Architectural patterns for serverless execution and orchestration.
🚀 Core Commands
Function Lifecycle
# List all functions with runtime and memory info aws lambda list-functions --query "Functions[].{Name:FunctionName,Runtime:Runtime,Memory:MemorySize}" --output table
# Invoke a function synchronously with payload aws lambda invoke --function-name --payload '{"key": "value"}' --cli-binary-format raw-in-base64-out response.json
Deployment & Configuration
# Update function code via ZIP aws lambda update-function-code --function-name --zip-file fileb://function.zip
# Update environment variables aws lambda update-function-configuration --function-name --environment "Variables={KEY=VALUE,ENV=PROD}"
Performance & Scaling
# Check concurrency limits and usage aws lambda get-account-settings --query "AccountLimit"
# Put provisioned concurrency (warm start optimization) aws lambda put-provisioned-concurrency-config --function-name --qualifier --provisioned-concurrent-executions 5
🧠 Best Practices
- Layer Management: Offload heavy dependencies (like FFmpeg or Chromium) into Lambda Layers to keep deployment packages small.
- Timeout Strategy: Set aggressive timeouts to prevent runaway costs from stuck executions.
- IAM Execution Role: Ensure the role has exactly the permissions needed for S3/DynamoDB access—no more.
- Monitoring: Use CloudWatch Insights to trace latencies and cold starts.
