High network availability so that messages can be processed as quickly as possible and to reduce the likelihood of outages, which improves efficiency and keeps customers happy.

Message queue as a service (on a cloud server versus on your on-site network).

It also means the network won’t be slowed down by unnecessary requests.Īutomatic failover - There are multiple cloud systems so if one network fails, another can pick up the slack, avoiding delays. One-time delivery so there are no duplicate requests which might lead to confusion. you can set the program to start as soon as one message arrives on the queue, or once 10 messages have arrived on the queue, or once a certain number of messages above a particular priority have arrived. Message-driven processing - Apps can be triggered when a message arrives and stopped when a message has been processed.Įvent-driven processing - You can control the programs according to the state of the queue. Message priority - Programs can assign a priority to each message, determining its position in the queue. Push is also called “publish/subscribe” or “pub/sub” messaging.įirst in, first out (FIFO) - Messages are processed in the order in which they come in. Push and pull queues - The pull feature looks for new messages while the push feature notifies the user when a message is available. Real-time message processing so that requests get handled as soon as possible. Unlimited queues that can handle as many messages as necessary. A message gets sent to each program, requesting it to perform its function and then the results are sent back as messages. Small, self-contained programs can divide up the job instead of being performed entirely and sequentially by a single large program. Instead, one program puts a message on a queue and the other retrieves the message from the queue. The target application can retrieve a message whenever it starts up - it does not have to be running when a message is sent. Messages will remain in the queue until they are processed and then removed. The features of message queuing software include:Īsynchronous Messaging - Programs are time-independent, meaning they can make a request and then continue with other work while waiting for a response. This lends itself to flexibility and maximizes productivity. An IT department is often mobile and able to access the message on premises or with mobile tools.

The best message queue systems are extremely user-friendly, easy to scale ,and easy to maintain. A message queue makes it possible to keep processes in an application separate and independent. No interaction is required with the message queue by both participants at the same time. When the email is sent, the sender is able to process all other work without having to receive an immediate response from the receiver, decoupling the producer of the data to the consumer. The best example of asynchronous messaging is email. Some message queues are known as an asynchronous communications protocol (ACP), which, by definition, is waiting for response based on the receiver. Message queues are part of an everyday enterprise and do not always require an immediate response. Easy functionality is key for IT experts as there are usually priorities, so not having to immediately act on a message creates a bit of a buffer when managing many buckets at a time. The messages are then stored until the message is retrieved by the consumer.

The basic architecture begins with producers, which create these messages and then deliver them to the resulting message queue. The 'message' is transported between a producer (sending) and a consumer (receiver) application. These messages are usually small, things like requests, replies, error messages, or alerts about a finished task. Message queues allow for communication and coordination between various distributed applications, allowing different parts of a system to communicate with each other and to and process operations asynchronously.Ī message queue serves as a lightweight buffer that temporarily stores messages, and provides endpoints that allow software components to connect to a queue in order to send or receive messages.
