Real Use Cases for Using AWS Lambda for Infrastructure Tasks
summary
Concrete examples of using AWS Lambda for infrastructure: Jenkins event-driven Lambdas that coordinate jobs and push summaries to SQS; a Lambda that builds and updates heavy base Docker images on a cheap t2 instance; and small Lambdas that collect Android test metrics and shut down idle EC2 instances. The talk covers custom runtimes and Go support, development tools (SAM/docker for local testing and Terraform for deployments), and measured tradeoffs such as cold-start times (~1.5s for Go vs 12–15s for Java) and a rewrite that cut costs roughly in half to about $3.
