To update a function, you need to migrate it to a supported runtime. Phase 2 - you can no longer create or update functions that use the runtime. Note that functions that use a deprecated runtime are no longer eligible for technical This includes updating the runtime, and rolling back to the previous You can no longer create functions that use the runtime, but you canĬontinue to update existing functions. Phase 1 - Lambda no longer applies security When security updates are no longer available for a component of a runtime, Lambda deprecates theĭeprecation (end of support) for a runtime occurs in two phases. zip file archives are built around aĬombination of operating system, programming language, and software libraries that are subject to maintenance and Lambda keeps managed runtimes up to date with patches and support for minor version releases. General availability (GA) release of the Ruby 3.2 runtime. Lambda will support the Ruby 2.7 runtime for at least 6 months after the *The deprecation date for Ruby 2.7 above is an estimate. The underlying execution environment providesĪdditional libraries and environment variables that you can access from The runtime is paired with one of the Amazon Linux distributions. To change the runtime, you can update your function's configuration. zip file archive for the deployment package, you choose a runtime when you create the function. To change the runtime, you create a new container image. You choose a runtime and the Linux distribution when you create the container image. Since AWS Lambda cannot guarantee backward compatibility between major versions, this is a customer-driven operation.įor a function defined as a container image, To configure a function to use a new major language version, you need to change the runtime identifier. You can use runtimes that Lambda provides, or build your own.Įach major programming language release has a separate runtime, with a unique runtime identifier, such as python3.10 or nodejs18.x. A runtime provides a language-specific environment that relays invocation events, context information, and responses between Lambda and the function. Lambda supports multiple languages through the use of runtimes.
