A company wants to re-architect a large-scale web application to a serverless microservices architecture. The application uses Amazon EC2 instances and is written in Python. The company selected one component of the web application to test as a microservice. The component supports hundreds of requests each second. The company wants to create and test the microservice on an AWS solution that supports Python. The solution must also scale automatically and require minimal infrastructure and minimal operational support. Which solution will meet these requirements?
