What are the best practices for using Lambda layers?

When using Lambda layers, consider the following best practices: keep layers small, version your layers, and avoid including unnecessary dependencies.

Why is it important to keep layers small?

Keeping layers small reduces cold start times and improves performance, making your Lambda functions more efficient.

How do I version my Lambda layers?

You can version your Lambda layers by creating a new layer version each time you update the code or dependencies, and then referencing the specific version in your Lambda function.

Can I use multiple layers in a single Lambda function?

Yes, you can use up to five layers in a single Lambda function, allowing you to modularize your code and share common dependencies.

What are some common use cases for Lambda layers?

Common use cases include sharing libraries, managing dependencies, and packaging custom runtimes across multiple Lambda functions.
