Lambda Execution Environment Reuse


Lambda Execution Environment Reuse

Each lambda call can get a new execution environment.

The environment manages the resources that run your function.

You can reuse the existing environment when it is repeated.

Reusing execution environments increases function execution speed.

Lambda Function Design Best Practices

Limit the number of variables or objects calls.

Make sure to check for existing connections before creating new ones.

Check local data storage for previously saved data.

Ensure that background processes are finished before exiting the function.
