Answer Description

The statement is correct because Amazon SNS is a managed service that coordinates the delivery of messages to subscribing endpoints or clients. When used with AWS Lambda, it triggers the execution of Lambda functions in response to messages, enabling asynchronous, event-driven processing which is a core concept in microservices architectures. This achieves the loose coupling of services, as each service can operate independently and is only invoked through events, enhancing scalability and reliability.
