Aws Amplify

AWS Amplify is AWS's answer to Vercel/Netlify — Git-connected hosting with automatic CI/CD, preview deployments per branch, and optional backend provisioning (Cognito, AppSync, S3, Lambda) via the Amplify CLI. For agents: the REST API creates Amplify apps connected to Git repos, manages branches (main + preview branches), triggers manual deployments, manages environment variables (config vars), and retrieves deployment status. Free tier is generous for small to medium applications. Confidence is docs-derived.

Amplify API via boto3 (Python). amplify.create_app(name, repository, oauthToken, platform="WEB") creates app connected to GitHub. amplify.create_branch(appId, branchName, environmentVariables={KEY: "value"}) creates a branch. amplify.start_deployment(appId, branchName) triggers manual deployment. amplify.get_app(appId) retrieves app details. amplify.list_apps() lists all Amplify apps. amplify.list_branches(appId) lists branches. amplify.list_jobs(appId, branchName) lists deployment jobs. amplify.get_job(appId, branchName, jobId) retrieves job status. amplify.update_app(appId, environmentVariables={...}) updates app-level env vars. amplify.delete_branch(appId, branchName) removes a branch. Webhooks: amplify.create_webhook(appId, branchName) creates deploy webhook URL.

IAM-based auth: SigV4 via boto3. IAM roles: amplify:CreateApp, amplify:CreateBranch, amplify:StartDeployment, amplify:GetJob. HTTPS enforced. No OAuth2. GitHub OAuth token: required for repository connection (store in Secrets Manager, not IAM). Build settings: buildspec.yml or amplify.yml in repository root defines build commands. Backend environments: AWS CDK/CloudFormation managed — separate from hosting management.

Deployment: async — poll get_job until SUCCEED/FAILED. Build logs: available via amplify.get_job (logUrl in job details). Preview branches: auto-created for pull requests (configure in App settings). Custom domains: amplify.create_domain_association for custom domain configuration. Amplify uptime at status.aws.amazon.com. Free tier: 1000 build minutes/month — adequate for low-frequency deployments. Build cache: Amplify caches node_modules between builds — configure in buildspec for custom cache paths. SSR (Server-Side Rendering): Next.js SSR support via Amplify Hosting — different compute model than static.

docs.aws.amazon.com/amplify/latest/APIReference covers REST API reference, CI/CD guide, custom domain setup, and backend provisioning documentation. Getting started: AWS free tier, connect GitHub repo via Console or boto3 — first deployment in under 10 minutes. boto3 amplify client: pip install boto3. Amplify CLI: npm install -g @aws-amplify/cli for backend provisioning. Community via AWS re:Post and Stack Overflow (aws-amplify tag). Good documentation for a multi-faceted platform.
