Introduction

A message queue is used to store the data produced by various applications when there is a need to collect, process, or take action on a message. There is usually nothing more than simple messages here, such as requests, replies, error messages, or just basic information.

What is an Amazon MQ?

The Amazon message broker is an integrated Apache ActiveMQ and RabbitMQ service.

A messaging platform of industry standards is provided.

Supports management using standard tools, such as AWS Management Console.

A security layer and encryption are enabled.

Connects to monitoring services provided by Amazon, including Amazon CloudWatch and Amazon CloudTrail.

What is a Message Broker?

On-premises systems and cloud components are typically communicated using message brokers in a cloud environment. Asynchronous processing is used. The function of a message broker is to enable the transformation, routing, and validation of messages.

Messages are routed to the destination. Some features of Message Broker are mentioned below: 

  • Messages are translated between formal messaging protocols, allowing independent services to communicate directly.
  • Manipulate messages by decomposing them.
  • Data can be transferred using web services.
  • Messages that are delivered reliably.
  • The application responds to events and errors.
  • Support publishing and subscribing.

Benefits of Amazon MQ

You can rely on Amazon's messaging platform for reliability and ease of use:

  • Messaging APIs and protocols that conform to industry standards.
  • JMS, NMS, AMQP 1.0, STOMP, MQTT, and WebSockets are supported.
  • Administrates and maintains broker accounts.
  • Messages are stored across availability zones, ensuring message durability.
  • Highly available infrastructure.
  • Hardware deployment is not required.  

Difference between Amazon MQ and Amazon SQS and SNS.

Those who are aware of Amazon SQS and SNS may wonder when to use SQS or SNS and when to use MQ. Let's take a closer look at how they differ.

Amazon MQ

Amazon SQS and SNS

The Amazon MQ service is recommended if you want to move messages to the cloud quickly and easily or if you are currently using messaging in an existing application. Its APIs and protocols are industry-standard. The fully-managed nature and almost infinite scalability of SQS and SNS make them ideal for cloud-based applications.
Various broadcast protocols use the NMS, JMS, STOMP, MQTT, and WebSocket protocols. When there is a complex delivery rule, this can be useful. HTTPS protocols are supported.
Your payment is based on the amount of GBs that you use per hour. SNS and SQS are charged per request.
It supports publisher-subscriber and queueing. Amazon SQS cannot do pub/sub, but Amazon SNS can do it since it's a publisher-subscriber model.

How Amazon MQ works?

Basic Elements used in Amazon MQ are:

Broker

This is just a message broker environment that runs on Amazon MQ. It is the fundamental part of Amazon MQ, and it represents the broker instance class. There are two types of brokers:

Single-instance: There is only one broker. You can integrate your application with an Amazon EAS or Amazon EFS storage volume using this service.  

Active/Standby broker: Each broker is located in a different AZ and configured in a redundant pair to communicate synchronously with your application and Amazon Elastic File Storage.

Configurations

A configuration is an XML file containing all the settings for an MQ broker, and you can create a configuration for every broker before creating any brokers. Once your configuration is created, you can apply it to one or more brokers and keep track of your changes with configuration revisions.

Users and groups 

MQ brokers allow users access to queues and topics via the user interface. You can grant specific permissions to users. For example, some users can access the ActiveMQ web console.

Groups are merely semantic labels. You can assign groups to users and set permissions to let them send, receive and administer specific queues and topics.

Storage

Amazon MQ for ActiveMQ supports Amazon EFS and Amazon EBS and a broker storage mechanism that utilizes Amazon EFS for high durability and replication across multiple ages.

How Amazon MQ works for ActiveMQ and the Broker architecture?

Multiple brokers can work simultaneously, either a single instance or a standby broker. A single instance broker or an active-standby broker can be created with Amazon MQ for Active MQ. Active MQ can be accessed using any programming language that Active MQ supports and using common protocols and messaging APIs.

A variety of topologies can be configured for a network of brokers. Based on your application's requirements, such as high availability and scalability, a Concentrator hub and spokes, tree, or mesh may be used. It is possible to change the configuration revision and how it will be applied.

Network of Brokers

A network of brokers configured across AWS regions can be deployed in each region, with network connectors configured to their endpoints. The message forwarding is accomplished through the use of network connectors. Once the brokers are connected, these provide message forwarding. By setting up a network connection between broker one and broker two, messages are forwarded from broker one to broker two if a consumer exists on broker two for that queue or topic. Message messages are also sent from broker two to broker one if the network connection is configured as a duplex.

Using a broker network offers the following benefits: 

  • The throughput of aggregate data has increased.
  • Better Availability
  • Multiple Regions

Getting started with Amazon MQ

An Amazon Web Services account is required to access any AWS service. It is an Amazon account that is compatible with AWS services. To work with Amazon MQ, you need to have the AmazonMQFullAccess policy and the AWS credentials associated with your IAM user. There is a secret access key and an access key ID for the credentials.

 

You'll then need to navigate to Amazon MQ.

 

 

Create a Broker by clicking Get Started.

 

 

Depending on your needs, you can choose a single instance broker or an active instance broker. For this example, we will use a single instance with Amazon EBS. Click on the Next button.

 

 

After you enter the name and instance type for your broker, it is mentioned that it would take about 20 minutes to deploy.

 

 

As a final note, the status for a broker is "Creation in progress".

 

Amazon MQ Security

AWS places the highest priority on cloud security. AWS customers enjoy the convenience of choosing data centers and architectures that meet the most stringent security requirements.

AWS and you both have a responsibility for security. Security of the cloud and security in the cloud are described under the shared responsibility model as follows:

  • As a cloud provider, AWS is responsible for protecting the infrastructure that supports its services. In addition, it offers a secure service. Our compliance programs include regular testing and verification of our security by third parties. 
  • The AWS service you use determines your responsibility for protecting your data. As well as the sensitivity of your data and your company's requirements, you are responsible for complying with laws and regulations as well.

Logging and monitoring Amazon MQ brokers

The monitoring of AWS solutions is essential for maintaining their performance, reliability, and availability. Monitor all parts of your AWS solution to make it easier for you to identify a multi-point failure. You can monitor Amazon MQ resources and respond to potential incidents with the tools provided by Amazon.

Frequently Asked Questions

How can Amazon MQ be used?

Application Integration use cases are also suitable for Amazon MQ. You are developing new cloud-based applications using microservices, communicating with complex messaging patterns, and requiring low latency, high availability, and long-term resilience.

How do SNS and SQS differ?

An SNS sends messages to subscribers through a push mechanism and does not require subscribers to pull the messages. In a distributed application, SQS serves as a queue for messages through a polling model, which can be used to separate sending and receiving components.

How does RabbitMQ differ from ActiveMQ?

The ActiveMQ messaging protocol supports multiple instances and clustering environments and is used in enterprise projects to store messages. RabbitMQ is a low-level message broker that enables the communication between applications by executing the AMQP protocol.

What is ActiveMQ's port number?

ActiveMQ uses the following ports: 61616, 8181, and one random port.
