Oracle Cloud FastConnect Tutorial: Architecture, Pricing, Use Cases, and Hands-On Guide for Networking, Edge, and Connectivity

1. Introduction

What this service is: FastConnect is Oracle Cloud’s dedicated, private connectivity service that links your on-premises network (or colocation) to Oracle Cloud using a private circuit rather than the public internet.
One-paragraph simple explanation: If you need a more predictable, lower-latency, and more reliable network path into Oracle Cloud than an internet-based VPN, FastConnect provides a private connection with consistent bandwidth and enterprise routing.
One-paragraph technical explanation: FastConnect delivers private Layer 2 connectivity (through Oracle-provided cross-connects in supported locations or through approved partners). You establish BGP sessions on virtual circuits that terminate on an Oracle Dynamic Routing Gateway (DRG) to reach VCNs privately, or (with a different virtual circuit type) to access Oracle public services over private connectivity.
What problem it solves: It reduces dependency on internet variability for hybrid cloud connectivity, improves throughput and latency consistency, simplifies predictable network design for hybrid architectures, and can help meet security and compliance requirements where private connectivity is preferred or required.

FastConnect is an active, current Oracle Cloud service name (not a renamed or retired product). If you see older references to “OCI Classic” networking patterns, treat them as legacy; modern OCI networking typically centers on VCNs and the DRG.

2. What is FastConnect?

Official purpose (in practical terms):
FastConnect is designed to provide dedicated private network connectivity between your network and Oracle Cloud Infrastructure (OCI) resources, avoiding the public internet.

Core capabilities

Private connectivity to OCI networks (VCNs) through a DRG using private virtual circuits
Private connectivity to Oracle public services (for example, public endpoints) using public virtual circuits (requirements differ from private virtual circuits—verify exact prerequisites in official docs)
Dynamic routing with BGP, enabling route advertisement and failover behavior aligned with enterprise network practices
Redundancy patterns (multiple physical connections / multiple virtual circuits) for high availability designs
Partner-based connectivity options for customers who don’t want to build cross-connects directly in an Oracle FastConnect location

Major components (you will see these in OCI)

Component	What it is	Why it matters
FastConnect Location	A physical site (Oracle or partner) where connectivity is established	Determines where the circuit terminates and what providers are available
Cross-connect / Cross-connect Group	Dedicated physical connections and a logical grouping for redundancy	Common for “dedicated” connectivity models
FastConnect Partner	Approved provider that delivers connectivity to Oracle	Often simplifies procurement and speeds provisioning
Virtual Circuit (VC)	Logical connection that runs over a physical link/partner link	Where you configure bandwidth, BGP, and circuit type (private/public)
DRG (Dynamic Routing Gateway)	Regional gateway that connects VCNs to on-prem via FastConnect (and VPN)	The primary attachment point for private connectivity
VCN Route Tables / DRG Route Tables	Routing policies on VCN subnets and DRG attachments	Controls traffic paths and segmentation
Customer Edge (CE) Router	Your router/firewall device on-prem or in colocation	Runs BGP and exchanges routes with Oracle

Service type

Service category: Networking, Edge, and Connectivity (Oracle Cloud)
Type: Hybrid connectivity / dedicated private network access service
Scope: Regional in the sense that virtual circuits and DRGs are associated to regions; connectivity is built to a specific region/DRG. For multi-region connectivity you typically combine FastConnect with multi-region routing patterns (for example, DRG connectivity and inter-region designs). Verify the latest OCI multi-region networking guidance in official architecture docs.

How FastConnect fits into the Oracle Cloud ecosystem

FastConnect is rarely used alone. It is typically part of:

Hybrid cloud patterns: on-prem ↔ OCI workloads
Landing zones: hub-and-spoke VCNs, transit VCN, shared services, centralized inspection
Disaster recovery: replicate data to OCI, run warm standby, or fail over applications
Data-intensive pipelines: stable throughput into OCI storage/analytics platforms

3. Why use FastConnect?

Business reasons

Predictable connectivity supports business-critical applications that can’t tolerate variable network paths.
Hybrid operating models become simpler when cloud resources can be treated like an extension of the corporate network.
Procurement options (direct cross-connects or partner connectivity) let you choose speed-to-delivery vs. direct control.

Technical reasons

Consistent latency and throughput compared to internet-based VPNs
BGP-based routing aligns with enterprise routing, enabling controlled route advertisement and failover
Private IP connectivity to VCNs via private virtual circuits
Segmentation support through DRG routing design (route tables/distributions) and separate virtual circuits

Operational reasons

Easier troubleshooting than “internet path” issues because the circuit has clearer boundaries (CE router ↔ provider ↔ Oracle)
Supports standardized network operations: change control, route filtering, redundancy testing, maintenance planning
Works alongside VPN for backup/overflow designs (common pattern)

Security / compliance reasons

Reduced exposure to the public internet for private workloads
Better alignment with regulated environments where private connectivity is preferred
(Note: “private” does not automatically mean “encrypted.” If you require encryption-in-transit, plan an overlay such as IPsec. Verify your compliance requirements and OCI options.)

Scalability / performance reasons

Higher bandwidth options than many VPN designs
Supports sustained data transfer for backup, replication, analytics ingestion, and migration

When teams should choose FastConnect

Choose FastConnect when you need:

Reliable hybrid connectivity with predictable performance
Ongoing, high-volume traffic between on-prem and OCI
Enterprise routing integration using BGP
A foundation for hybrid DR, shared services, or data replication

When teams should not choose FastConnect

FastConnect may be the wrong fit if:

You only need occasional administrative access (a VPN or bastion may be enough)
You need immediate connectivity and can’t wait for circuit provisioning lead time
Your bandwidth needs are small and intermittent, and cost/complexity of dedicated connectivity isn’t justified
You require end-to-end encryption by default and aren’t prepared to run encryption overlays or meet your security requirements with additional controls

4. Where is FastConnect used?

Industries

Financial services: low-latency trading support systems, secure hybrid connectivity, regulatory controls
Healthcare & life sciences: data transfer for imaging/analytics, compliance-driven private connectivity
Manufacturing & IoT: stable links from factories to cloud analytics platforms
Retail & e-commerce: hybrid inventory systems, analytics ingestion from data centers
Media & entertainment: high-volume content pipelines, rendering workflows, storage transfers
Public sector: secure connectivity patterns, network segmentation, data residency planning

Team types

Network engineering teams (BGP, WAN, MPLS, colocation)
Cloud platform/landing zone teams (hub-spoke design, shared services)
SRE/operations teams (monitoring connectivity health, incident response)
Security teams (segmentation, inspection, compliance)

Workloads

ERP/CRM hybrid extensions
Database replication (verify your database’s replication network requirements)
Backup/restore and archiving
Kubernetes/hybrid microservices (private service connectivity)
Big data ingestion (batch or streaming)

Architectures

On-prem ↔ OCI VCN with private subnets
Hub-and-spoke VCN with centralized DRG attachments
Dual-region DR with separate connectivity paths
Partner interconnect from colocation or other cloud

Production vs dev/test usage

Production: Common, because production traffic benefits most from predictability and redundancy.
Dev/test: Used when dev/test must mirror production networking, or when developers need access to on-prem dependencies privately. Otherwise, VPN is often the cost-effective choice.

5. Top Use Cases and Scenarios

Below are realistic scenarios where FastConnect is commonly selected. Each includes the problem, why FastConnect fits, and an example.

1) Hybrid application with private backend dependencies

Problem: An OCI-hosted web tier must call on-prem services (legacy APIs, mainframe adapters) without exposing them to the internet.
Why FastConnect fits: Provides private routing between OCI subnets and on-prem networks using BGP.
Example scenario: Customer portal runs in OCI; backend SOAP services remain on-prem. FastConnect enables private calls while keeping the on-prem network non-internet-routable.

2) Data center to OCI database replication

Problem: Ongoing replication traffic requires stable throughput and predictable latency.
Why FastConnect fits: Dedicated bandwidth and private routing reduces jitter and congestion risk common on internet paths.
Example scenario: Primary database on-prem; standby database in OCI for DR. Replication uses private IPs over FastConnect.

3) Large-scale migration and bulk data transfer

Problem: Migration requires moving many terabytes/petabytes of data without unpredictable transfer windows.
Why FastConnect fits: Supports sustained high throughput and operational control.
Example scenario: Move NAS data to OCI storage services; keep migration pipeline stable for weeks.

4) Centralized security inspection for OCI workloads

Problem: Security policy requires all north-south and on-prem traffic to be inspected by on-prem or shared security appliances.
Why FastConnect fits: Routes OCI traffic to centralized inspection points via the DRG.
Example scenario: OCI app subnet routes to on-prem next-gen firewall for DLP and IDS/IPS enforcement.

5) Multi-VCN enterprise landing zone (hub-and-spoke)

Problem: Multiple teams need isolated VCNs but shared access to on-prem services.
Why FastConnect fits: Attach multiple VCNs to a DRG and control routing centrally; connect DRG to FastConnect.
Example scenario: Shared services VCN, app VCNs per BU; on-prem connectivity is a shared service through DRG routing policies.

6) Private access to Oracle public services (public virtual circuit)

Problem: You want to reach Oracle public endpoints without traversing the public internet from your data center.
Why FastConnect fits: Public virtual circuits can provide private network access to Oracle public services (requirements apply).
Example scenario: On-prem build system uploads artifacts to OCI Object Storage public endpoint without using internet egress. (Verify whether your environment meets public VC requirements such as public prefixes/ASN.)

7) Hybrid Kubernetes connectivity

Problem: Hybrid microservices require stable east-west communication between on-prem clusters and OCI clusters.
Why FastConnect fits: Predictable connectivity improves service reliability and reduces timeouts.
Example scenario: On-prem services remain due to data sovereignty; OCI hosts new services. FastConnect supports private service-to-service communication.

8) SaaS provider extending private services into OCI

Problem: A SaaS provider needs private, dedicated connectivity for customer environments or internal systems.
Why FastConnect fits: Enables controlled, dedicated connectivity with standard routing.
Example scenario: SaaS control plane in OCI; customer-specific workloads on-prem in colocation connected via partner FastConnect.

9) Backup, archive, and restore pipelines

Problem: Backup windows are missed over VPN due to internet variability.
Why FastConnect fits: Better sustained throughput for backup data movement.
Example scenario: Nightly backups flow to OCI storage; restores are faster and more predictable during incidents.

10) Low-latency analytics ingestion from on-prem to OCI

Problem: Analytics platform in OCI needs continuous data feed from on-prem systems with low jitter.
Why FastConnect fits: Private, consistent connection supports ingestion SLAs.
Example scenario: Manufacturing telemetry collected on-prem; streamed to OCI analytics systems.

11) Partner-based connectivity for branch/colocation environments

Problem: You don’t have routers in an Oracle FastConnect location and don’t want to manage cross-connects.
Why FastConnect fits: Partner connectivity can provide an easier on-ramp.
Example scenario: You already use a connectivity fabric provider; you add a virtual connection to OCI via FastConnect Partner.

12) Regulatory-driven network segmentation

Problem: Compliance requires traffic isolation and strict routing controls across environments.
Why FastConnect fits: DRG route tables and separate virtual circuits support segmentation designs.
Example scenario: PCI workloads in one VCN only advertise specific routes to on-prem; non-PCI networks are isolated.

6. Core Features

This section focuses on widely used, current FastConnect features and the related OCI networking constructs that make them work.

6.1 Private Virtual Circuits (to VCNs via DRG)

What it does: Creates private connectivity from your network to your OCI VCNs through a DRG.
Why it matters: Most hybrid workloads need private IP reachability to OCI subnets.
Practical benefit: Run hybrid apps without exposing private services to the internet.
Limitations/caveats: Requires careful route planning (no overlapping CIDRs). You must coordinate BGP settings and redundancy.

6.2 Public Virtual Circuits (to Oracle public services)

What it does: Provides a path to Oracle public services over FastConnect rather than over the internet.
Why it matters: Some organizations want to avoid public internet paths even for public endpoints.
Practical benefit: Potentially improved reliability and controlled egress.
Limitations/caveats: Requirements differ from private virtual circuits (for example, public routing requirements). Verify exact prerequisites (public ASN, public IP prefixes, and service scope) in official docs.

6.3 FastConnect Partner connectivity option

What it does: Lets you procure connectivity through an approved partner instead of ordering and managing physical cross-connects directly.
Why it matters: Often shorter lead time and simpler operational model for teams without colocation presence.
Practical benefit: Faster onboarding; provider manages parts of the physical connectivity.
Limitations/caveats: Partner charges and operational processes vary by provider; Oracle-side configuration still requires correct BGP and DRG routing.

6.4 Dedicated physical connectivity (cross-connects)

What it does: Uses physical cross-connects at supported FastConnect locations to directly connect your equipment to Oracle.
Why it matters: Maximum control and deterministic physical path within the facility.
Practical benefit: Enterprise-grade design with explicit redundancy and facility-level controls.
Limitations/caveats: Requires presence in a FastConnect location (or a provider to deliver you there), coordination with colocation, and cabling/cross-connect lead times.

6.5 BGP routing for dynamic exchange of routes

What it does: Establishes BGP sessions between your CE router and Oracle edge to exchange reachable prefixes.
Why it matters: Dynamic routing supports scalable hybrid networks and failover designs.
Practical benefit: You can advertise on-prem routes to OCI and learn OCI routes for VCNs.
Limitations/caveats: Misconfigured BGP (ASN mismatch, IP mismatch, filters) is a top cause of outages. Use route filtering and change control.

6.6 Redundancy patterns (multiple circuits)

What it does: Supports designing for high availability by using multiple connections/virtual circuits (often with diverse paths).
Why it matters: Single circuit designs are not resilient to provider maintenance or physical failures.
Practical benefit: Higher availability hybrid connectivity.
Limitations/caveats: Redundancy is an architecture choice; you must implement it (dual CE routers, dual locations if required, etc.).

6.7 DRG integration (routing hub)

What it does: Terminates FastConnect private connectivity on a DRG, which then attaches to one or more VCNs.
Why it matters: DRG is the routing control point for hybrid connectivity and segmentation.
Practical benefit: Centralized route policy management for multiple networks.
Limitations/caveats: DRG routing is powerful but can be complex; test route tables and route distributions carefully.

6.8 Route control with VCN route tables + DRG route tables

What it does: Controls which prefixes are routed where (to FastConnect, to VCN attachments, to other attachments).
Why it matters: Prevents accidental routing (for example, sending all traffic to on-prem) and enforces segmentation.
Practical benefit: Clear blast-radius boundaries; controlled connectivity.
Limitations/caveats: A missing route rule is a common “everything looks up but nothing works” issue.

6.9 Monitoring and metrics (OCI Monitoring)

What it does: Exposes health/telemetry signals for circuits (availability, utilization, BGP state—exact metric names vary).
Why it matters: You need proactive alerting before users report outages.
Practical benefit: Alerts on BGP down, traffic anomalies, or utilization thresholds.
Limitations/caveats: Monitoring is only useful if you set alarms and operational runbooks.

6.10 Auditing and governance (OCI Audit, IAM)

What it does: Tracks API/console changes to networking resources and enforces permissions for who can modify circuits and routing.
Why it matters: Connectivity changes are high-risk; auditability and least privilege reduce incidents.
Practical benefit: Traceability, compliance support, and safer operations.
Limitations/caveats: You must enable and use governance processes; audit logs don’t prevent bad changes by themselves.

7. Architecture and How It Works

High-level architecture

FastConnect provides a private network path from your environment to OCI. At a high level:

Your on-prem CE router connects into a provider/colocation environment.
The connectivity reaches an Oracle FastConnect edge in a FastConnect location.
A virtual circuit is established and associated to a DRG (for private connectivity).
The DRG routes traffic to one or more VCNs through VCN attachments.
Subnet route tables send on-prem-bound traffic to the DRG.

Data plane vs control plane

Data plane: Your application packets flowing between on-prem subnets and OCI subnets.
Control plane: API operations (create VC, attach DRG, route table changes), plus BGP route advertisements (routing control).

Request / data / control flow (conceptual)

Control: You create networking resources in OCI (VCN, DRG, virtual circuit).
Routing: BGP sessions exchange routes between CE router and Oracle edge.
Forwarding: OCI routes packets based on VCN and DRG route policies.

Integrations with related services (common)

VCN (Virtual Cloud Network): Your private network in OCI
DRG (Dynamic Routing Gateway): The hub connecting FastConnect to VCNs (and often VPN)
Site-to-Site VPN: Frequently used as backup while FastConnect is provisioned or as a failover path
Network Security Groups (NSGs) / Security Lists: Control instance/subnet traffic at L3/L4
OCI Monitoring / Alarms: Circuit health and utilization alerting
OCI Audit: Logs changes to network resources
Compartments + Tagging: Organize and govern network objects

Dependency services

FastConnect depends on:

OCI Networking (VCN, DRG, route tables)
Physical connectivity (cross-connects) or an approved FastConnect Partner
Your CE router and WAN/provider arrangements

Security / authentication model

Access to create/modify FastConnect resources is governed by OCI IAM policies.
Network security of the traffic path is primarily governed by routing + security controls (NSGs/security lists, on-prem firewalls).
Encryption: FastConnect provides private connectivity but is not inherently the same as application-layer encryption. If you require encryption-in-transit, plan an overlay (for example, IPsec tunnels over FastConnect) and verify best practices for your compliance posture.

Networking model notes

Private virtual circuit: typically exchanges private prefixes for VCN CIDRs and on-prem CIDRs.
Public virtual circuit: typically involves public routing constructs (verify prerequisites).
Route design is everything: Most FastConnect outages are not “cable problems”—they’re route advertisements, route tables, or filtering mistakes.

Monitoring / logging / governance considerations

Use OCI Monitoring to create alarms for:
Circuit/BGP down
Sustained high utilization (capacity planning)
Sudden traffic drops/spikes (possible outage or route leak)
Use OCI Audit to track changes to:
DRG route tables/distributions
VCN route tables
Virtual circuits and attachments
Use compartments and tags to separate:
Production vs non-production circuits
Different business units
Different environments (dev/test/prod)

8. Prerequisites

Oracle Cloud tenancy and account requirements

An active Oracle Cloud tenancy with permissions to create networking resources.
A selected OCI region where you will terminate the virtual circuit and DRG.

Permissions / IAM roles

You need IAM permissions to manage networking objects such as VCNs, DRGs, and virtual circuits.

A common approach is to grant a network admin group permissions in a compartment. Example (conceptual) IAM policy statements:

Allow a group to manage networking in a compartment:
Allow group NetworkAdmins to manage virtual-network-family in compartment <compartment-name>

FastConnect objects are part of OCI networking APIs; exact policy granularity can vary. Verify required IAM permissions in the official FastConnect and IAM documentation for your organization’s least-privilege model.

Billing requirements

FastConnect is typically not Free Tier. Expect:
Oracle connectivity charges (depending on model)
Partner/carrier/colocation fees
Data egress charges (where applicable)

Tools (recommended)

OCI Console (web UI) for guided setup
OCI CLI for scripting/automation (optional)
Router/firewall configuration access on the on-prem side (CE device)
A ticketing/change management process (recommended for production)

OCI CLI: https://docs.oracle.com/en-us/iaas/Content/API/Concepts/cliconcepts.htm

Region availability and FastConnect locations

FastConnect availability depends on:
The OCI region
The presence of a FastConnect location or partner coverage

Always confirm the latest location/provider availability in official docs before design finalization.

Quotas / limits

Common quotas include limits on numbers of:

DRGs and attachments
Virtual circuits
Route rules

Quotas can be tenant-specific. Check Service Limits in the OCI Console and official documentation.

Prerequisite services

VCN and subnets
DRG
Proper routing and security rules
A CE router and provider/partner arrangement for the physical path

9. Pricing / Cost

FastConnect cost is usually a combination of Oracle-side charges plus partner/carrier/colocation charges plus data transfer charges. Exact prices vary by region, commercial agreement, and chosen model.

Pricing dimensions (typical)

Port / connection capacity charges – Dedicated connectivity models often have an Oracle-side port/hour charge based on bandwidth (for example, 1 Gbps, 10 Gbps, or higher where available). – Partner models may bundle charges differently (partner bills you; Oracle billing may differ). Verify in official pricing.
Data transfer (egress) – Even with private connectivity, data egress from OCI can be charged depending on destination and service. – Ingress is often free in many cloud models, but verify Oracle’s current network pricing rules.
Partner/carrier fees – Cross-connect fees in a colocation facility – Carrier/WAN fees for last-mile connectivity – Partner fabric port and virtual connection fees
Indirect costs – CE routers (capex), firewall capacity – Operations time (network management, incident response) – Redundancy (dual links, dual routers)

Free tier

FastConnect is generally positioned as an enterprise connectivity service and is not typically part of “always free” offerings. Verify current Oracle Cloud Free Tier details: https://www.oracle.com/cloud/free/

Cost drivers

Chosen bandwidth (higher capacity usually costs more)
Redundancy (two circuits vs one)
Location choice (colocation pricing varies; partner pricing varies)
Data egress volume from OCI to on-prem
Cross-region traffic patterns (if you hairpin through a region, you may incur additional egress)

Hidden or indirect costs to watch

Egress charges can dominate costs if you pull lots of data from OCI to on-prem.
Redundant circuits are recommended for production but double some fixed charges.
Firewall throughput licensing: private connectivity can increase traffic volumes beyond what your security stack is sized for.

How to optimize cost

Right-size bandwidth: start with realistic baselines and scale after measuring utilization.
Use monitoring alarms to detect sustained utilization (upgrade only when needed).
Avoid unnecessary backhauls:
Keep data processing close to where data resides.
If workloads are in OCI, avoid pulling large datasets back on-prem unless necessary.
Implement caching and tiering where appropriate.
Use redundancy wisely:
For critical workloads, redundancy is usually mandatory.
For dev/test, a single circuit or VPN may be acceptable.

Example low-cost starter estimate (model-based, no fabricated numbers)

A “starter” FastConnect setup commonly includes:

1× FastConnect virtual circuit (private) at the lowest suitable bandwidth tier
1× DRG and a simple VCN/subnet design
Minimal OCI compute for testing
Partner/provider charges for a single connection

Because exact prices are region- and provider-dependent, build this estimate using: – OCI Pricing pages: https://www.oracle.com/cloud/pricing/ – OCI Cost Estimator (official): https://www.oracle.com/cloud/costestimator.html (verify current URL if it changes)

Example production cost considerations

For production, expect:

Dual circuits (diverse paths), potentially in diverse locations
Higher bandwidth tiers
Ongoing partner/carrier fees
Operations overhead
Potentially significant data egress charges depending on traffic patterns

The most important financial practice is to treat connectivity as part of the application’s total cost of ownership, not as a standalone line item.

10. Step-by-Step Hands-On Tutorial

This lab focuses on what you can execute in a typical OCI tenancy without needing immediate physical provisioning. You will build the OCI-side network, create a DRG attachment, and create a FastConnect private virtual circuit request. The circuit will not pass traffic until your provider/partner and CE router configuration are completed—but the steps are real and commonly used in production onboarding.

Objective

Create an OCI network that is “FastConnect-ready”:

VCN with a private subnet
DRG with VCN attachment
Correct VCN route table rules to reach on-prem
A test compute instance in the private subnet
A FastConnect private virtual circuit request associated with the DRG
A checklist of configuration details to give to your network/provider team

Lab Overview

You will:

Create a compartment (optional) and core network objects (VCN, subnet).
Create a DRG and attach it to the VCN.
Configure routes so OCI knows to send on-prem prefixes to the DRG.
Launch a small compute instance in a private subnet for later testing.
Create a FastConnect private virtual circuit (Partner or Dedicated model—this tutorial uses Partner as it is commonly accessible).
Collect BGP and circuit details for the CE router configuration.
Validate the configuration state in OCI and prepare for turn-up.
Clean up resources.

Estimated time: 45–90 minutes (excluding provider provisioning lead time)
Cost: Low for OCI resources used in the lab; FastConnect itself and provider connectivity may incur charges depending on what you order.

Step 1: Choose a compartment and region

In the OCI Console, select the region where you want FastConnect connectivity.
Choose or create a compartment (recommended) to contain: – VCN – DRG – Virtual circuit – Compute instances

Expected outcome: You have a dedicated place to manage and audit changes.

Step 2: Create a VCN and a private subnet

Go to Networking → Virtual Cloud Networks.
Click Create VCN.
Choose VCN with Internet Connectivity only if you also want a public subnet for admin access. For this lab, you can use VCN with custom CIDR and keep it minimal.
Set: – VCN name: vcn-fastconnect-lab – CIDR block: 10.10.0.0/16 (example; choose something that does not overlap on-prem)
Create a private subnet: – Subnet name: subnet-private-app – CIDR: 10.10.1.0/24 – Mark as private (no public IP on instances by default)

Expected outcome: VCN and private subnet exist with a non-overlapping CIDR.

Verification: – Confirm the VCN CIDR and subnet CIDR in the VCN details page. – Confirm the subnet is private.

Common error: – Overlapping CIDR with on-prem. Fix by choosing a unique range before connecting.

Step 3: Create a DRG (Dynamic Routing Gateway)

Go to Networking → Dynamic Routing Gateways.
Click Create DRG.
Name: drg-fastconnect-lab

Expected outcome: DRG is created and in an Available state.

Verification: – DRG lifecycle state shows Available.

Step 4: Attach the DRG to the VCN

Open your DRG: drg-fastconnect-lab
Find DRG Attachments
Click Create DRG Attachment
Attachment type: VCN
Select VCN: vcn-fastconnect-lab
Provide an attachment name (optional): drg-attach-vcn-fastconnect-lab

Expected outcome: DRG is attached to the VCN.

Verification: – Attachment lifecycle state becomes Attached (or Available depending on console wording). – In the VCN, you can see the DRG attachment reference.

Step 5: Configure VCN routing for on-prem prefixes

In OCI, subnet route tables determine where traffic goes.

Go to Networking → Virtual Cloud Networks → vcn-fastconnect-lab
Go to Route Tables
Choose the route table associated with subnet-private-app (or explicitly associate it if needed).
Add a route rule: – Target type: Dynamic Routing Gateway (DRG) – Destination CIDR: your on-prem CIDR, for example 10.0.0.0/16 – Target: drg-fastconnect-lab

Expected outcome: Instances in the private subnet will send traffic to 10.0.0.0/16 via the DRG (once connectivity is up).

Verification: – Route table contains a rule pointing on-prem CIDR(s) to the DRG.

Common error: – Missing route rule causes “no route” even if BGP is up. Fix by adding the route to DRG.

Step 6: Configure DRG route tables / route distributions (important for real deployments)

OCI’s DRG supports route tables to control how routes are imported/exported between attachments (VCN attachment, virtual circuit attachment, VPN attachment, etc.). The exact UI and terminology can vary over time.

At minimum, ensure:

Routes learned from the FastConnect virtual circuit attachment can be used to reach on-prem
Routes to your VCN CIDRs are advertised/available to the FastConnect attachment

Because DRG routing capabilities are powerful and sometimes non-obvious, follow the latest official guidance for: – DRG route tables – Route distributions – Import/export behavior between attachments

Expected outcome: DRG is prepared to exchange routes between your VCN and the future FastConnect attachment.

Verification: – In DRG route tables, confirm VCN CIDR route presence (static/attached). – After FastConnect is live, confirm on-prem routes appear as learned routes.

Note: If you are unsure which DRG routing model applies to your tenancy/region/version, verify in official docs and test in a non-production compartment first.

Step 7: Create a test compute instance (private)

This gives you a destination to test reachability once FastConnect is live.

Go to Compute → Instances → Create instance
Name: vm-fastconnect-test
Image: Oracle Linux (or your standard)
Shape: choose a small, low-cost shape suitable for your tenancy
Networking: – VCN: vcn-fastconnect-lab – Subnet: subnet-private-app – Public IP: Do not assign (private instance)
Ensure you have SSH keys if you plan to access it via bastion/VPN.

Expected outcome: A private VM exists in the subnet.

Verification: – Instance shows Running – Note its private IP address (for later ping/SSH from on-prem once connected)

Step 8: Create a FastConnect private virtual circuit (Partner model)

You can create the virtual circuit request in OCI even if the physical/provisioning work is not completed yet.

Go to Networking → FastConnect
Click Create Connection or Create Virtual Circuit (wording can vary)
Choose FastConnect Partner (commonly used for fabric providers)
Virtual circuit type: Private
Select the DRG: drg-fastconnect-lab
Configure BGP details: – Customer ASN (private ASN is typically acceptable for private VC; confirm with your network team) – BGP IP addresses (/30 or /31 addressing as required by OCI; the console will guide you) – Optional: BGP authentication key if your policy requires it (verify support and requirements)
Bandwidth: choose the smallest suitable bandwidth tier for a lab (availability varies by partner/location)
Provide a name: vc-fastconnect-private-lab

Expected outcome: Virtual circuit is created in a provisioning state (often something like “Pending Provider” until the partner completes their side).

Verification: – Virtual circuit exists and is associated with the DRG. – Lifecycle state indicates it is waiting for provider action or cross-connect completion.

Common errors: – Wrong DRG selected (leading to routing confusion). Fix by ensuring the VC attaches to the intended DRG. – IP addressing mismatch. Fix by re-checking the BGP peer IPs and subnet requirements.

Step 9: Collect information for your CE router / provider

From the virtual circuit details page, capture:

Virtual circuit OCID and name
Circuit type: Private
BGP peer IPs (Oracle and customer sides)
VLAN information (if applicable/required by the model)
Oracle BGP ASN (if provided)
Your customer ASN (what you entered)
Advertised prefixes:
On-prem prefixes you will advertise to OCI (for example 10.0.0.0/16)
OCI VCN prefixes you expect to learn (for example 10.10.0.0/16)

Provide this to: – Your network team (CE router configuration) – Your provider/partner (to complete provisioning)

Expected outcome: Your provider/network team has all parameters needed to configure their side.

Step 10 (Optional): Prepare a CE router BGP configuration template

Router syntax varies by vendor. Below is a Cisco IOS-style example to show the intent. Do not paste this into production without adapting it to your router platform, interface naming, and your organization’s standards. Verify in official docs and with your network team.

! Example only — adapt to your router and FastConnect design
router bgp <YOUR_ASN>
  neighbor <ORACLE_BGP_PEER_IP> remote-as <ORACLE_ASN>
  neighbor <ORACLE_BGP_PEER_IP> description OCI FastConnect Private VC
  !
  address-family ipv4
    neighbor <ORACLE_BGP_PEER_IP> activate
    network 10.0.0.0 mask 255.255.0.0
  exit-address-family

Operational best practice: apply route-maps / prefix-lists so you only advertise and accept intended routes.

Validation

Because the circuit will not become fully operational until the provider and physical components are complete, validation happens in two phases.

Phase A (immediate validation in OCI)

Virtual circuit exists and is attached to the DRG
DRG is attached to the VCN
Subnet route table includes route(s) to on-prem CIDR(s) via DRG
No CIDR overlap between VCN and on-prem ranges

Phase B (post-provisioning validation)

Once the provider confirms the circuit is up and BGP is configured:

Check the virtual circuit status in OCI shows Up/Provisioned (exact wording varies).
Confirm BGP session is established (OCI console often shows BGP status).
Confirm DRG route tables show learned routes for on-prem prefixes.
From on-prem, test: – ping <private-ip-of-vm-fastconnect-test> – traceroute <private-ip> (as allowed)
From the OCI instance (if you can access it through bastion/VPN): – ping <on-prem-test-ip> – Application-level tests (TCP connection to on-prem services)

Expected outcome: Private connectivity works bidirectionally for allowed routes and security rules.

Troubleshooting

Common issues and fixes:

BGP is down – Check ASN match, peer IPs, and interface/VLAN configuration – Ensure provider completed provisioning – Confirm BGP authentication settings if used
BGP is up but traffic doesn’t flow – Check VCN subnet route table sends on-prem CIDRs to DRG – Check DRG route table/distribution allows route propagation between attachments – Check security lists/NSGs on the OCI instance subnet – Check on-prem firewall rules and return path routing
Only some prefixes work – Check route filters on CE router – Ensure OCI route tables and DRG route tables include the required routes – Confirm there is no overlapping CIDR causing ambiguous routing
Asymmetric routing – Ensure both sides learn and prefer the same paths – Use consistent BGP attributes and route policies – Validate that multiple circuits do not create unexpected routing preference
MTU-related issues (large packets drop) – Confirm end-to-end MTU settings across CE router, provider, and OCI expectations – If you see fragmentation problems, test with smaller packet sizes – Verify FastConnect MTU behavior in official docs

Cleanup

If you are not proceeding to a real circuit turn-up, clean up to avoid ongoing charges:

Terminate the compute instance vm-fastconnect-test
Delete the virtual circuit vc-fastconnect-private-lab (if it won’t be used)
Detach and delete the DRG (after removing attachments)
Delete the VCN vcn-fastconnect-lab

Note: If you engaged a partner/provider order, cancel it through the provider’s process as well—deleting OCI objects alone may not stop partner billing.

11. Best Practices

Architecture best practices

Design for redundancy
Two circuits (ideally diverse) for production
Dual CE routers and diverse physical paths where possible
Use hub-and-spoke with DRG for enterprises
Attach multiple VCNs to a DRG
Centralize route control and segmentation
Avoid overlapping CIDRs
Establish an IPAM strategy early
Reserve CIDR space for future VCNs and on-prem expansions
Plan for multi-region
If workloads span regions, design routing intentionally (do not “accidentally” hairpin traffic)
Use official OCI reference architectures for multi-region networking

IAM / security best practices

Least privilege for networking changes
Separate “view” vs “manage” permissions
Restrict who can change DRG route tables and virtual circuits
Use compartments
Separate production and non-production
Separate network hub from application compartments if your governance model requires it
Tag critical connectivity resources
Owner, environment, cost center, change window group

Cost best practices

Start with realistic bandwidth and scale based on observed utilization.
Avoid unnecessary data egress by keeping data processing in OCI when possible.
Monitor utilization and set alarms to detect saturation early.

Performance best practices

Prefer private connectivity for latency-sensitive or throughput-heavy workloads.
Validate MTU settings end-to-end.
Use route filtering to keep routing tables clean and stable.

Reliability best practices

Implement circuit redundancy and regularly test failover.
Maintain a VPN backup path where appropriate (especially during initial provisioning).
Document and rehearse incident runbooks:
“BGP down”
“Provider outage”
“Route leak / wrong route advertised”

Operations best practices

Use monitoring alarms (BGP down, utilization thresholds).
Enable and regularly review OCI Audit events for network changes.
Use infrastructure-as-code for repeatability (Terraform is common in OCI; verify provider modules and resources in official docs).

Governance / tagging / naming best practices

Use consistent names:
drg-<env>-<region>-<purpose>
vc-<env>-<type>-<location>-<id>
Tag with:
Environment=Prod|Dev
Owner=<team>
CostCenter=<code>
Criticality=High|Medium|Low

12. Security Considerations

Identity and access model

FastConnect resources are controlled via OCI IAM.
Apply least privilege:
A small set of admins can manage DRGs and virtual circuits.
Broader teams can have read-only access for troubleshooting.

Encryption

FastConnect provides private connectivity, but encryption is not guaranteed by “private circuit” alone.
If encryption-in-transit is required:
Use application-layer encryption (TLS)
Or consider an IPsec overlay (for example, tunnels over FastConnect) if it fits your design and performance goals
Verify Oracle’s recommended patterns and any service constraints in official docs.

Network exposure and segmentation

Use separate VCNs/subnets and DRG route policies to limit lateral movement.
Enforce security at multiple layers:
On-prem firewall
OCI NSGs/security lists
Instance-level host firewall where appropriate

Secrets handling

If you use BGP authentication keys or device credentials:
Store secrets in a secure vault solution
Restrict access and rotate per policy
Avoid embedding secrets in code repositories

Audit / logging

Use OCI Audit to track changes to:
Virtual circuits
DRG route tables and attachments
VCN route tables
Keep logs for compliance retention requirements.

Compliance considerations

Private connectivity can help satisfy controls related to network exposure, but compliance usually requires:
Encryption requirements (if mandated)
Change management evidence
Logging/auditing and access controls
Documented network diagrams and routing policies

Common security mistakes

Treating FastConnect as “secure by default” without encryption assessment
Over-advertising routes (route leaks)
Allowing too many admins to modify routing/virtual circuits
Using broad security list rules (0.0.0.0/0) inside private subnets

Secure deployment recommendations

Implement strict route filters on CE routers.
Use DRG route segmentation to restrict which VCNs can reach on-prem networks.
Use NSGs for workload-level segmentation.
Document and review routing changes in a formal change process.

13. Limitations and Gotchas

Provisioning lead time: Dedicated circuits require coordination with providers/colocation; it is not instant.
Location constraints: You can only connect where FastConnect locations/partners exist.
Complexity: DRG routing policies and multi-attachment routing can be complex; test changes.
No automatic encryption guarantee: Private connectivity is not the same as encrypted connectivity.
CIDR overlap breaks designs: Overlaps between VCN CIDRs and on-prem CIDRs cause routing ambiguity.
Public virtual circuit prerequisites: Often stricter (public routing prerequisites). Verify exact requirements.
Operational responsibility: Oracle provides the cloud-side termination, but you still own:
CE router configuration
Route filtering
On-prem firewalling
Coordination with the partner/carrier
Quotas/service limits: Limits exist and can block scaling if not planned (number of VCs, route rules, DRG attachments). Check service limits early.
Data egress surprises: Hybrid designs can inadvertently pull data out of OCI and create unexpected egress cost.

14. Comparison with Alternatives

FastConnect is one option in a broader connectivity toolbox.

Key alternatives

OCI Site-to-Site VPN: Internet-based IPsec VPN connectivity to OCI (faster to deploy; less predictable performance).
Provider MPLS / WAN only (no direct cloud on-ramp): Can be used to reach a partner that provides FastConnect connectivity.
Other cloud equivalents: AWS Direct Connect, Azure ExpressRoute, Google Cloud Interconnect.
Self-managed VPN overlays: IPsec/GRE tunnels over the internet or over private links.

Expected outcomes:
Faster and more predictable data sync jobs
Easier scaling into OCI services over time
A clear path to redundancy as the company grows

16. FAQ

Is FastConnect the same as a VPN?
No. FastConnect is private/dedicated connectivity; VPN is encrypted tunneling over the internet (typically). Many architectures use both: FastConnect as primary, VPN as backup.
Does FastConnect automatically encrypt my traffic?
Not necessarily. It provides private connectivity. If your policy requires encryption-in-transit, use TLS at the application layer or consider an IPsec overlay design. Verify compliance requirements.
What do I need on-prem to use FastConnect?
Typically a CE router (or firewall/router) capable of BGP, connectivity to a FastConnect location or partner, and the ability to implement route filters and redundancy.
Can I use FastConnect for multiple VCNs?
Yes. Commonly you terminate FastConnect on a DRG and attach multiple VCNs to that DRG, controlling routing using route policies.
What’s the difference between a private and a public virtual circuit?
Private VCs are for VCN private connectivity. Public VCs are for reaching Oracle public services over FastConnect. Public VCs often require public routing prerequisites—verify exact requirements.
How long does FastConnect provisioning take?
It depends on whether you use a partner model or dedicated cross-connects, and on provider/colocation lead times. Plan for days to weeks in many real-world cases.
Can I build a lab without ordering a circuit?
You can build the OCI-side network (VCN, DRG, route tables) and create a virtual circuit request, but you can’t pass traffic until the provider and CE router setup is complete.
Do I still need an Internet Gateway in my VCN?
Not for private on-prem connectivity. You may still need internet egress for patching or public services depending on your design (or use NAT Gateway/service gateways as appropriate).
How do I prevent route leaks from on-prem into OCI?
Use strict prefix-lists/route-maps on your CE router, and carefully control route import/export on the DRG route tables.
Can FastConnect be used as a backup to VPN or vice versa?
Yes. Often VPN is a backup to FastConnect because it is independent of the same physical path.
What’s the role of the DRG in FastConnect?
DRG is the OCI routing hub that terminates the private connectivity and connects to one or more VCNs.
Can I connect multiple on-prem sites to OCI using FastConnect?
Yes, but you must design routing carefully. You may connect multiple sites via your WAN to a FastConnect location, or use multiple circuits/partners.
What are the most common causes of FastConnect outages?
Misconfigured BGP (ASN/IP/auth), missing route table rules, route leaks, or provider-side maintenance/physical issues.
Does FastConnect reduce OCI data egress charges?
Pricing and egress rules vary and can change. Do not assume it’s cheaper by default—check official pricing for your region and usage.
Can I use FastConnect to access OCI services privately from my data center?
You can access VCN resources privately using private virtual circuits. For Oracle public services, public virtual circuits may apply—verify scope and requirements.

22. Glossary

ASN (Autonomous System Number): Identifier used in BGP to represent a routing domain.
BGP (Border Gateway Protocol): Dynamic routing protocol used to exchange routes between networks.
CE Router (Customer Edge): Your router/firewall that peers with Oracle via BGP.
CIDR: IP address range notation (for example, 10.10.0.0/16).
Compartment (OCI): Logical isolation boundary for organizing and controlling resources.
Cross-connect: Physical cable connection between your equipment/provider and Oracle in a FastConnect location (dedicated model).
DRG (Dynamic Routing Gateway): OCI virtual router that connects VCNs to external networks (FastConnect/VPN).
FastConnect Location: Facility where Oracle provides FastConnect termination or partner connectivity exists.
NSG (Network Security Group): OCI construct to apply security rules to VNICs/instances.
Route table: Rules that determine how traffic is forwarded.
Virtual Circuit (FastConnect): Logical connection over FastConnect where BGP and bandwidth are configured.
VCN (Virtual Cloud Network): Your private network in OCI.
VLAN: Layer 2 segmentation often used in circuit provisioning (implementation depends on model/provider).

23. Summary

FastConnect is Oracle Cloud’s dedicated private connectivity service in the Networking, Edge, and Connectivity category. It connects your on-premises or colocation network to OCI using private circuits and BGP, typically terminating on a DRG to reach VCNs.

It matters because it delivers more predictable performance and operational control than internet-based VPNs, enabling serious hybrid cloud architectures for production workloads. Cost is driven by the chosen connectivity model (partner vs dedicated), bandwidth, redundancy, provider/colocation fees, and data egress. Security-wise, FastConnect reduces exposure to the public internet, but you must still evaluate encryption requirements and implement routing and IAM controls carefully.

Use FastConnect when hybrid connectivity is critical, sustained, and performance-sensitive. Start your next learning step by mastering DRG routing behavior and building a repeatable OCI-side connectivity baseline (VCN + DRG + route policies + monitoring), then coordinate with your provider/network team for the physical turn-up.
