AWS Clean Rooms, including allowed columns and analysis rules.
  • Configured table association: The link between a configured table and a specific collaboration membership.
  • Protected query / analysis: A query executed under AWS Clean Rooms controls, producing permitted output.
  • (Optional) Templates: Some workflows support reusable query patterns/templates and controlled parameterization. Verify current template capabilities in official docs for your region and data source type.

Service type and scope

  • Service type: Managed AWS Analytics service for privacy-enhanced collaboration.
  • Scope: Regional service. You create collaborations and resources in a specific AWS Region. Participants must use compatible Regions and supported data sources. (Always verify Region availability in official docs.)
  • Account model: Collaboration members are AWS accounts. Data typically remains in each member’s account; AWS Clean Rooms enforces controls over how it can be queried.

How it fits into the AWS ecosystem

AWS Clean Rooms commonly sits on top of: – Data lake patterns: Amazon S3 + AWS Glue Data Catalog + Amazon Athena. – Data warehouse patterns: Amazon Redshift. – Governance: AWS Lake Formation (where used) + AWS IAM + AWS CloudTrail. – Security: KMS for encryption, IAM roles and policies for access control.

It is not a general data sharing service like AWS Data Exchange, and it is not a replacement for data lakes/warehouses. Instead, it provides the controlled collaboration layer and privacy guardrails for cross-party analytics.

3. Why use AWS Clean Rooms?

Business reasons

  • Partner collaboration without raw data exchange: Reduce legal and operational friction in partnerships.
  • Faster time-to-insight: Standardize collaboration patterns instead of building bespoke data-sharing pipelines.
  • Measurable outcomes: Support scenarios like campaign measurement, audience overlap, and joint analytics.

Technical reasons

  • Data stays in place: Members typically keep data in their own AWS accounts and only expose what’s needed under strict rules.
  • Query guardrails: Analysis rules can restrict query shapes and outputs (for example, aggregate-only results).
  • Leverages existing AWS analytics stack: Use Athena/Redshift and Glue/Lake Formation governance patterns.

Operational reasons

  • Repeatable collaboration constructs: Collaborations and configured tables can be managed as infrastructure and governed with change control.
  • Auditing and traceability: Activity can be logged via CloudTrail; results and access patterns can be monitored.

Security/compliance reasons

  • Minimize sensitive data exposure: Only approved columns and approved query outputs are available.
  • Separation of duties: Data owners can enforce what others can do; analysts can query only within constraints.
  • Governance alignment: Works with IAM and (where applicable) Lake Formation for permissions management.

Scalability/performance reasons

  • Scales with underlying engines: Performance and concurrency are strongly influenced by Athena/Redshift characteristics.
  • Controlled collaboration at scale: Multiple collaborations can be created for different partners and business units.

When teams should choose AWS Clean Rooms

Choose AWS Clean Rooms when: – You must collaborate with external parties on analytics but cannot share raw data. – You need enforceable controls (not just contractual agreements). – You already store data in S3/Glue/Athena and/or Redshift, and want to keep that architecture.

When teams should not choose AWS Clean Rooms

Avoid or reconsider AWS Clean Rooms when: – You actually need raw data sharing (use controlled data sharing mechanisms instead, such as governed data sharing within your org or partner data exchange patterns). – Your use case requires complex transformations, row-level outputs, or unrestricted SQL across combined data. – Your data resides outside supported sources or you cannot meet the governance prerequisites. – You need real-time transactional joins rather than analytics-oriented workloads.

4. Where is AWS Clean Rooms used?

Industries

  • Advertising and marketing measurement
  • Retail and e-commerce partnerships
  • Media and publishing
  • Financial services (privacy-constrained collaboration)
  • Healthcare and life sciences (highly controlled analytics)
  • Travel and hospitality (partner analytics with strong privacy controls)

Team types

  • Data engineering teams managing data lakes/warehouses
  • Analytics engineering and BI teams producing aggregated insights
  • Security and governance teams enforcing privacy and access controls
  • Partnerships and product analytics teams collaborating with external partners

Workloads

  • Audience overlap and reach measurement
  • Campaign measurement and attribution-style aggregates (within allowed rules)
  • Partner analytics (joint KPIs without exposing raw records)
  • Controlled data science workflows (where supported; verify current capabilities)

Architectures and deployment contexts

  • Data lake (S3 + Glue + Athena) with governance controls
  • Redshift-based analytics warehouses
  • Multi-account setups using AWS Organizations for internal clean-room collaboration
  • Cross-company collaborations with strict IAM boundaries

Production vs dev/test usage

  • Dev/test: Use small, synthetic or heavily minimized datasets; validate analysis rules; test query patterns and governance.
  • Production: Strong change control for configured tables and analysis rules, strict IAM, CloudTrail monitoring, and cost controls around query execution and underlying compute.

5. Top Use Cases and Scenarios

Below are realistic scenarios where AWS Clean Rooms is a strong fit.

1) Audience overlap between advertiser and publisher

  • Problem: Two companies want to understand how much their audiences overlap without exchanging user lists.
  • Why it fits: Join controls and aggregation-only outputs allow overlap metrics without raw identity sharing.
  • Example: A publisher and a brand compute overlap counts on hashed email to plan media spend.

2) Campaign reach and frequency measurement (aggregated)

  • Problem: Measure unique reach and frequency across multiple publishers/partners.
  • Why it fits: Controlled joins + aggregate results reduce privacy risk.
  • Example: A DSP and a publisher compute deduplicated reach by campaign and week.

3) Partner sales lift analysis (privacy-enhanced)

  • Problem: A retailer and a brand want to estimate lift from an ad campaign without sharing transaction-level data.
  • Why it fits: Enforce only aggregated outputs by cohort/time windows.
  • Example: Retailer shares configured sales table; brand shares exposure table; output is aggregated lift metrics.

4) Suppression list matching without list exchange

  • Problem: Partners want to exclude certain users (opt-out, existing customers) without exchanging raw lists.
  • Why it fits: Controlled matching and outputs can return only eligible counts/segments depending on rules.
  • Example: A bank and an insurer match hashed IDs to estimate suppressible audience size.

5) Joint KPI dashboarding for a strategic partnership

  • Problem: Build shared reporting where each party’s raw data must remain private.
  • Why it fits: Repeatable protected queries can feed downstream dashboards with approved aggregates.
  • Example: Two marketplaces share weekly aggregate conversion rates by region and product category.

6) Internal clean rooms across business units (multi-account)

  • Problem: Large enterprises with multiple accounts/business units need analytics across silos with strict boundaries.
  • Why it fits: Same service supports inter-account collaboration with enforceable controls.
  • Example: Finance and marketing accounts collaborate on aggregated churn analysis.

7) Data collaboration for regulated industries

  • Problem: Regulations prevent sharing granular records across entities.
  • Why it fits: Minimization, enforced analysis rules, and auditability help satisfy governance needs.
  • Example: A healthcare provider and research partner compute cohort aggregates.

8) Measurement with third-party datasets stored in AWS

  • Problem: You want to collaborate with a third party who already has datasets in AWS, but data cannot move.
  • Why it fits: Keep datasets in-place, collaborate via memberships and configured tables.
  • Example: A content platform collaborates with an analytics vendor for aggregated engagement insights.

9) Controlled feature engineering across parties (advanced)

  • Problem: Generate joint features without exposing raw records.
  • Why it fits: If supported in your workflow, outputs can be constrained to approved aggregates/features. Verify in official docs for supported ML/feature flows.
  • Example: Two fintechs compute aggregated behavioral features for risk trend analysis.

10) Privacy-safe experimentation analysis (A/B tests across orgs)

  • Problem: Two orgs want to measure experiment outcomes across combined events without revealing individual event logs.
  • Why it fits: Aggregation thresholds and query controls can reduce re-identification risk.
  • Example: A streaming service and device partner compute aggregated retention by experiment group.

6. Core Features

Features evolve; always validate details in the official documentation for your Region and data source type.

Collaborations and memberships

  • What it does: Creates a collaboration boundary and defines which AWS accounts are members.
  • Why it matters: Establishes the trust and administrative structure for multi-party analytics.
  • Practical benefit: Separate collaborations per partner, region, or business purpose.
  • Caveats: Collaboration setup typically requires coordination between accounts (invites/acceptance).

Configured tables (controlled exposure of data)

  • What it does: Registers a table from supported sources (commonly Glue/Athena or Redshift) with explicit column selection and rules.
  • Why it matters: Prevents accidental exposure of sensitive columns and constrains what can be queried.
  • Practical benefit: Data owners can allow only hashed join keys and non-sensitive dimensions/measures.
  • Caveats: Your underlying table permissions (Glue/Lake Formation/Redshift) must be correctly configured or queries will fail.

Analysis rules (query controls)

  • What it does: Enforces what kinds of queries can be run and what results can be returned.
  • Why it matters: The main mechanism for privacy and governance enforcement.
  • Practical benefit: Allow only aggregation outputs, restrict join columns, enforce minimum aggregation thresholds (where applicable).
  • Caveats: Rule design is critical; overly permissive rules can increase privacy risk, overly restrictive rules can block legitimate analytics.

Protected queries / controlled analysis execution

  • What it does: Executes queries under AWS Clean Rooms controls; results are released only as allowed.
  • Why it matters: Prevents “querying around” restrictions and helps enforce collaboration policies.
  • Practical benefit: Analysts can run approved SQL to produce aggregates without seeing raw data.
  • Caveats: Performance and cost depend heavily on the underlying engine (Athena/Redshift) and data scanned.

Result delivery and recipient controls

  • What it does: Controls which member(s) can receive query results.
  • Why it matters: Prevents unintended dissemination of outputs.
  • Practical benefit: Data owners can allow results to be received only by specific accounts/roles.
  • Caveats: Coordinate who should receive outputs; ensure analysts have access to the destination.

Integration with AWS governance and security services

  • What it does: Uses IAM for authorization, CloudTrail for auditing, and may integrate with Lake Formation and KMS depending on your data stores.
  • Why it matters: Enterprise-grade control and auditable operations.
  • Practical benefit: Fit into existing AWS security baselines.
  • Caveats: Misconfigured permissions are a common cause of failures.

(If applicable) Query templates / reusable analyses

  • What it does: Enables pre-approved query logic to be reused with controlled parameters (capability details vary).
  • Why it matters: Reduces the risk of ad hoc SQL and standardizes collaboration metrics.
  • Practical benefit: Faster onboarding for partners and analysts.
  • Caveats: Verify current template features, supported engines, and limitations in official docs.

(If applicable) Clean rooms for ML use cases

  • What it does: Some AWS Clean Rooms offerings include ML-oriented privacy-enhanced collaboration (often referenced as AWS Clean Rooms ML).
  • Why it matters: Expands beyond SQL aggregates to privacy-preserving modeling workflows.
  • Practical benefit: Use cases like lookalike modeling without direct data sharing (verify).
  • Caveats: ML features, availability, pricing, and constraints can differ—verify in official docs and your Region.

7. Architecture and How It Works

High-level architecture

At a high level: 1. Each party stores data in their own AWS account (commonly S3/Glue/Athena or Redshift). 2. Each party creates configured tables that expose only permitted columns and enforce analysis rules. 3. Parties join a collaboration (memberships). 4. A querying member runs protected queries referencing configured tables from members. 5. AWS Clean Rooms enforces rules and returns only allowed results to approved recipients. 6. Activity is logged (CloudTrail), and underlying engines generate their own logs/metrics.

Request/data/control flow

  • Control plane: Collaboration creation, membership management, configured table definitions, associations, and permissions. Governed by IAM and logged in CloudTrail.
  • Data plane: Protected query execution against underlying data sources. Data remains in-place; AWS Clean Rooms orchestrates execution and enforcement.
  • Result plane: Approved results are delivered to allowed recipients; avoid assuming where results persist without verifying your specific configuration and engine.

Integrations with related services

Common integrations include: – AWS Glue Data Catalog: Table definitions for Athena-backed datasets. – Amazon Athena: Serverless SQL query execution over S3 datasets. – Amazon Redshift: Data warehouse SQL execution for supported setups. – AWS Lake Formation: Centralized permissions for data lakes (where used). – AWS IAM: Access control to AWS Clean Rooms resources and underlying data stores. – AWS KMS: Encryption controls for data at rest in S3/Redshift and for any service-managed encryption where applicable. – AWS CloudTrail: Audit logs for API activity.

Dependency services

You typically need: – A supported data store (S3/Glue/Athena and/or Redshift). – Correct permissions for AWS Clean Rooms to access tables under the collaboration rules. – A logging strategy (CloudTrail and optionally CloudWatch for underlying engines).

Security/authentication model

  • Authentication and authorization are handled by AWS IAM.
  • Cross-account collaboration is done through memberships and resource sharing constructs within AWS Clean Rooms, not by sharing long-term credentials.
  • Least privilege is critical: restrict who can create collaborations, configured tables, and run protected queries.

Networking model

  • AWS Clean Rooms is an AWS-managed service accessed via AWS APIs/console.
  • Underlying queries use AWS-managed endpoints (Athena/Redshift). Networking controls depend on those services (for example, Redshift VPC networking).
  • For private connectivity requirements, evaluate AWS PrivateLink support status for AWS Clean Rooms and the underlying engines in your Region (verify in official docs).

Monitoring/logging/governance considerations

  • CloudTrail: Track who created collaborations, configured tables, ran protected queries, and changed policies.
  • Athena/Redshift logs: Performance, query execution, and failures.
  • Cost monitoring: Use Cost Explorer and cost allocation tags; monitor Athena scanned bytes and Redshift usage.

8. Prerequisites

Accounts and collaboration requirements

  • Two AWS accounts are strongly recommended for a realistic AWS Clean Rooms lab:
  • Account A: “Publisher” (data owner)
  • Account B: “Advertiser” (data owner + querying member)
  • If you only have one account, you can still learn concepts, but many collaboration flows are inherently cross-account.

Permissions / IAM

You need IAM permissions to: – Create and manage AWS Clean Rooms resources (collaborations, memberships, configured tables, associations, protected queries). – Access underlying data sources (Glue/Athena/S3 and/or Redshift). – Create IAM roles and allow service-linked roles if prompted.

A practical approach: – Create an admin-like lab role/user in each account for setup. – Later, split into least-privilege roles: CleanRoomsAdmin, CleanRoomsAnalyst, DataOwnerAdmin.

Exact IAM actions change over time. Use the AWS managed policies (if provided) or build least-privilege policies from the official IAM documentation for AWS Clean Rooms. Verify in official docs.

Billing requirements

  • A valid payment method on both AWS accounts.
  • Cost controls: AWS Budgets alarms for Athena scans and any warehouse usage.

CLI/SDK/tools

  • AWS Console (primary for beginners).
  • Optional: AWS CLI v2 configured in both accounts.
  • Optional: Athena query editor in the console.

Region availability

  • Choose a Region where AWS Clean Rooms is available.
  • Ensure Athena/Glue (and Redshift if used) are available in the same Region.
  • Verify current Region list in official docs:
  • https://docs.aws.amazon.com/clean-rooms/

Quotas/limits

  • AWS Clean Rooms has service quotas (for example, number of collaborations, configured tables, associations, and query concurrency).
  • Check Service Quotas in the AWS console for “AWS Clean Rooms” and verify defaults/adjustments.

Prerequisite services

For this tutorial lab, you’ll use: – Amazon S3 (store small CSV files) – AWS Glue Data Catalog (table definitions) – Amazon Athena (create tables and run SQL over S3)

9. Pricing / Cost

AWS Clean Rooms pricing is usage-based, and your total cost is usually a combination of: 1. AWS Clean Rooms charges (for collaboration and/or query execution depending on the current model) 2. Underlying analytics engine charges (Athena and/or Redshift) 3. Storage and requests (S3 storage, PUT/GET requests) 4. Data governance (Lake Formation itself does not usually add direct cost, but operations overhead exists) 5. Logging (CloudTrail, Athena query logs, S3 for log storage)

Because pricing can change and is Region-dependent, use the official pricing page: – AWS Clean Rooms Pricing: https://aws.amazon.com/clean-rooms/pricing/ – AWS Pricing Calculator: https://calculator.aws/

Pricing dimensions (what to expect)

Verify current dimensions on the pricing page, but commonly relevant dimensions include: – Protected query execution (per query, per compute/time, or per unit of processing—varies by model) – Collaboration-related charges (if any) – Additional features (for example, ML-oriented workflows) may have separate pricing

Free tier

AWS Clean Rooms does not typically advertise a broad free tier in the way some services do. Always confirm on the pricing page for your Region.

Cost drivers

  • Number of protected queries (and their complexity)
  • Data scanned by Athena (major driver for S3-based datasets)
  • Redshift usage (cluster size, concurrency, serverless capacity, etc.)
  • Data layout (partitioning, columnar formats like Parquet can drastically reduce Athena scan costs)
  • Iteration (analysts repeatedly running similar queries)
  • Cross-Region or egress (less common if all parties operate in the same Region, but verify)

Hidden or indirect costs

  • Storing collaboration datasets longer than needed (S3 lifecycle policies help)
  • Re-scanning unoptimized CSVs in Athena instead of Parquet/partitioned data
  • CloudTrail log retention and storage
  • Engineering time to design and maintain analysis rules and governance

Network/data transfer implications

  • Data typically remains in-place within accounts; however:
  • If results are exported to other systems or Regions, standard AWS data transfer charges can apply.
  • Redshift in a VPC and related data movement can incur additional costs (verify for your architecture).

How to optimize cost

  • Start with tiny datasets for labs.
  • Use Athena with Parquet and partitions in production.
  • Restrict who can run queries and how often (IAM + operational process).
  • Use AWS Budgets + Cost Anomaly Detection.
  • Implement query templates/standard analyses where supported to reduce experimentation scans.

Example low-cost starter estimate (no fabricated numbers)

A small lab with: – Two tiny CSV tables (a few KB to MB), – A handful of protected queries, – Minimal logging retention,

…should cost only a small amount, mostly driven by Athena query scans and any AWS Clean Rooms per-query charges (if applicable). The exact cost depends on your Region and current pricing. Check the AWS Pricing Calculator before running repeated queries.

Example production cost considerations

In production, costs often come from: – High query volume (multiple partners, frequent reporting cadence) – Large datasets with repeated scans – Redshift warehouse costs if used – Data engineering to optimize storage formats and partitions – Governance overhead and audits

10. Step-by-Step Hands-On Tutorial

This lab demonstrates a realistic, low-cost workflow using two AWS accounts, S3 + Glue + Athena, and AWS Clean Rooms to compute an audience overlap metric using hashed identifiers and aggregation-only outputs.

Objective

Create an AWS Clean Rooms collaboration between two AWS accounts and run a protected query that returns an aggregated overlap count—without either party sharing raw rows.

Lab Overview

  • Account A (“Publisher”) creates a small dataset of hashed user IDs (plus a dimension).
  • Account B (“Advertiser”) creates another small dataset of hashed user IDs (plus a dimension).
  • Both create Athena tables over their CSVs.
  • Account A creates an AWS Clean Rooms collaboration and invites Account B.
  • Each account creates a configured table and associates it with the collaboration membership.
  • Account B runs a protected query to count the overlap by joining on the hashed ID.
  • You validate results and then clean up resources.

Notes: – This lab uses synthetic data. Do not use real PII. – UI labels and exact steps can change. If your console differs, follow the same concepts and verify in official docs.

Step 1: Choose a Region and prepare two AWS accounts

  1. Pick an AWS Region where AWS Clean Rooms is available (for example, us-east-1 or another supported Region).
  2. Ensure you can sign in to Account A and Account B with permissions to manage: – S3, Glue, Athena – AWS Clean Rooms – IAM (at least to create service-linked roles if prompted)

Expected outcome – You have two accounts ready in the same Region.

Verification – In each account, open the AWS Clean Rooms console and confirm it loads: – https://console.aws.amazon.com/cleanrooms/

Step 2: Create a small dataset in Account A (Publisher)

2.1 Create an S3 bucket

In Account A: 1. Open Amazon S3 console. 2. Create a bucket such as: – cleanrooms-lab-publisher-<unique-suffix> 3. Keep default settings, but ensure Block Public Access remains enabled.

2.2 Upload a CSV file

Create a file named publisher_audience.csv with the following content:

user_id_hash,segment
aaa111,news
bbb222,sports
ccc333,news
ddd444,finance
eee555,sports

Upload it to: – s3://cleanrooms-lab-publisher-<suffix>/data/publisher_audience.csv

Expected outcome – Account A has a bucket with a CSV dataset.

Verification – In S3, you can see the file and its size.

Step 3: Create a small dataset in Account B (Advertiser)

Repeat the process in Account B:

3.1 Create an S3 bucket

  • cleanrooms-lab-advertiser-<unique-suffix>

3.2 Upload a CSV file

Create advertiser_audience.csv:

user_id_hash,campaign
bbb222,spring_launch
ccc333,spring_launch
xxx999,brand_awareness
yyy888,spring_launch

Upload to: – s3://cleanrooms-lab-advertiser-<suffix>/data/advertiser_audience.csv

Expected outcome – Account B has its own dataset.

Step 4: Create Athena tables (Account A and Account B)

You will create an Athena database and external table in each account.

Athena requires an S3 location for query results. If you haven’t used Athena before, the console may prompt you to configure a query result location (for example, s3://<bucket>/athena-results/).

4.1 Account A: Create database and table

In Account A, open Athena Query Editor and run:

CREATE DATABASE IF NOT EXISTS cleanrooms_lab;

CREATE EXTERNAL TABLE IF NOT EXISTS cleanrooms_lab.publisher_audience (
  user_id_hash string,
  segment string
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
  'separatorChar' = ',',
  'quoteChar'     = '"',
  'escapeChar'    = '\\'
)
LOCATION 's3://cleanrooms-lab-publisher-<suffix>/data/'
TBLPROPERTIES ('skip.header.line.count'='1');

Test it:

SELECT * FROM cleanrooms_lab.publisher_audience LIMIT 10;

4.2 Account B: Create database and table

In Account B, run:

CREATE DATABASE IF NOT EXISTS cleanrooms_lab;

CREATE EXTERNAL TABLE IF NOT EXISTS cleanrooms_lab.advertiser_audience (
  user_id_hash string,
  campaign string
)
ROW FORMAT SERDE 'org.apache.hadoop.hive.serde2.OpenCSVSerde'
WITH SERDEPROPERTIES (
  'separatorChar' = ',',
  'quoteChar'     = '"',
  'escapeChar'    = '\\'
)
LOCATION 's3://cleanrooms-lab-advertiser-<suffix>/data/'
TBLPROPERTIES ('skip.header.line.count'='1');

Test it:

SELECT * FROM cleanrooms_lab.advertiser_audience LIMIT 10;

Expected outcome – Each account can query its own dataset in Athena.

Verification – You see rows from each table in Athena query results.

Common errors – If Athena can’t read the CSV, confirm: – Correct S3 path ends with /data/ – File is in that prefix – Header skip property is set – Your Athena query results bucket is configured

Step 5: Create an AWS Clean Rooms collaboration (Account A invites Account B)

In Account A: 1. Open AWS Clean Rooms console. 2. Create a Collaboration. 3. Enter: – Name: cleanrooms-lab-collab – Description: optional 4. Add member: – Member AWS Account ID: Account B’s ID 5. Choose collaboration settings: – Select the appropriate query/analysis mode for your use case. – For this lab, prefer a configuration that supports SQL analysis and aggregation-only outcomes. (Exact options vary—follow the console’s guidance and verify in docs.) 6. Create the collaboration.

In Account B: 1. Open AWS Clean Rooms console. 2. Accept the invitation and create a Membership if prompted.

Expected outcome – A collaboration exists in Account A. – Account B is an accepted member with its own membership.

Verification – In both accounts, you can open the collaboration and see both members listed.

Step 6: Create configured tables (each account)

Now each member registers their Athena/Glue table as a configured table with strict controls.

6.1 Account A: Create configured table for publisher data

In Account A: 1. Go to Configured tables in AWS Clean Rooms. 2. Create configured table: – Data source: choose Glue Data Catalog / Athena table (wording varies) – Database: cleanrooms_lab – Table: publisher_audience 3. Select columns to include: – user_id_hash – segment 4. Configure analysis rules: – Restrict to aggregation results. – Allow joining only on user_id_hash. – Consider enabling an aggregation threshold/minimum output rule if available in your chosen mode. 5. Create the configured table.

6.2 Account B: Create configured table for advertiser data

In Account B, repeat: – Database: cleanrooms_lab – Table: advertiser_audience – Columns: user_id_hash, campaign – Analysis rules: – Aggregation-only – Join on user_id_hash

Expected outcome – Each account has a configured table with enforced rules.

Verification – In each account, the configured table shows the selected columns and analysis rule configuration.

Common errors – If you cannot see your Athena table in AWS Clean Rooms, verify: – The table is in the same Region. – Glue catalog contains the table. – Permissions allow AWS Clean Rooms to reference it (verify required IAM/Lake Formation permissions in official docs).

Step 7: Associate configured tables with the collaboration (both accounts)

A configured table must be associated with a collaboration membership before it can be used in that collaboration.

7.1 Account A: Associate publisher configured table

In Account A: 1. Open the publisher configured table. 2. Choose Associate with collaboration. 3. Select the membership for cleanrooms-lab-collab. 4. Create the association.

7.2 Account B: Associate advertiser configured table

In Account B: – Associate the advertiser configured table with the same collaboration membership.

Expected outcome – Each membership has configured table associations available for protected queries.

Verification – In the collaboration view (or membership view), you can see both associated configured tables.

Step 8: Run a protected query (Account B as the querying member)

In Account B (Advertiser), run a query that computes overlap counts by campaign and publisher segment.

  1. In AWS Clean Rooms console, go to the collaboration and find the analysis / queries area (label varies).
  2. Choose to create/run a protected query referencing both configured tables.
  3. Use SQL similar to:
SELECT
  a.campaign,
  p.segment,
  COUNT(*) AS overlap_count
FROM
  advertiser_audience a
JOIN
  publisher_audience p
ON
  a.user_id_hash = p.user_id_hash
GROUP BY
  1, 2
ORDER BY
  overlap_count DESC;

Important: – In AWS Clean Rooms, table references are often based on the collaboration’s configured table names/aliases, not raw Glue table names. Use the console’s query editor/table picker to insert the correct references.

Expected outcome – The query succeeds and returns aggregated counts (no raw rows). – Based on our synthetic data, the overlap users are bbb222 and ccc333, so you should see overlap counts for the joined combinations (campaign × segment) that correspond to those IDs.

Verification – You see a small result set with counts (for example, spring_launch overlapping with sports and news depending on which IDs map to which segment).

Validation

Use these checks to confirm the clean room behavior: 1. Attempt a disallowed query (for example, selecting raw user_id_hash values).
– It should be blocked by analysis rules. 2. Confirm columns are restricted: – Columns not included in configured tables should not be selectable. 3. Confirm auditing: – In CloudTrail (each account), search for AWS Clean Rooms events around collaboration and query execution.

Troubleshooting

Common issues and fixes:

  1. “Access denied” when creating configured table or running query – Verify IAM permissions for AWS Clean Rooms APIs. – If using Lake Formation, verify Lake Formation grants for the table/location. – Verify S3 permissions for Athena to read the data and write query results.

  2. Athena table not visible in AWS Clean Rooms – Confirm the Glue Data Catalog table exists in the same Region. – Confirm you’re using the same AWS Region in AWS Clean Rooms console. – Confirm the table is supported (some table types or formats may not be supported).

  3. Query fails due to join restrictions – Ensure both configured tables allow joins on the same join key (user_id_hash). – Ensure your SQL matches allowed query patterns (aggregation-only, group-by required, etc.).

  4. Unexpected high cost – CSV scanning can be inefficient at scale; in production switch to Parquet + partitioning. – Reduce repeated queries; standardize templates/approved queries where possible. – Set budgets and alerts.

Cleanup

Clean up to avoid ongoing costs:

In both accounts: 1. AWS Clean Rooms: – Delete protected query artifacts/history if applicable (where supported). – Disassociate configured tables from the collaboration. – Delete configured tables. – In Account B, delete the membership (if console supports it). – In Account A, delete the collaboration (must remove members first). 2. Athena/Glue: – Drop tables: sql DROP TABLE IF EXISTS cleanrooms_lab.publisher_audience; DROP TABLE IF EXISTS cleanrooms_lab.advertiser_audience; DROP DATABASE IF EXISTS cleanrooms_lab; 3. S3: – Empty and delete buckets created for the lab (including Athena results buckets/prefixes).

11. Best Practices

Architecture best practices

  • Prefer S3 + Parquet + partitioning for large datasets queried via Athena to reduce scans and cost.
  • Use separate collaborations per partner to isolate governance and lifecycle management.
  • Model your collaboration like a product:
  • clear owners,
  • versioned analysis rules,
  • documented approved queries.

IAM/security best practices

  • Apply least privilege:
  • Separate roles for collaboration admin vs analyst.
  • Restrict who can create configured tables and who can run protected queries.
  • Enforce MFA and use federation (IAM Identity Center) for human access.
  • Use resource-level permissions where supported.
  • Use service control policies (SCPs) in AWS Organizations to prevent unapproved Regions/actions.

Cost best practices

  • Monitor Athena scanned bytes and query frequency.
  • Standardize query patterns to avoid exploratory “scan storms.”
  • Use AWS Budgets and anomaly detection.
  • Apply S3 lifecycle policies for logs and intermediate outputs.

Performance best practices

  • Optimize data layout:
  • Use columnar formats (Parquet/ORC) and compression.
  • Partition large fact tables by date/campaign/region where appropriate.
  • Limit join cardinality; prefer cohort-based aggregations.
  • For Redshift-backed data, ensure proper distribution/sort keys and concurrency configuration (as applicable).

Reliability best practices

  • Treat configured table definitions and analysis rules as code:
  • use change control,
  • peer reviews,
  • test collaboration in non-prod.
  • Keep a rollback strategy if rule changes break partner workflows.

Operations best practices

  • Implement runbooks:
  • onboarding/offboarding partners,
  • rotating join keys if needed,
  • responding to denied queries.
  • Use CloudTrail for audits and incident response.
  • Tag AWS Clean Rooms resources for cost allocation and ownership:
  • Owner, Environment, Partner, DataDomain, CostCenter.

Governance/tagging/naming best practices

  • Naming conventions:
  • cr-<env>-<partner>-<purpose>
  • ct-<domain>-<table>-v<version>
  • Document:
  • join key definitions (hashing, salt strategy, canonicalization),
  • approved dimensions/measures,
  • minimum aggregation thresholds and privacy rationale.

12. Security Considerations

Identity and access model

  • AWS Clean Rooms uses IAM for all authorization.
  • Use separate IAM roles:
  • CleanRoomsAdmin: create collaborations/configured tables, manage members.
  • CleanRoomsAnalyst: run protected queries, view allowed results.
  • Keep permissions scoped to specific resources (collaborations/configured tables) when possible.

Encryption

  • S3: Use SSE-KMS for sensitive datasets.
  • Athena: Encrypt query results in S3 (SSE-S3 or SSE-KMS).
  • Redshift: Use encryption at rest and secure connectivity.
  • For AWS Clean Rooms service-managed encryption behaviors, verify in official docs.

Network exposure

  • Keep buckets private, block public access, and restrict access with IAM and bucket policies.
  • If using Redshift, restrict network paths (VPC security groups, private subnets) and control who can connect.
  • Evaluate PrivateLink availability for your design (verify in docs).

Secrets handling

  • Avoid embedding sensitive keys in code or queries.
  • If you need salts/pepper for hashing join keys:
  • store them in AWS Secrets Manager,
  • restrict access,
  • rotate periodically,
  • document canonicalization steps.

Audit/logging

  • Enable CloudTrail in all participating accounts.
  • Store CloudTrail logs in a centralized log archive account if using AWS Organizations.
  • Monitor for:
  • collaboration changes,
  • configured table changes,
  • unusual query volume.

Compliance considerations

AWS Clean Rooms can support privacy programs, but it does not automatically make a workflow compliant. You still need: – Data processing agreements with partners. – Data minimization policies. – Privacy impact assessments. – Retention and deletion policies.

Common security mistakes

  • Allowing too many columns (especially quasi-identifiers) into configured tables.
  • Allowing flexible queries that can be combined to infer individual records (“difference attacks”).
  • Failing to enforce minimum aggregation thresholds where appropriate.
  • Not restricting who can run protected queries.
  • Using real PII in collaboration join keys without appropriate hashing and governance.

Secure deployment recommendations

  • Use strong join key hygiene:
  • canonicalize inputs (lowercase emails, trim spaces),
  • hash using approved algorithms,
  • avoid sharing raw identifiers.
  • Implement privacy review and approve analysis rules centrally.
  • Start with strict aggregation-only rules and relax only if business-justified.

13. Limitations and Gotchas

Always verify current limits and feature support in the official documentation.

  • Region availability: Not all Regions support AWS Clean Rooms.
  • Data source support: Supported sources and table types are limited (commonly Athena/Glue and Redshift). Unsupported formats or catalogs can block adoption.
  • Permissions complexity: Lake Formation and cross-account governance can be non-trivial; misconfigurations are common.
  • Cost surprises:
  • Athena scans large datasets if data is not partitioned/columnar.
  • Re-running queries frequently can multiply costs.
  • Query restrictions:
  • Analysis rules may require aggregations and disallow raw selects.
  • Join restrictions can require specific keys and patterns.
  • Privacy pitfalls:
  • Too-granular group-bys can create tiny groups that risk re-identification.
  • Multiple queries can be combined to infer hidden data if rules are not designed carefully.
  • Operational lifecycle:
  • Partner onboarding/offboarding must be handled carefully to ensure access is revoked.
  • Rule changes can break partner workflows; version and communicate changes.
  • Underlying engine behavior:
  • Performance depends on Athena/Redshift tuning and data layout.
  • Query failures often originate in the underlying engine, not AWS Clean Rooms itself.

14. Comparison with Alternatives

AWS Clean Rooms is one option in a broader space of privacy-enhanced collaboration, governed sharing, and analytics platforms.

Comparison table

Option Best For Strengths Weaknesses When to Choose
AWS Clean Rooms Privacy-enhanced collaboration across AWS accounts Enforceable query controls, data stays in place, AWS-native IAM/CloudTrail integration Requires careful rule design; limited to supported sources and patterns; cross-account setup complexity You and partners are on AWS and need controlled joint analytics without raw data exchange
AWS Lake Formation (sharing/governance) Governing data access within/among AWS accounts Fine-grained permissions for data lakes; integrates with Glue/Athena/Redshift Not a clean room by itself; can still expose raw data if granted Internal sharing across accounts where clean-room-style controls aren’t required
AWS Data Exchange Publishing/subscribing to datasets Simplifies data product distribution Data is delivered/shared; not designed to prevent raw access once subscribed You intend to distribute datasets (or subscribe) rather than do joint privacy-enhanced analysis
Amazon Athena alone Querying data in S3 Serverless, simple No partner clean-room governance layer by itself Single-organization analytics where cross-party restrictions aren’t needed
Amazon Redshift data sharing Sharing within Redshift ecosystems (often within org or trusted partners) Fast, warehouse-native sharing for some patterns Not a clean room; doesn’t inherently enforce clean-room-style query controls You need fast warehouse sharing in a trusted boundary (verify fit for partner scenarios)
Snowflake Data Clean Rooms (Snowflake) Organizations standardized on Snowflake Strong ecosystem for data collaboration Different platform; cost and lock-in; requires Snowflake adoption Partners already use Snowflake and want clean-room features there
Databricks clean room patterns Lakehouse-based collaboration Flexible compute and ML Often more DIY governance; partner setup varies You’re already on Databricks and need custom collaboration patterns
Open-source + custom governance Highly customized requirements Maximum control and portability High engineering effort; hard to enforce privacy safely; auditing complexity You have strong in-house expertise and a need not met by managed clean room services

15. Real-World Example

Enterprise example: Retailer + CPG brand measurement collaboration

  • Problem: A large retailer and a consumer packaged goods (CPG) brand want campaign measurement: overlap of ad exposure with purchases and aggregated lift by region and week—without sharing transaction-level records.
  • Proposed architecture:
  • Retailer keeps transaction fact tables in S3/Glue and/or Redshift.
  • Brand keeps exposure logs and campaign metadata in its own AWS account.
  • Both create AWS Clean Rooms configured tables:
    • Join on hashed customer ID
    • Aggregation-only analysis rules
    • Minimum output thresholds for privacy
  • Brand runs protected queries that return weekly aggregated lift metrics.
  • Outputs flow to the brand’s BI environment; retailer receives only the agreed metrics if configured.
  • Why AWS Clean Rooms was chosen:
  • Enforceable restrictions beyond contractual agreements
  • Data stays in each party’s AWS account
  • IAM + CloudTrail supports audit requirements
  • Expected outcomes:
  • Faster campaign reporting cycles
  • Reduced compliance risk from raw data exchange
  • Repeatable measurement framework for multiple brands

Startup/small-team example: Two SaaS companies doing co-marketing analytics

  • Problem: Two SaaS companies run a co-marketing webinar series and want to understand audience overlap and downstream conversion—without exchanging customer lists.
  • Proposed architecture:
  • Each company stores webinar registrations and trial signups in S3 as small Parquet tables.
  • AWS Clean Rooms collaboration with strict aggregation-only rules.
  • Weekly protected query returns overlap counts and aggregate conversion rates by channel.
  • Why AWS Clean Rooms was chosen:
  • Minimal infrastructure to stand up compared to building a custom secure sharing pipeline
  • Strong controls reduce legal risk
  • Expected outcomes:
  • Better partner targeting and spend decisions
  • Reduced engineering time spent on bespoke data exchange processes

16. FAQ

  1. Does AWS Clean Rooms move my data into another account?
    Typically, data stays in the owning account and is accessed under configured rules for protected queries. Confirm exact behavior for your data source and configuration in official docs.

  2. Can participants see each other’s raw rows?
    In clean-room patterns, analysis rules commonly restrict outputs to aggregates and prevent raw row access. Your configured rules determine what’s possible.

  3. Do I need two AWS accounts?
    For real collaborations, yes—members are AWS accounts. For learning, you can read docs and design rules, but executing a full collaboration is best with two accounts.

  4. What data sources are supported?
    Commonly Athena/Glue and Redshift are supported. Support can vary by Region and feature set—verify in official docs.

  5. Can I use AWS Clean Rooms for PII matching?
    You should avoid sharing raw PII. Use hashed/pseudonymized identifiers and follow your compliance program. AWS Clean Rooms helps enforce controls but doesn’t replace privacy engineering.

  6. How do analysis rules prevent privacy leaks?
    They can restrict query shapes (for example, aggregation-only), join keys, and outputs. Proper rule design is essential to prevent inference attacks.

  7. Is AWS Clean Rooms a replacement for a data lake or data warehouse?
    No. It sits on top of your lake/warehouse to enable privacy-enhanced collaboration.

  8. How is access controlled?
    With IAM at the API level plus configured tables and analysis rules at the collaboration level, and underlying data permissions (S3/Glue/Lake Formation/Redshift).

  9. Can I control who receives results?
    Yes, result recipient controls are part of the collaboration governance model (exact options depend on configuration).

  10. How do I audit activity?
    Use CloudTrail for AWS Clean Rooms API calls and underlying engine logs (Athena/Redshift) for query execution details.

  11. Will Athena costs dominate my bill?
    Often yes for S3-backed datasets if data is large and unoptimized. Use Parquet, partitions, and strict query patterns.

  12. Can I run BI dashboards off AWS Clean Rooms outputs?
    Yes, if outputs are delivered in a way your BI system can read (for example, stored query results or downstream tables). Exact patterns depend on configuration—verify in docs and your data platform.

  13. What’s the biggest implementation risk?
    Misconfigured permissions and poorly designed analysis rules. Treat rule design as a security/privacy engineering task, not just a SQL task.

  14. How do I onboard a new partner safely?
    Create a new collaboration, start with minimal columns and strict rules, validate with synthetic data, then expand carefully with approvals and audits.

  15. Is AWS Clean Rooms suitable for real-time use cases?
    It’s primarily designed for analytics-style collaboration. For real-time transactional requirements, you may need a different architecture.

  16. Can I collaborate across Regions?
    Collaborations are regional constructs. Cross-Region patterns may require replication or separate collaborations—verify supported patterns and implications.

  17. How do I revoke a partner’s access?
    Offboard by removing memberships/associations, deleting collaborations as needed, and ensuring underlying data permissions remain private.

23. Summary

AWS Clean Rooms is an AWS Analytics service for privacy-enhanced data collaboration across AWS accounts. It enables partners (or internal business units) to run approved analyses across combined datasets while keeping each party’s raw data protected through configured tables, analysis rules, and controlled result delivery.

It fits best when you need enforceable governance—beyond simple data sharing—while leveraging existing AWS data platforms such as S3 + Glue + Athena and Amazon Redshift. The key cost factors are typically query execution (AWS Clean Rooms pricing model plus underlying Athena/Redshift costs) and data scanned, while key security factors include least-privilege IAM, careful analysis rule design, encryption, and strong auditing via CloudTrail.

Use AWS Clean Rooms when you must collaborate on analytics without exchanging raw datasets; avoid it when you need unrestricted SQL or raw data sharing. Next, deepen your skills by optimizing data formats (Parquet/partitioning), formalizing governance with Lake Formation, and implementing repeatable partner onboarding with strict rule reviews and cost controls.
