# cloud-infrastructure Infrastructure-as-code with Terraform and AWS CDK, cloud architecture patterns, cost optimisation, and multi-region deployment design. ## When to use - Write Terraform to provision an RDS PostgreSQL instance with a read replica - Design a multi-AZ VPC with public and private subnets for a 3-tier app - Convert our Terraform S3 + CloudFront setup to AWS CDK TypeScript - Our AWS bill doubled last month — what should we look at? - Design a disaster-recovery architecture with RPO < 1 hour across two regions - Write a Terraform module for an EKS cluster with managed node groups - Set up an IAM role with least-privilege access for a Lambda reading from S3 - Architect a serverless API: API Gateway + Lambda + DynamoDB ## When NOT to use - Write a Kubernetes Deployment and Service for our FastAPI app — K8s application manifests — not infrastructure provisioning - Set up a GitHub Actions workflow for blue-green deploys — CI/CD pipeline — separate concern - Debug why our Docker container crashes on startup — App-layer debugging — not infra - Write the FastAPI code for our API endpoint — Application code — not infrastructure ## Anti-patterns ### Symptom Invoking this skill for tasks outside its scope — e.g., infrastructure concerns when the request is about application code, or vice versa. ### Problem Scope mismatch wastes context and produces advice tuned for the wrong domain. A database schema skill answering a connection-pooling question gives schema advi
