Which solution will meet these requirements?
Increase the API Gateway throttling limit.
Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day.
Create an Amazon CloudWatch alarm to initiate a Lambda function as a target for the alarm at the beginning of each day.
Increase the Lambda function memory.
Explanations:
Increasing the API Gateway throttling limit does not address latency issues, which are related to Lambda cold starts and scalability.
Provisioned concurrency ensures that a specified number of Lambda instances are always pre-warmed, reducing latency due to cold starts.
A CloudWatch alarm would only trigger based on certain metrics or events; it does not directly solve cold start latency or scaling issues.
Increasing Lambda memory can improve performance for some workloads, but it does not directly address the cold start latency issue.
I estimate that the answer is:
Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day.
I suspect that the answer is:
Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day.
