AWS Amplify Tutorial: Architecture, Pricing, Use Cases, and Hands-On Guide for Frontend web and mobile

1. Introduction

AWS Amplify is an AWS service and toolset for building and shipping full-stack frontend web and mobile applications. It combines managed hosting and CI/CD for frontend apps with developer tooling to connect common backend capabilities like authentication, APIs, storage, and serverless functions—without requiring you to assemble every piece from scratch.

In simple terms: AWS Amplify helps you go from “code in a Git repo” to a deployed web app (often globally cached via a CDN), and it can also provision the cloud backend your app needs (sign-in, data, files) using AWS best practices.

Technically, AWS Amplify includes: – Amplify Hosting (a managed CI/CD + hosting service for web apps, including popular frameworks and some SSR patterns), – Amplify Studio (a visual environment for building app backends and UI components), – Amplify Libraries and UI components (client SDKs and UI building blocks for JavaScript, iOS, Android, Flutter, etc.), – Tooling that can provision backend resources (commonly via AWS CloudFormation under the hood for many workflows).

The core problem it solves: frontend teams need a reliable, secure, scalable, and repeatable way to deploy web apps and connect them to backend services—without becoming infrastructure experts or spending weeks wiring CI/CD, CDN, auth, APIs, and environments manually.

Naming note (current status): AWS Amplify is an active service. You may still see references to “Amplify Console” in older materials; today the hosting/CI/CD portion is commonly referred to as Amplify Hosting within the broader AWS Amplify product family. Always verify the latest terminology and workflows in the official docs: https://docs.amplify.aws/

2. What is AWS Amplify?

Official purpose

AWS Amplify is designed to help developers build, deploy, and host full-stack applications—especially in Frontend web and mobile scenarios—by integrating frontend development workflows with AWS backend services.

Core capabilities

Frontend hosting + CI/CD from Git providers (build, deploy, branch previews, rollbacks).
Backend building blocks like authentication, APIs, storage, and functions (using AWS services such as Amazon Cognito, AWS AppSync, Amazon S3, AWS Lambda, Amazon DynamoDB).
Client libraries and UI components to connect apps to AWS services with consistent patterns.
Environment management (e.g., dev/test/prod separation), depending on the workflow used.

Major components (practical view)

Component	What it is	Where you use it
Amplify Hosting	Managed CI/CD and hosting for web apps	AWS Console, connected to Git
Amplify Studio	Visual development environment (data models, auth, UI components, etc.)	AWS Console (Studio)
Amplify Libraries	SDK-style libraries for app integration	Your app code (JS/iOS/Android/Flutter)
Amplify UI	Prebuilt UI components (e.g., sign-in screens)	Your frontend code
Backend provisioning tooling	Mechanism to create AWS resources for your app	Commonly CLI or Studio workflows (verify latest recommended approach in docs)

Service type

AWS Amplify is best thought of as: – A managed hosting/CI/CD service (Amplify Hosting), – Plus a developer platform (Studio + libraries) that integrates with multiple AWS services.

Scope: regional/global/account considerations

Amplify Hosting typically provisions a globally distributed delivery layer (commonly via Amazon CloudFront) while your Amplify app configuration is created in a chosen AWS Region. The exact mechanics can vary; verify in official docs for your region.
Backend services used by Amplify (e.g., Cognito, AppSync, DynamoDB, S3, Lambda) are generally regional.
AWS Amplify is account-scoped (belongs to an AWS account) and you control access via IAM.

How it fits into the AWS ecosystem

AWS Amplify sits at the intersection of: – Frontend deployment (CI/CD, hosting, CDN behavior, custom domains, environment variables), – Serverless application backends (auth, APIs, storage, functions), – Developer experience (SDKs, UI components, environment workflows).

It often complements (not replaces) services like: – Amazon CloudFront + S3 (for static hosting), – AWS CodeBuild/CodePipeline (for CI/CD), – AWS AppSync / API Gateway (for APIs), – Amazon Cognito (for authentication).

3. Why use AWS Amplify?

Business reasons

Faster time-to-market: ship a working web app with CI/CD in hours, not weeks.
Lower coordination overhead: frontend teams don’t need to assemble multiple AWS services manually to get a baseline deployment pipeline.
Scales with the organization: easy dev/stage/prod patterns and branch-based workflows.

Technical reasons

Opinionated but flexible: provides a “golden path” for many common frontend + serverless patterns.
Tight integration with AWS primitives: Cognito, AppSync, DynamoDB, S3, Lambda, CloudFront are common building blocks.
Framework support: Amplify Hosting supports many modern frontend frameworks and build systems (verify your exact framework/version compatibility in the hosting docs).

Operational reasons

Managed CI/CD: build logs, deploy history, rollbacks, branch previews.
Repeatable deployments: Git-based pipelines reduce “works on my machine” issues.
Environment isolation: workflows can support multiple environments (implementation varies; verify current best practices for your chosen Amplify workflow).

Security/compliance reasons

IAM-based access control to manage who can deploy, configure domains, and manage backend resources.
TLS support for custom domains (typically via ACM-managed certificates, depending on setup).
Auditability via AWS logging services (CloudTrail for API activity; build logs in Amplify; additional service logs for backend components).

Scalability/performance reasons

CDN-backed hosting is typically global, reducing latency for users.
Backend scaling is usually handled by underlying AWS services (Cognito, AppSync, DynamoDB, Lambda), which are designed for elastic workloads.

When teams should choose AWS Amplify

Choose AWS Amplify when: – You want managed frontend hosting + CI/CD tightly integrated with AWS. – You’re building web apps (SPA, SSR-capable frameworks) and want predictable deployments and branch previews. – You want a pragmatic path to add auth, APIs, and storage without building everything from scratch. – You want a single operational surface area for frontend delivery and common backend needs.

When teams should not choose AWS Amplify

Avoid or reconsider AWS Amplify when: – You need full control of CDN configuration, WAF attachment, advanced edge logic, or custom networking beyond what Amplify exposes. (You can often build with CloudFront/S3/CodePipeline directly instead.) – You require VPC-only access patterns for hosting origins (Amplify Hosting is managed; network-level customizations are limited). – Your organization already standardized on a different platform (e.g., Vercel/Netlify/Firebase) and the switching cost outweighs benefits. – You have highly specialized CI/CD needs (custom runners, complex deployment orchestration) better served by bespoke pipelines.

5. Top Use Cases and Scenarios

Below are realistic, commonly implemented AWS Amplify scenarios.

1) Host a React/Vue/Angular single-page application (SPA)

Problem: Need a reliable, CDN-backed web hosting setup with CI/CD.
Why AWS Amplify fits: Git-based deployments, build settings, fast global delivery, easy rollbacks.
Example: Marketing site + SPA dashboard deployed from GitHub with separate dev and main branches.

2) Preview deployments for pull requests

Problem: Review UI changes before merging without manual environments.
Why it fits: Amplify Hosting supports branch-based and PR preview flows (depending on Git provider integration).
Example: Each PR gets a unique preview URL for QA and product review.

3) Add user authentication to a frontend app

Problem: Implement secure sign-up/sign-in, password resets, MFA.
Why it fits: Amplify Libraries and UI components integrate with Amazon Cognito.
Example: A B2B portal with Cognito-hosted user pools and group-based access.

4) Build a GraphQL API for a frontend app

Problem: Need a typed API with flexible queries and real-time updates.
Why it fits: Amplify workflows commonly integrate with AWS AppSync (GraphQL).
Example: A project management tool with GraphQL queries and subscriptions.

5) Build a REST API for a frontend app

Problem: Need REST endpoints backed by Lambda or other services.
Why it fits: Amplify Libraries can call REST endpoints; backend can use API Gateway + Lambda patterns.
Example: A contact form service with validation and spam checks.

6) File uploads and user-generated content

Problem: Securely upload/download images and documents.
Why it fits: Amplify Libraries integrate with S3 patterns, including auth-based access.
Example: A real estate portal where authenticated users upload listing photos.

7) Multi-environment deployments (dev/stage/prod)

Problem: Prevent dev changes from affecting production.
Why it fits: Amplify supports environment concepts depending on workflow; hosting supports branch-based isolation.
Example: main deploys to production domain; develop deploys to staging domain.

8) Admin dashboard with role-based access control

Problem: Provide internal admin tooling with strict permissions.
Why it fits: Cognito groups/claims + application-level authorization.
Example: Customer support dashboard restricted to “SupportAgent” group.

9) Offline-first app patterns (mobile or web)

Problem: Users need a functional experience with intermittent connectivity.
Why it fits: Amplify has offered client-side data sync patterns in certain workflows; verify current recommended approach for your platform and generation of Amplify tooling.
Example: Field service app that syncs updates when online.

10) Rapid prototyping of a full-stack MVP

Problem: Build an MVP quickly with minimal infrastructure assembly.
Why it fits: Hosted frontend + managed auth + serverless backend building blocks.
Example: Startup MVP with authentication, basic data storage, and file uploads.

11) Host Next.js (or similar) with SSR patterns

Problem: Need SEO-friendly SSR pages and dynamic rendering.
Why it fits: Amplify Hosting supports certain SSR deployment patterns; verify your framework version and build settings in official hosting docs.
Example: Product catalog site with SSR pages plus authenticated SPA dashboard.

12) Centralized frontend delivery for micro-frontend teams

Problem: Multiple teams deliver UI independently; need consistent deployments.
Why it fits: Amplify Hosting can host multiple apps/branches; micro-frontend composition patterns are possible but require careful design.
Example: Separate repos for “checkout”, “account”, and “catalog” components integrated at runtime.

6. Core Features

This section focuses on important, current AWS Amplify capabilities. Where details vary by framework or workflow generation, it’s called out.

1) Amplify Hosting (managed CI/CD + hosting)

What it does: Connects your Git repo (e.g., GitHub) to build and deploy your frontend automatically.
Why it matters: Reduces operational effort; makes deployments repeatable.
Practical benefit: Push to main triggers build → deploy; you get a stable URL and deploy history.
Caveats: Some advanced CDN/WAF features may not be directly configurable from Amplify; verify capabilities needed for regulated environments.

2) Branch-based deployments and previews

What it does: Deploy each branch (and optionally PRs) to its own environment.
Why it matters: Enables safe testing and review.
Practical benefit: QA and stakeholders can validate before merge.
Caveats: More branches mean more builds and potential cost; manage retention.

3) Build settings and build pipelines (amplify.yml)

What it does: Define install/build artifacts, caching, and environment variables.
Why it matters: Standardizes builds across developers and CI.
Practical benefit: Faster builds with caching; consistent Node versions (where supported).
Caveats: Complex monorepos may require custom configuration.

4) Custom domains and TLS

What it does: Map a domain to your Amplify hosted app, typically with managed TLS certificates.
Why it matters: Production-grade user experience and security.
Practical benefit: app.example.com with HTTPS.
Caveats: DNS validation, certificate issuance, and subdomain routing must be planned; domain costs are separate.

5) Redirects, rewrites, and custom headers

What it does: SPA routing support, redirects, and header injection for security and caching.
Why it matters: Avoids 404s on client routes; improves security headers (CSP, HSTS where appropriate).
Practical benefit: /dashboard routes to index.html for SPAs.
Caveats: Incorrect rewrite rules can break asset loading.

6) Environment variables and build-time secrets

What it does: Inject configuration at build time (API URLs, feature flags).
Why it matters: Avoid hardcoding environment-specific values.
Practical benefit: Different configs for staging vs prod branches.
Caveats: Treat variables as sensitive when appropriate; don’t expose secrets to the browser.

7) Amplify Libraries (client SDKs)

What it does: Provides consistent client APIs to call auth, APIs, storage, etc.
Why it matters: Reduces boilerplate and integrates with AWS best practices.
Practical benefit: Simple Auth/API/Storage patterns (exact APIs depend on library version).
Caveats: Library versions evolve; verify current import patterns in official docs: https://docs.amplify.aws/

8) Amplify UI (prebuilt components)

What it does: UI components for auth flows and common patterns.
Why it matters: Fast, consistent sign-in UX.
Practical benefit: <Authenticator> component for React can deliver sign-in/up quickly.
Caveats: Customize responsibly; ensure accessibility and brand requirements.

9) Authentication integration (commonly Amazon Cognito)

What it does: Adds user pools, federated identity patterns, and client integration.
Why it matters: Secure, scalable identity management for apps.
Practical benefit: Password policy, MFA, email verification, hosted UI options.
Caveats: Cognito configuration must match your security requirements (MFA, account recovery, compliance).

10) API integration (commonly AppSync GraphQL and/or API Gateway REST)

What it does: Connect frontend apps to APIs with auth-aware clients.
Why it matters: Enables secure data access patterns.
Practical benefit: Typed GraphQL schema and resolvers (AppSync) or REST endpoints (API Gateway).
Caveats: Authorization models must be designed (public/private, per-user data, admin roles).

11) Storage integration (commonly Amazon S3)

What it does: Store and retrieve user files.
Why it matters: Decouple file storage from your app servers.
Practical benefit: Direct browser/mobile uploads with controlled permissions.
Caveats: Public vs private objects, lifecycle rules, and data classification matter.

12) Observability for builds and deployments

What it does: Provides build/deploy logs and status in the Amplify console.
Why it matters: Faster troubleshooting.
Practical benefit: View build failures without setting up separate CI logging.
Caveats: Application runtime logging for APIs/functions is in their respective services (CloudWatch, etc.).

7. Architecture and How It Works

High-level service architecture

AWS Amplify commonly splits into: 1. Frontend delivery plane (Amplify Hosting): build + deploy + CDN delivery 2. Backend plane (optional, depending on your app): auth, APIs, storage, functions implemented using underlying AWS services

Request/data/control flow (typical)

Control plane (developers/operators):
Developer pushes code to Git provider
Amplify pulls code, runs build steps, deploys artifacts
Operators configure domains, environment variables, and rewrites
Data plane (end users):
Users access the app via HTTPS
CDN caches static assets globally
Browser calls APIs (GraphQL/REST) with auth tokens
APIs read/write data (e.g., DynamoDB) or trigger functions (Lambda)
Files uploaded to S3 under controlled access

Integrations with related AWS services

Common underlying services (depends on features you enable): – Amazon CloudFront (global content delivery, often used under Amplify Hosting) – Amazon S3 (build artifacts and/or app storage) – AWS CodeBuild (build execution, commonly used internally by hosting workflows) – Amazon Cognito (user authentication) – AWS AppSync (GraphQL API) – Amazon API Gateway (REST API) – AWS Lambda (serverless functions) – Amazon DynamoDB (NoSQL database) – AWS CloudWatch (metrics/logs for underlying services) – AWS CloudTrail (audit log of API calls) – AWS Certificate Manager (ACM) (TLS certificates for custom domains, depending on setup) – Amazon Route 53 (DNS management, if you use it)

Dependency services

Amplify doesn’t replace these services; it orchestrates and integrates with them. Your final architecture and billing include whichever AWS services you enable.

Security/authentication model (typical)

Admin/operator access: IAM permissions to Amplify and underlying services.
User authentication: often Cognito user pools (JWT tokens).
API authorization: AppSync auth modes or API Gateway authorizers.
Storage authorization: S3 bucket policies and IAM roles (sometimes mediated via Cognito identity pools depending on pattern).

Networking model

Amplify Hosting: internet-facing HTTPS endpoints (CDN).
Backend services: generally public AWS service endpoints with authentication (Cognito/AppSync/API Gateway). Private-only endpoints require more advanced patterns and may not be a direct fit for Amplify Hosting alone.

Monitoring/logging/governance

Build logs: available in Amplify console.
Backend logs: CloudWatch Logs (Lambda), AppSync logs (if enabled), API Gateway access logs (if configured), etc.
Governance: tag resources, enforce IAM boundaries, consider AWS Organizations SCPs for enterprise guardrails.

Note: The exact underlying components used by Amplify Hosting and the best-practice backend approach can vary by framework and by “generation” of Amplify tooling. Verify current reference architectures in official docs.

8. Prerequisites

Account and billing

An AWS account with billing enabled.
A plan for cost control (budgets/alerts recommended).

IAM permissions

You need an IAM principal (user/role) that can: – Create/manage Amplify apps (Amplify Hosting) – If provisioning backend resources (as in this tutorial): permissions for services like: – AWS CloudFormation – Amazon Cognito – IAM (role creation) – Amazon S3 – (Optional) AppSync, DynamoDB, Lambda – In enterprises, use least privilege and consider a dedicated deployment role.

For exact permissions, follow the official Amplify documentation and your organization’s IAM standards. Avoid using AdministratorAccess in production.

Tools (for this tutorial)

Node.js LTS (verify current supported versions for your framework and Amplify build images)
npm (or yarn/pnpm; keep consistent with your repo)
Git
Amplify CLI (for the backend portion of the lab; see docs)
Official docs entry point: https://docs.amplify.aws/

Git provider account

GitHub account (or supported Git providers). This tutorial uses GitHub.

Region availability

Amplify availability varies by region. Choose a region supported by Amplify Hosting and your backend services.
Confirm in AWS Regional Services List and Amplify docs:
https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/

Quotas/limits

Amplify and underlying services have quotas (apps/branches/build minutes/concurrency, Cognito limits, etc.).
Check:
Service Quotas in AWS Console
Amplify documentation for Hosting and backend-specific limits
If a specific number matters, verify in official docs because quotas change over time.

Prerequisite services (implicit)

For hosting: DNS (optional), ACM (custom domains).
For auth and backend: Cognito, CloudFormation, IAM.

9. Pricing / Cost

AWS Amplify cost typically comes from two places: 1. Amplify Hosting charges (build and hosting) 2. Underlying AWS services you use for backend features (Cognito, S3, AppSync, DynamoDB, Lambda, etc.)

Official pricing sources

AWS Amplify pricing page: https://aws.amazon.com/amplify/pricing/
AWS Pricing Calculator: https://calculator.aws/

Amplify Hosting pricing dimensions (typical model)

Amplify Hosting commonly charges for: – Build & deploy: build minutes (CI time), including provisioning and build execution – Hosting/storage: amount of artifacts stored – Data transfer: data served to users (outbound), and requests

Exact prices vary by region and can change—do not rely on blog numbers; verify on the official pricing page.

Free tier

AWS often provides a free tier for Amplify Hosting (for a limited amount of build minutes and hosting/requests). Free tier details can change—verify: – https://aws.amazon.com/amplify/pricing/

Cost drivers (direct)

Number of builds per day (CI frequency, PR previews, branch builds)
Build duration (large dependencies, no caching, slow tests)
Data transfer out (traffic volume, large assets)
Number and size of artifacts stored

Indirect/hidden costs (common surprises)

Custom domains: domain registration costs (Route 53 or third-party)
Data transfer: large images/videos can drive costs quickly
Backend services:
Cognito MAUs, SMS MFA (SMS can be costly)
DynamoDB read/write capacity (or on-demand request volume)
Lambda invocations and duration
S3 storage + requests
CloudWatch logs ingestion/storage
Multiple environments: dev/stage/prod stacks multiply baseline costs

Network/data transfer implications

Serving content globally typically involves CDN data transfer pricing characteristics.
API calls from browser to AWS endpoints incur request charges on those services, and data transfer can apply.
If your app is used globally, consider caching, compression, and asset optimization to reduce cost.

How to optimize cost (practical)

Use asset optimization: compress images, code-splitting, minification.
Turn on build caching (node_modules caching) where supported.
Reduce unnecessary builds: limit PR previews to active repos or configure branch patterns.
Use separate AWS accounts for dev/test vs prod to contain blast radius and cost.
Set AWS Budgets and alerts early.

Example low-cost starter estimate (no fabricated numbers)

A starter project that: – Deploys a small SPA – Has low traffic (few users) – Does a handful of builds per week …often fits within free tier or low monthly spend, depending on region and free tier availability.

Use the AWS Pricing Calculator and plug in: – Estimated build minutes/month – GB stored – GB served/month – Requests/month

Example production cost considerations

In production, costs are driven by: – High traffic (GB served and request volume) – High CI activity (multiple merges per day, PR previews) – Backend consumption (Cognito MAUs, API call volume, database reads/writes, storage)

For production forecasting: – Model multiple scenarios: baseline, expected, peak – Include CloudWatch logs and operational tooling – Include data transfer out and API request costs – Validate with load tests and real usage metrics after launch

10. Step-by-Step Hands-On Tutorial

This lab builds a small, real web application and deploys it using AWS Amplify Hosting, with Amazon Cognito authentication provisioned via Amplify tooling and integrated into the React frontend.

This is intentionally designed to be: – Beginner-friendly – Low-cost for small test usage – Practical and close to real production workflows (Git-based CI/CD)

Tooling note: AWS Amplify has evolved over time and may offer multiple workflow “generations.” This lab uses a CLI-driven workflow that is widely used. Verify the current recommended approach in official docs if you prefer newer patterns: https://docs.amplify.aws/

Objective

Deploy a React SPA with: – CI/CD hosting via AWS Amplify Hosting – User sign-in/sign-up UI using Amplify UI – Authentication backed by Amazon Cognito – A GitHub-connected deployment pipeline

Lab Overview

You will: 1. Create a React app locally 2. Initialize an Amplify backend and add Auth (Cognito) 3. Push the backend to AWS 4. Commit the project to GitHub 5. Connect the repo to Amplify Hosting and deploy 6. Validate authentication and hosting 7. Clean up resources to avoid ongoing costs

Step 1: Create a React app (Vite)

Expected outcome: You have a working local React app running on your machine.

1) Create the app:

mkdir amplify-react-auth-lab
cd amplify-react-auth-lab
npm create vite@latest . -- --template react
npm install
npm run dev

2) Open the local URL shown in your terminal (commonly http://localhost:5173).

If you see the default Vite + React page, you’re ready.

Step 2: Install Amplify libraries and UI components

Expected outcome: Your project includes AWS Amplify client libraries and Amplify UI React components.

Install dependencies:

npm install aws-amplify @aws-amplify/ui-react

Step 3: Install and configure the Amplify CLI (if not installed)

Expected outcome: You can run amplify commands from your terminal.

Install the Amplify CLI:

npm install -g @aws-amplify/cli
amplify --version

Configure credentials (choose one approach):

If you use AWS SSO or an enterprise setup, follow your organization’s standard auth approach.
If using access keys, use aws configure (from AWS CLI) with an IAM user that has required permissions.

For exact, current setup steps, verify the official docs for your environment: https://docs.amplify.aws/

Step 4: Initialize an Amplify backend in the project

Expected outcome: An amplify/ directory is created and the project is connected to an AWS environment.

Run:

amplify init

You will be prompted for: – Project name (e.g., amplifyreactauthlab) – Environment name (e.g., dev) – Default editor – App type (JavaScript) – Framework (React) – Source directory (src) – Build directory (dist for Vite) – Start command (npm run dev) – Build command (npm run build)

Important for Vite: – Build output is typically dist (not build like older Create React App).

If you’re unsure, confirm by running:

npm run build
ls -la

You should see a dist/ folder after build.

Step 5: Add Authentication (Amazon Cognito)

Expected outcome: Amplify config is updated to include an Auth category, ready to deploy.

Run:

amplify add auth

Choose a setup that is easy for a lab: – “Default configuration” is usually the fastest path for a basic sign-in/sign-up experience.

You may be asked: – Whether to enable sign-in with email/username – MFA settings – Advanced settings

For a low-complexity lab, keep defaults unless your organization requires stronger settings.

Step 6: Push backend resources to AWS

Expected outcome: AWS resources (including Cognito) are created in your AWS account, and your app gets an aws-exports configuration file.

Run:

amplify push

Review the proposed changes. Confirm to proceed.

After completion, you should see an output file created, commonly: – src/aws-exports.js (common in many setups)

Verify it exists:

ls -la src | grep aws-exports

If you do not see it, check Amplify CLI output and verify the current doc for where outputs are written in your workflow.

Step 7: Update the React app to use Amplify Auth UI

Expected outcome: The app shows a hosted authentication UI (sign up / sign in), and after login displays your app content.

1) Edit src/main.jsx (or src/main.tsx if using TypeScript template). Replace the file contents with the following example:

import React from 'react'
import ReactDOM from 'react-dom/client'
import App from './App.jsx'

import { Amplify } from 'aws-amplify'
import awsExports from './aws-exports'

import '@aws-amplify/ui-react/styles.css'
import { Authenticator } from '@aws-amplify/ui-react'

Amplify.configure(awsExports)

ReactDOM.createRoot(document.getElementById('root')).render(
  <React.StrictMode>
    <Authenticator>
      {({ signOut, user }) => (
        <div style={{ padding: 20, fontFamily: 'system-ui, sans-serif' }}>
          <header style={{ display: 'flex', justifyContent: 'space-between', alignItems: 'center' }}>
            <h2>Amplify Auth Lab</h2>
            <button onClick={signOut}>Sign out</button>
          </header>

          <p>
            Signed in as: <strong>{user?.username}</strong>
          </p>

          <App />
        </div>
      )}
    </Authenticator>
  </React.StrictMode>
)

2) Optionally edit src/App.jsx to be simple:

export default function App() {
  return (
    <div>
      <h3>Welcome!</h3>
      <p>This app is hosted on AWS Amplify Hosting and uses Amazon Cognito for authentication.</p>
    </div>
  )
}

3) Run locally:

npm run dev

You should see an authentication screen. Create a test user and sign in.

Step 8: Create a GitHub repository and push code

Expected outcome: Your project is in GitHub and ready to connect to Amplify Hosting.

1) Initialize git and commit:

git init
git add .
git commit -m "Initial Amplify React auth lab"

2) Create a new GitHub repo (private or public) named amplify-react-auth-lab.

3) Add remote and push:

git branch -M main
git remote add origin https://github.com/<YOUR_GITHUB_USER>/amplify-react-auth-lab.git
git push -u origin main

Step 9: Deploy with AWS Amplify Hosting (Console)

Expected outcome: Amplify builds and deploys your app, giving you a public HTTPS URL.

1) Open the AWS Amplify console: – https://console.aws.amazon.com/amplify/

2) Choose Create new app → Host web app.

3) Select GitHub and authorize access to your repo.

4) Choose the repository and branch (main).

5) Build settings: – Amplify often detects frameworks automatically. – Confirm build output is dist for Vite. – If needed, edit build settings.

A typical build spec for Vite looks like:

# Build settings are usually configured in the Amplify console UI.
# If you manage an amplify.yml, ensure artifacts baseDirectory is "dist".

If an amplify.yml is used, ensure it matches your tooling. (Amplify may generate this for you in the console flow.)

6) Click Save and deploy.

Watch the build logs. A first build usually takes longer.

Step 10: Configure SPA rewrites (if needed)

Expected outcome: Refreshing deep links (e.g., /dashboard) does not return 404.

For single-page apps with client-side routing, configure a rewrite rule in Amplify Hosting: – Source: </^((?!\.).)*$/> (pattern varies) – Target: /index.html – Status: 200 (Rewrite)

Exact rewrite patterns depend on your routing needs. Verify the official Amplify Hosting SPA redirect guidance: – https://docs.aws.amazon.com/amplify/latest/userguide/redirects.html (verify current URL/guide location)

Validation

Use this checklist:

1) Hosting URL works – In Amplify console, open the deployed URL. – You should see the authentication UI.

2) Sign up / sign in works – Create a new user and sign in. – You should see “Signed in as: …” plus your App content.

3) Sign out works – Click “Sign out” and confirm you return to the sign-in screen.

4) Deployments are automatic – Make a small UI change, commit, and push:

# Example: edit App.jsx text
git add .
git commit -m "Update welcome text"
git push

Confirm Amplify triggers a new build and the site updates.

Troubleshooting

Issue: Build fails with “dist not found” – Cause: build output directory mismatch. – Fix: – Ensure you’re using Vite and output is dist/ – Confirm Amplify build settings artifacts directory is dist

Issue: aws-exports.js missing – Cause: backend not pushed or output path differs by workflow. – Fix: – Re-run amplify push – Check CLI output for where config was written – Verify docs for your Amplify workflow generation

Issue: CORS / auth token errors when calling APIs (future expansion) – Cause: backend auth modes or misconfigured endpoints. – Fix: – Confirm your Amplify configuration and that you’re signed in – Use the browser network console to inspect failing calls – Review AppSync/API Gateway auth configuration

Issue: Sign-up requires confirmation code but email is not received – Cause: email configuration or delivery issues (sandbox rules, spam filtering). – Fix: – Check Cognito user pool settings – Try a different email domain – Verify Cognito email/SMS configuration per region and account

Issue: amplify push fails with permission errors – Cause: IAM principal lacks permissions. – Fix: – Use a role/user with required permissions for CloudFormation, Cognito, IAM, etc. – In enterprises, request a standard “Amplify deployment role” from platform/security teams

Cleanup

To avoid ongoing costs, delete both backend and hosting resources.

1) Delete Amplify backend resources created by CLI:

amplify delete

Confirm when prompted. This typically removes CloudFormation stacks and resources created by Amplify for this environment.

2) Delete the Amplify Hosting app: – Amplify Console → your app → App settings → General → Delete app

3) (Optional) Delete GitHub repo if no longer needed.

4) Verify deletions: – AWS CloudFormation: confirm the stacks are removed – Amazon Cognito: confirm the user pool is deleted – AWS Amplify console: app removed

If deletion fails due to dependencies (e.g., S3 buckets not empty), follow the error message guidance, empty the bucket if needed, then retry. Always follow your organization’s data retention policy before deleting.

11. Best Practices

Architecture best practices

Use a clear separation of frontend hosting and backend services:
Frontend: Amplify Hosting (CDN + build pipeline)
Backend: Cognito/AppSync/API Gateway/Lambda/DynamoDB/S3 as needed
Design for multiple environments (dev/stage/prod):
Separate AWS accounts for strong isolation if possible
At minimum, separate branches and backend environments
Prefer stateless frontend: store state in APIs/databases, not in the hosting layer.

IAM/security best practices

Use least privilege IAM roles for:
Developers (read-only in prod)
CI/CD deployment roles
Break-glass admin access (audited)
Protect production with:
MFA on privileged IAM principals
SCP guardrails (AWS Organizations) where appropriate
Avoid embedding secrets in frontend code or build logs.

Cost best practices

Reduce build minutes:
Enable caching
Avoid unnecessary installs/tests in production builds
Manage preview environments:
Limit PR previews to active repos
Delete stale branches
Optimize content:
Compress images and use modern formats
Use caching headers appropriately (verify hosting header support)

Performance best practices

Keep bundles small:
Code splitting, lazy loading
Analyze bundle size in CI
Use CDN caching correctly:
Immutable hashes for static assets
Conservative caching for index.html if you need rapid rollouts
Monitor real-user performance (RUM) using your preferred tooling (AWS or third-party).

Reliability best practices

Use rollbacks:
Keep deployments reproducible and rollback-friendly
Avoid single points of failure in backend:
DynamoDB design for access patterns
Lambda timeouts and retries tuned properly
Use multi-region approaches only when justified; they increase complexity.

Operations best practices

Standardize:
Naming conventions for apps/branches/environments
Tagging for cost allocation
Implement alerting:
Budget alarms
CloudWatch alarms for backend error rates/latency
Centralize logs where feasible and compliant.

Governance/tagging/naming best practices

Tag consistently:
Application, Environment, Owner, CostCenter, DataClassification
Use predictable environment names:
dev, staging, prod
Maintain an inventory of Amplify apps and associated domains.

12. Security Considerations

Identity and access model

IAM controls administrative access (who can deploy, configure domains, edit builds).
Cognito (commonly) controls end-user identities.
Use separate roles for:
Build/deploy operations
Runtime backend access
Human admin access (limited, audited)

Encryption

In transit: HTTPS for hosted apps; TLS for APIs.
At rest: underlying services (S3, DynamoDB, Cognito) support encryption at rest.
Confirm encryption settings on each dependent service; don’t assume defaults meet your compliance needs.

Network exposure

Amplify-hosted frontends are typically public internet endpoints.
Backend endpoints (AppSync/API Gateway) are typically public but protected by auth.
If you require private-only access (no public endpoints), Amplify Hosting may not be the right fit without additional architecture.

Secrets handling

Do not place secrets in:
Browser code
Public environment variables
Git repos
For build-time secrets, evaluate:
Amplify environment variables (treat as sensitive)
AWS Secrets Manager / SSM Parameter Store for backend secrets (and fetch them server-side)
Never store long-lived AWS keys in frontend apps.

Audit/logging

Enable and review:
AWS CloudTrail for API actions
Build/deploy logs in Amplify
CloudWatch logs for Lambda and APIs
For regulated environments, ensure log retention meets policy.

Compliance considerations

Data residency: backend resources are regional; pick region deliberately.
PII: classify data stored in Cognito attributes, DynamoDB, and S3.
MFA: decide on MFA requirements for end users and admin users.
For strict compliance (PCI/HIPAA/etc.), verify each service’s compliance eligibility in AWS Artifact and service-specific compliance documentation.

Common security mistakes

Misconfigured S3 buckets (public read/write)
Overly permissive IAM roles created for convenience
Shipping secrets in .env files to the browser bundle
Weak Cognito policies (no MFA, weak password policy) for sensitive apps
Lack of environment separation (dev credentials used in prod)

Secure deployment recommendations

Use separate AWS accounts for prod.
Restrict who can connect GitHub repos and deploy to production branches.
Use protected branches and required reviews in GitHub.
Consider adding security headers (CSP, HSTS) via hosting header rules where supported—test carefully.

13. Limitations and Gotchas

Because AWS Amplify spans hosting, developer tooling, and integrations, limitations can appear at multiple layers.

Common limitations (verify current specifics)

Advanced CDN controls: You may not get full CloudFront-level configurability directly through Amplify Hosting UI.
Private networking/VPC: Hosting is managed and internet-facing; private-only hosting patterns require different architectures.
SSR and framework support nuances: SSR support can be framework/version dependent. Always verify your exact framework/version in official hosting docs.
Build environment constraints: Build images, Node versions, and timeouts may be constrained; long builds can fail.
Observability scope: Amplify provides build/deploy logs, but runtime observability depends on underlying services.
Environment sprawl: Branch previews and multiple environments can multiply backend stacks and cost/complexity.

Quotas and limits

Amplify apps/branches/build concurrency limits exist.
Cognito limits exist (user pools, clients, etc.).
API service limits (AppSync, API Gateway) and Lambda concurrency limits apply. Check Service Quotas and service docs for current numbers.

Regional constraints

Not all features are available in all AWS regions.
Custom domain and certificate flows may vary by region. Always verify availability in your chosen region.

Pricing surprises

CI build minutes can add up quickly in active repos.
Data transfer out (especially large assets) can be significant at scale.
SMS-based MFA can be expensive depending on volume and destination.

Compatibility issues

Some build systems require custom configuration (monorepos, pnpm, native dependencies).
SPA routing requires correct rewrites; misconfiguration yields 404s on refresh.

Migration challenges

Moving away from Amplify Hosting to bespoke CloudFront/S3/CodePipeline is possible but requires re-implementing pipeline, rewrites, and domain mapping.
If you use Amplify-provisioned backend stacks, you’ll need a plan to transition infrastructure ownership cleanly.

16. FAQ

1) Is AWS Amplify only for web apps?
No. AWS Amplify targets Frontend web and mobile. It includes hosting for web apps and client libraries/UI for web and mobile platforms. Specific capabilities vary by platform—verify the docs for iOS/Android/Flutter support.

2) What is the difference between AWS Amplify and Amazon CloudFront + S3?
CloudFront + S3 is a DIY approach with maximum control. AWS Amplify Hosting provides a managed CI/CD and hosting workflow that often uses CloudFront under the hood, but with fewer low-level knobs.

3) Do I need to use Amplify Studio or the CLI?
Not necessarily. You can use Amplify Hosting alone. Studio/CLI are used when you want Amplify-managed backend workflows. Choose the workflow that matches your team and governance needs.

4) Does Amplify create AWS resources in my account?
Yes—when you enable backend features, AWS Amplify tooling provisions resources (often via CloudFormation). You are responsible for their security and cost.

5) Can I use my own CI/CD and still use Amplify Hosting?
Amplify Hosting is designed around managed CI/CD from a Git repo. If you need a fully custom CI/CD, you may prefer S3/CloudFront with CodePipeline/CodeBuild or another hosting approach.

6) How do custom domains work in Amplify Hosting?
You map a domain (often via Route 53 or external DNS). Amplify typically helps with certificate provisioning/validation. Exact steps depend on domain provider and region—verify hosting docs.

7) Is AWS Amplify suitable for regulated workloads?
It can be, depending on requirements. You must evaluate IAM controls, logging, encryption, and underlying service compliance. For strict regulatory needs, confirm each service’s compliance eligibility.

8) Where are build logs stored?
Build logs are accessible in the Amplify console. For long-term retention and centralized logging, evaluate exporting or using other mechanisms—verify current options in docs.

9) Can I attach AWS WAF to an Amplify-hosted app?
Amplify Hosting typically uses a CDN distribution. Direct WAF attachment may not be exposed as a simple toggle in all configurations. Verify current Amplify Hosting features and recommended patterns in official docs.

10) How do I do environment-specific configuration?
Common approaches include branch-based deployments, environment variables, and separate backend environments/accounts. Avoid putting secrets in frontend environment variables.

11) Does Amplify support SSR frameworks like Next.js?
Amplify Hosting supports certain SSR patterns, but support depends on framework versions and build settings. Always verify in the official hosting documentation for your framework.

12) What are the most common causes of Amplify Hosting build failures?
Output directory mismatch (dist vs build), Node version mismatches, missing environment variables, monorepo misconfiguration, and dependency installation issues.

13) Can I use Amplify with an existing Cognito user pool?
Often yes, but the workflow depends on how you manage backend resources and configuration. Verify the current best practice in Amplify docs.

14) Do I pay for Cognito if I use Amplify Auth?
Yes. Cognito has its own pricing model. Amplify libraries are client-side; backend services you use are billed separately.

15) How do I avoid surprise costs?
Set AWS Budgets, limit preview environments, optimize build times and asset size, and monitor data transfer and backend consumption.

23. Summary

AWS Amplify is AWS’s developer-focused platform for Frontend web and mobile application delivery, combining managed hosting/CI/CD (Amplify Hosting) with tools and libraries to integrate common backend capabilities like authentication, APIs, and storage.

It matters because it reduces the time and operational effort required to deploy frontend apps reliably, while leveraging AWS-native services for scaling and security. Cost is primarily driven by build minutes, hosting/storage, and data transfer, plus the usage of backend services like Cognito, S3, Lambda, AppSync, and DynamoDB. Security success depends on disciplined IAM least privilege, safe secrets handling, correct auth configuration, and strong logging/auditing practices.

Use AWS Amplify when you want a practical, AWS-native “paved road” for shipping frontend apps with optional serverless backends. If you need maximum control over edge/CDN settings or strict private networking, consider building directly with CloudFront/S3 and custom CI/CD.

Next step: follow the official AWS Amplify documentation and expand this lab by adding an API (AppSync or API Gateway) and storage with per-user permissions: – https://docs.amplify.aws/
