What are AWS Lambda Layers?
AWS Lambda Layers is a distribution mechanism for libraries, custom runtimes, and other function dependencies. Layers can be used to separate different components of an application, By separating these components, you can reuse the same code (in the form of layers) across multiple AWS lambda functions or even other AWS accounts.
For instance, we can separate our business logic and the application dependencies, so that our application will look organized, the common codes (layers) can be reused across other lambda functions, and we can even share the layers of other lambda functions which require the same dependencies.
How To Use AWS Lambda Layers for Code Reuse and Organization?
AWS lambda is an AWS service that works with Serverless Architecture, The infrastructure management is automatically managed by the AWS. It facilitates the developers to focus on the Code development completely. AWS Lambda Layers extends the core functionalities of the AWS Lambda functions through an efficient approach for managing dependencies and reusability of code. Mainly lambda layers allow the users to separate and externalize the dependencies making the efficient code organization bringing develop enhancement in the workflow.
