Extensions are a new way for tools to more easily integrate deeply into the Lambda execution environment to control and participate in Lambda’s lifecycle.
You can use extensions to integrate your Lambda functions with your preferred monitoring, observability, security, and governance tools. You can choose from a broad set of tools provided by AWS Lambda partners or you can create your own Lambda extensions.
Extensions use the Extensions API, a new HTTP interface, to register for lifecycle events and get greater control during function initialization, invocation, and shutdown. They can also use environment variables to add options and tools to the runtime, or use wrapper scripts to customize the runtime startup behavior.
Note: an internal extension runs in the runtime process, and shares the same lifecycle as the runtime. An external extension runs as a separate process in the execution environment. The extension runs in parallel with the function's runtime. It is initialized before the function is invoked and continues to run after the function invocation is complete
