Messaging facilitates communication between different parts of distributed systems and applications. It eliminates the need to understand the application’s architecture to exchange messages. There are many open-source messaging broker tools that can be used to create messaging applications.
Today we will be examining Amazon MQ, one of AWS Managed Message Broker services. Learn about Amazon MQ and its benefits. Also, learn about its advantages over Amazon SQS. We will also show you how to use it in an app.
Introduction to Amazon MQ
Amazon MQ is a managed service offered by AWS. It acts as a message broker for Apache ActiveMQ and RabbitMQ. Amazon MQ is a managed service. This reduces the operational responsibilities of setting up, maintaining and provisioning message brokers. Amazon MQ allows one to quickly connect to AWS and does not require rewriting code. It can also connect to existing applications using industry-standard protocols and APIs. Amazon MQ is easy to set up and supports multiple languages.
What is Amazon MQ Broker?
We can create a message broker according to your requirements. A broker can be either a single-instance or active/standby broker.
A Single Instance Broker is one broker in one availability. It communicates with AWS storage locations and the application. It is used to develop and test.
Two brokers are available in two availability zones to ensure high availability. It can communicate with the application and share storage locations. It can also be used to perform automatic failover. For both modes, Amazon MQ provides data replication across AZs.
Why ActiveMQ? Why not a database to store messages in?
Yes, the database can be used to store and process messages. However, communication between two applications should occur once the message has been received. Once it is processed, it should be deleted. It will work for a few messages and not affect the database’s performance. It can cause database performance problems if we need to handle thousands of messages from these applications.
Amazon MQ is a message broker service that Apache ActiveMQ uses. It can be used to handle this use-case. It will manage ActiveMQ brokers’ maintenance and optimize overhead. It allows consumers to push messages to them, rather than polling the consumer for a new message. Messaging facilitates communication among distinct parts of distributed systems and applications. It eliminates the need for the application to swap messages. This reduces the latency required to process new messages.
Amazon MQ: Benefits
Application Integration: It allows you to integrate different operating systems and languages to communicate with one another.
Reliability: There is no need to have both producers and consumers available at the same moment. Queue to handle any number of requests at any time.
Asynchronous allows an application to send a message to another and then continue with other tasks, rather than waiting for a reply.
Decoupled: Because the queue is between the application and the communication, any failure of one system will not impact other applications.
Cost reduction: You only pay for the storage or broker instance that you use.

Connecting to Java Application and creating a Broker
We will create two components, a Producer as well as a Consumer. The Producer will click on the Broker to create a queue, send a message and then the
