Which combination of AWS services can the application use to meet these requirements?

Explanations:

Amazon SQS is a message queuing service that enables asynchronous communication between decoupled components, making it ideal for event-driven architectures in microservices.

AWS Lambda is a serverless compute service that can run event-driven functions, making it suitable for a microservices-based application that responds to events in real time.

AWS Migration Hub is a tool for tracking the migration status of applications but does not support event-driven or microservices-based architectures.

AWS AppSync is used for building APIs with GraphQL, but it is not specifically designed for event-driven or asynchronous processing required by microservices architectures.

AWS Application Migration Service assists in migrating applications to AWS but does not directly support event-driven, microservices-based architectures.
