Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 220 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C03
Question #: 220
Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A solutions architect is designing a new API using Amazon API Gateway that will receive requests from users. The volume of requests is highly variable; several hours can pass without receiving a single request. The data processing will take place asynchronously, but should be completed within a few seconds after a request is made.

Which compute service should the solutions architect have the API invoke to deliver the requirements at the lowest cost?

  • A. An AWS Glue job
  • B. An AWS Lambda function
  • C. A containerized service hosted in Amazon Elastic Kubernetes Service (Amazon EKS)
  • D. A containerized service hosted in Amazon ECS with Amazon EC2

B is the correct answer. API Gateway + Lambda is the perfect solution for modern applications with serverless architecture.

Selected Answer: B
Lambda is a serverless compute service that can be triggered by API Gateway to process requests asynchronously. It automatically scales based on the incoming request volume and allows for cost optimization by charging only for the actual compute time used to process the requests. A. Glue is a fully managed ETL service. It is designed for data processing and transformation tasks rather than serving API requests. It may not be suitable for handling variable request volumes and delivering responses within a few seconds. C. While EKS provides scalability and flexibility, it may introduce additional complexity and overhead for managing and scaling the infrastructure for handling variable API request volumes. D. Similar to the previous option, using ECS with EC2 would require additional effort for infrastructure management and scaling, which may not be necessary for handling intermittent and variable API request volumes.
