Identify deprecated Lambda functions with Datadog

AWS Lambda supports various programming languages and runtimes. However, when a runtime is deprecated, users must decide on an alternative approach to ensure their functions continue running as expected. The three main options are packaging Lambda functions as container images, migrating to custom runtimes, or rewriting all code in a supported language. Datadog can help identify which Lambda functions are using deprecated runtimes and provide warnings within the Serverless page. Most users prefer packaging their Lambda functions as container images due to its benefits such as easy portability across environments and less operational overhead compared to custom runtimes or rewriting code. However, there are trade-offs to consider, like increased complexity in vulnerability management for container images.
