Identify deprecated Lambda functions with Datadog

AWS Lambda supports nearly any programming language via serverless functions. When AWS deprecates a runtime, developers need to choose a course of action to keep their Lambda functions running. Options include packaging functions as container images, migrating to custom runtimes, or rewriting code in a supported language. Datadog helps identify functions using deprecated runtimes and provides warnings with contextual information, helping manage the transition smoothly. Packaging functions as container images has benefits like ease of portability and reduced operational overhead but also has tradeoffs such as complexity in vulnerability maintenance.
