Question

A company has a small Python application that processes JSON documents and outputs the results to an on-premises SQL database. The application runs thousands of times each day. The company wants to move the application to the AWS Cloud. The company needs a highly available solution that maximizes scalability and minimizes operational overhead. Which solution will meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Place the JSON documents in an Amazon S3 bucket. Create an AWS Lambda function that runs the Python code to process the documents as they arrive in the S3 bucket. Store the results in an Amazon Aurora DB cluster. AWS Lambda runs code without provisioning servers and scales automatically, which minimizes operational overhead. Amazon S3 provides durable, scalable object storage that is fully managed. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
