Amazon Messaging Queue [AMQ]

Amazon MQ is a fully managed service that provisions and manages open source message brokers like RabbitMQ and Apache ActiveMQ for you. Amazon MQ for RabbitMQ manages both individual and clustered message brokers and handles tasks like provisioning the infrastructure, setting up the broker, and updating the software.

CargoDocs API uses Amazon MQ which now supports Rabbit MQ over which the actual message queue was built. Amazon MQ is a managed message broker service that makes it easy to migrate to a message broker in the cloud. A message broker allows software applications and components to communicate using various programming languages, operating systems, and formal messaging protocols.
