What are the different messaging systems?

There are two types of messaging patterns. The first one is a point-to-point and the other one is “publish–subscribe” (pub-sub) messaging system. Most of the messaging systems follow the pub-sub pattern.

How do messaging systems work?

The messaging uses a “store and forward” approach to transmitting messages. The data is packaged as messages, which are atomic, independent units. When the sender sends a message, the messaging system stores the message and then delivers it by forwarding the message to the receiver’s computer.

What is message-based integration?

Message-based Integration is one of the common categories of patterns for connectivity solutions. An Enterprise Service Bus can extend an existing messaging infrastructure by providing an environment for building and deploying message-based applications at the infrastructure level.

What is message-based API?

Messaging API refers to any service that enables developers to implement various messaging technologies in an application via a single programmable interface.

Which is a characteristic of a message base system?

A characteristic of message base systems like Azure Service Bus is the contract that exists between producer and consumer. Both sides know exactly how the message looks like, the data format and expect information in a specific way. In general, even the producer expect a response in a specific format.

How does a message based communication system work?

A client makes a command or a request to a service by sending it a message. If the service needs to reply, it sends a different message back to the client. Since it’s a message-based communication, the client assumes that the reply won’t be received immediately, and that there might be no response at all.

What is a message-based middleware ( MOM ) system?

The message-based model, coupled with the mediation of the provider, makes it possible to create a system of loosely coupled components. MOM comprises a category of inter- application communication software that generally relies on asynchronous message-passing, as opposed to a request-response architecture.

What makes an asynchronous message a message based communication?

Since it’s a message-based communication, the client assumes that the reply won’t be received immediately, and that there might be no response at all. A message is composed by a header (metadata such as identification or security information) and a body. Messages are usually sent through asynchronous protocols like AMQP.
