AWS Lambda supports a wide range of programming languages through serverless functions, but when a runtime is deprecated, developers must adapt to ensure their applications continue to function. Options include packaging functions as container images, migrating to custom runtimes, or rewriting code in a supported language. In practice, many Datadog customers have opted for container images, which offer portability and reduced operational overhead compared to custom runtimes or code rewriting. However, container images pose challenges in maintaining and inspecting for vulnerabilities. Datadog aids in managing this transition by identifying Lambda functions using deprecated runtimes, providing warnings and contextual information to facilitate decision-making on runtime updates.
