AWS Lambda: From Curiosity to Production
summary
Practical recipe for taking AWS Lambda to production: use AWS CLI and boto3, develop in virtualenv, flatten dependencies into a zip or Docker-based AMI replica, and run tests inside CI by executing the same image; deploy by creating immutable versions and pointing aliases to promote dev→stage→prod; store per-environment credentials encrypted in S3/KMS and use a canary lambda to validate VPC/network access; be aware of limits: 300s timeout, default 100 concurrency, and a real bill example of 1.4M invokes ≈ $0.08.
