Lambda Layers

PreviousConfiguring LambdaNext19_API_Gateway

Last updated 4 months ago

  • Additional libraries may be bundled and moved as a layer.

  • Lambda can have upto 5 layers per function, with maximum deployment size limit of 50 MB/layer.

  • The packages added in layers are available in /opt directory during invocations.

Custom Runtimes

  • Allows languages that are not officially supported by AWS to be used to develop and deploy on Lambda.

  • C++ rutimes is one such example. Some of the common ones can be found .

Externalize Dependencies

  • Dependencies which we use in our lambda code may not change often compare to our application/lambda code. So in order to avoid reuploading dependencies which seldom changes, one can leverage the lambda layers.

  • As layers are externalized they can be reused across multiple function code.
