Cloud Infrastructure
Design and provision cloud infrastructure with AWS-primary patterns and cloud-agnostic naming for portability.
Decision Framework
New service/workload?
├── Stateless, event-driven, <15min → Serverless (Lambda + API GW)
├── Long-running, stateful, predictable → Containers (ECS Fargate)
├── Kubernetes-native, multi-cloud → Orchestration (EKS)
└── Static content, CDN → Storage (S3 + CloudFront)
Database needs?
├── Key-value, <1ms, scale-to-zero → DynamoDB
├── Relational, complex queries → RDS/Aurora
├── Document store, flexible schema → DocumentDB
└── Cache, sessions, pub/sub → ElastiCache (Redis)
IaC approach?
├── AWS-only, type-safe → CDK (TypeScript)
├── Multi-cloud, declarative → Terraform
└── Simple, YAML → CloudFormation
When NOT to Use
- CI/CD pipelines: Use
ci-cd skill for pipeline config (CodePipeline, GitHub Actions)
- Database schema design: Use
database-design skill for schema/migrations/queries
- Application-level monitoring: Use
observability skill for application metrics/logs/traces
