What is Azure Service Bus?

Azure Service Bus

Azure Service Bus is a form of messaging system. Its main function is to offer interaction between applications and services. It is a multi-tenant cloud messaging service, multiple users share the services. The application developer, who creates a namespace, then defines the communication mechanisms needed within that namespace.

Microsoft Azure Service Bus is a trustworthy information delivery service. The main agenda is to help make communication easier. When several parties want to switch information, they want a communication facilitator.

Service bus could be implemented by three communication mechanisms:

  • Queues
  • Topics
  • Relays

 

  • Queues

It offers first in first out (FIFO) delivery mechanism to a number of recipients. Messages delivered through queues are asynchronous and decoupled.

  • Topics

It provides one-directional communication using subscription. It offers filter for messages based on the filter applied onto that.

  • Relays

It provide bidirectional medium of interaction, it generally does not store message like Topics and Queues. It sends the message to the recipients.

Service bus centers on increasing the product range of communication between application and devices connected all over the internet. It uses queues, topics, and relays mechanisms through cloud-based technology for communications

It’s found in Social messaging services (Facebook, Gmail, YouTube etc.) and Ticket allocation system (Air tickets, concert tickets, etc). It’s used to broadcast usually the one message to multiple associated users.

With increasing competition in the global market, top software testing companies and development companies are choosing this technology. Features of it are to get in touch a credit card application running over a cloud platform (Azure) to a credit card application over phones. It does not require to improve the whole code of something but just change the WCF transport extension and configuration. Customization and extending WCF architecture is simple because one can add/replace modules quickly in it.
