Message Queue (MQ) software enables asynchronous communication between applications within serverless and microservices architectures. This means that they enable applications to seamlessly process requests, manage workloads, and handle complex workflows, without a developer having to couple or integrate them. To achieve this, the MQ software receives messages from the sending application called a producer, and adds those messages to a queue, where they wait to be processed by a receiving application. These receiving applications, also called consumers, process the messages in the queue and perform necessary actions based on the content of the message.
By storing and routing messages in this way, MQ software ensures that messages are delivered accurately and efficiently. It also helps to simplify the application architecture, streamline development, and enable greater flexibility for future expansion.

In a modern software architecture, applications are often run across multiple different locations and servers. In this type of distributed environment, these applications need a way to communicate with one another. Message queue software can help them do that.
A message queue is a software component that allows applications within serverless and microservices architectures to communicate asynchronously (i.e., without real-time back-and-forth), without having to directly couple or integrate the applications. As the name suggests, message queue software stores messages (i.e., data packets that applications create to send information to other applications) in a queue, then delivers them to the recipient when that recipient is ready to receive the message. This enables the sender to keep operating and move onto the next task, while the recipient processes the message in its own time. It also means that, in the event there’s something wrong with the network or receiving application, the message isn’t lost; it’s simply stored safely in the queue until it can be received.
The messages added to a message queue are usually small and specific—such as error messages, requests, replies, or information needed for tracing or logging—and they don’t need an instant reply.
A message queue is made up of three parts: a message broker, a producer client, and a consumer client. The producer is a client application that creates a message. The message broker receives the message from the producer and stores it in the queue. The consumer is another application that connects to the queue and retrieves the message when it’s ready to process it.
Now you know the different components of MQ software, let’s take a look at the modes they can work in.
There are two different message queue modes: Point-to-Point (PTP) and Publish-Subscribe (Pub-Sub).
In the Point-to-Point mode, the message is sent from the producer to a single consumer. The producer needs to know which queue the consumer is on, and possibly also the queue manager name, before being able to send the message. This type of message queue is common within environments that handle lots of repetitive transactions, such as a controller in a factory communicating with a piece of machinery.
In the Publish-Subscribe mode, multiple consumers can receive a message from a single producer. The producer creates messages on a specific topic, and all consumers (more commonly referred to as “subscribers” in this mode) that have subscribed to that topic can retrieve the messages from the queue—usually without having to send a response. In this mode, the producer doesn’t need to know specific details about the application that’s going to be consuming the message. This means the producer and the consumer can be decoupled.
There are a few reasons that you might consider implementing message queue software:
