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

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

Screaming Lambda

data processing should be completed within a few seconds = An AWS Lambda function

B. An AWS Lambda function

lambda is expensive than running ECS on EC2

Lambda all the way.

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.

Option B meets the requirements.

Lambda !
