Question

A company's application has an AWS Lambda function that processes messages from IoT devices. The company wants to monitor the Lambda function to ensure that the Lambda function is meeting its required service level agreement (SLA). A developer must implement a solution to determine the application's throughput in near real time. The throughput must be based on the number of messages that the Lambda function receives and processes in a given time period. The Lambda function performs initialization and post-processing steps that must not factor into the throughput measurement. What should the developer do to meet these requirements?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Modify the application to publish custom Amazon CloudWatch metrics when the Lambda function receives and processes each message. Use the metrics to calculate the throughput. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon CloudWatch collects metrics, logs and alarms to monitor and react to operational health. This option meets the real-time / low-latency performance requirement.
