Aws Lambda

"Use when building AWS Lambda functions."

Trigger

Activate this skill when the user mentions:

• aws, lambda, serverless, functions workflows or issues
• Building, fixing, or optimizing aws lambda
• Questions about aws best practices

Core Concepts

• Infrastructure as Code (IaC)
• Well-Architected Framework
• Identity and access management
• Networking and security groups
• Cost optimization and tagging

Step-by-Step Workflow

1. Design — Architecture review against WAF pillars
   • Expected: Approved architecture diagram
2. Implement — IaC templates with least-privilege IAM
   • Expected: Reviewable version-controlled infra
3. Validate — Security scan, cost estimate, plan review
   • Expected: Clean plan within budget
4. Deploy — Apply with change management
   • Expected: Deployed infrastructure matches plan
5. Monitor — Alarms, dashboards, cost alerts
   • Expected: Full observability and cost allocation

Tools & Technologies

• Terraform/Pulumi
• Cloud-native IaC
• Security scanning
• Cost management

Best Practices

• Document decisions and rationale (ADRs, design docs, runbooks)
• Version everything - code, configs, data, and documentation
• Test incrementally; never claim passing without verification
• Respect domain-specific regulations and ethical standards
• Measure outcomes with meaningful metrics

Common Pitfalls

• Manual console changes → Configuration drift → All changes through IaC
• Over-privileged IAM → Blast radius risk → Least privilege by default
