Which AWS service gives users the ability to develop loosely coupled microservices and improve service-to-service communication?
Explanation:
Amazon EventBridge is the correct answer because it is an event bus service that enables developers to build event-driven applications and microservices. It facilitates loose coupling between services by allowing them to communicate through events rather than direct API calls. This improves service-to-service communication by decoupling services and enabling them to react to events from various AWS services, SaaS applications, and custom applications without needing to know about each other directly.
