A developer is building a serverless application that is based on AWS Lambd

a. The developer initializes the AWS software development kit (SDK) outside of the Lambda handcar function.

What is the PRIMARY benefit of this action?

AImproves legibility and systolic convention

BTakes advantage of runtime environment reuse

CProvides better error handling

DCreates a new SDK instance for each invocation

Show Suggested Answer

Suggested Answer: B

This benefit occurs when initializing the AWS SDK outside of the Lambda handler function because it allows the SDK instance to be reused across multiple invocations of the same function. This can improve performance and reduce latency by avoiding unnecessary initialization overhead. If the SDK is initialized inside the handler function, it will create a new SDK instance for each invocation, which can increase memory usage and execution time.

But wouldn't taking advantage of runtime environment reuse be more efficient?

I agree with Ernest. Initializing the SDK outside the Lambda handler function allows the runtime environment to be reused, which is a big performance boost for serverless apps.
