Enterprise Service Bus: Some Interesting Facts

by Attune World Wide / /

An Enterprise Service Bus (ESB) is software architecture for middleware that can help your organization to develop and maintain an effective enterprise IT architecture. An ESB helps you continuously lower down the IT cost to the business, respond hastily to the new business requirements, be flexible and agile, and seamlessly integrate applications, existing and new customers and business partners as well as cloud services. Basically, an ESB  is a system with which all the services of an organization are connected and it helps in accessing all the services with ease.

Some of the most interesting facts pertaining to Enterprise Service Bus subsume:

  • Open Source ESB like Mule ESB completely takes away the pain involved in integration by delivering everything which is needed for connecting the enterprise to cloud and on-premises systems on an open and single platform.
  • One of the most sought after features of ESB is that it acts as a single point of access. Thus, the biggest advantage of connecting all the services and clients through an enterprise service bus is that clients need only to look for services at a single location which is the ESB itself. If a service is moved from a server to be run by another server, all you need to do is to reconfigure the ESB and the clients will still access the service by ESB. This implies that change in location will not affect the functioning of the service.
  • Another interesting fact about ESB is that it can act as transaction manager by coordinating distributed in which multiple services participate. Instead of forcing the client to manage these transactions, ESB does it by itself.
  • ESB can also act as the Security Manager by implementing the security aspects including authorization and authentication. Even if an application’s service does not have any authorization and authentication, the ESB can need these in the service interface which is exposed to the client.
  • An Enterprise Service Bus solution can act as the gateway to the world. If some clients need access and connection to the services which are running in the outside world, they can use ESB which can potentially function as a gateway for these services.
  • An ESB can easily and quickly distribute information across an enterprise whilst masking any differences among the software architectures, network protocols and the underlying platforms.
  • An ESB has the capability to provide incremental enterprise solution implementations so that all the enterprise applications and services do not need to be changed all at once or immediately.
  • As per IBM ESB cannot be regarded as a new software product, rather it is a new way of looking at how applications can be integrated, information can be manipulated and resources can be coordinated.
