Stacks

IPA stacks are CloudFormation-based infrastructure components that compose into deployable solutions. Each stack wraps one or more AWS services with security defaults, observability, and a consistent parameter interface.

Stacks fall into two lifecycle categories:

  • Prepare stacks are one-time prerequisites that persist across teardown and redeployment cycles. Deploy them once with /ipa.prepare.
  • Deploy stacks (tiers) are application infrastructure created and torn down with each pattern deployment via /ipa.deploy.

Deploy Stacks (Tiers)​

  • Frontend — S3 + CloudFront with Origin Access Control for static web hosting.
  • Backend — Lambda + API Gateway v2 + DynamoDB + CloudWatch for serverless APIs.
  • Queue — SQS + DLQ + worker Lambda + EventSourceMapping + DynamoDB + CloudWatch for event-driven processing.

Prepare Stacks​

  • Cognito — Cognito User Pool with OAuth 2.0 Hosted UI and OIDC endpoints for authentication.
  • ECR — Elastic Container Registry repository for Lambda container images.
  • CodePipeline — CodePipeline + CodeBuild for CI/CD automation.
  • CodeCommit — CodeCommit repository for source code management.
