Which service is a managed message broker service that makes it easy to migrate to a message broker in the cloud?

• A. Amazon SQS
• B. Amazon MQ
• C. Amazon EventBridge
• D. AWS AppSync

Answer: (B)

Migrating to a cloud-based message broker is streamlined when you use a managed broker that supports standard broker protocols and APIs. Amazon MQ is a fully managed message broker service that runs popular open-source brokers such as Apache ActiveMQ and RabbitMQ. It handles provisioning, patching, failover, and backups, so teams can shift to the cloud without managing broker software themselves. Because it supports widely used protocols like JMS, AMQP, MQTT, STOMP, and OpenWire, existing applications can connect with little to no code changes, easing the migration path. In contrast, Amazon SQS is a simple queue service rather than a broker, EventBridge is an event bus for events, and AWS AppSync is a GraphQL API service, none of which are designed specifically as a managed broker with migration focus.
