SAA-C03 Q300 · Serverless

Question

A genomics research company is designing a scalable architecture for a loosely coupled workload. Tasks in the workload are independent and can be processed in parallel. The architecture needs to minimize management overhead and provide automatic scaling based on demand. Which solution will meet these requirements?

Accepted Answer

AWS Lambda is the ideal solution because it satisfies every requirement stated in the question:

1. **Loosely coupled workload**: Lambda functions are inherently decoupled — each function invocation is independent. You can combine Lambda with Amazon SQS or Amazon EventBridge for event-driven, loosely coupled processing.

2. **Independent tasks processed in parallel**: Lambda automatically scales out horizontally. Each task triggers a separate function invocation, and Lambda can run thousands of concurrent executions simultaneously — perfect for embarrassingly parallel workloads.

3. **Minimize management overhead**: Lambda is fully serverless — no servers to provision, patch, or manage. No OS updates, no capacity planning, no cluster management. AWS handles all infrastructure operations.
