A company needs to simultaneously process hundreds of requests from (CLF-C02)

Correct answer: A) Amazon Simple Queue Service (Amazon SQS) and AWS Lambda.
Amazon SQS (Simple Queue Service): SQS is a fully managed message queuing service that enables you to decouple and scale microservices, distributed systems, and serverless applications. With SQS, you can buffer requests from senders and receivers, allowing for asynchronous communication between different components of your system. This helps handle bursts of requests efficiently and ensures that requests are not lost if the processing system becomes overwhelmed.

AWS Lambda: Lambda is a serverless compute service that lets you run code without provisioning or managing servers. You can use Lambda to execute code in response to events, such as changes to data in Amazon S3 buckets, updates to Amazon DynamoDB tables, or messages arriving in SQS queues. By integrating SQS with Lambda, you can create event-driven processing pipelines. When SQS receives messages, it can trigger Lambda functions to process those messages, allowing for scalable and efficient processing of requests.

This combination provides a scalable, reliable, and operationally efficient solution for handling hundreds of requests from different users simultaneously, ensuring that requests are processed in a timely manner without overwhelming the system. Additionally, it aligns well with modern architectural principles such as decoupling, scalability, and serverless computing.
