In today’s technology powered world, organizations strive to provide customers with topnotch business solutions. There is a stiff competition between businesses for providing effective and efficient solutions that meets the customer demands.
Most enterprises are driven by application and databases that collect tons of information and these applications may be built of different technologies residing in different servers. Service Oriented Architecture (SOA) allows access to specific functions and services regardless of functionality, location and information. Enterprise Architecture Integration (EAI) provided integration of various systems and applications for carrying out day to day businesses by integrating in central hubs called brokers. These EAI models were heavy weight, expensive and not reliable. As a result of which the new EAI model Enterprise Service Bus (ESB) emerged. Let’s go through this new architectural model in detail.
ESB also referred as Message Broker is an open-standards based software architecture model that can be used for deploying communication between mutually interacting applications in a Service Oriented Architecture (SOA). This middleware solution which allows interoperability among heterogeneous environments has the ability to virtualize services. With ESB service container, service virtualization, insulation of protocols, QoS requirements and infrastructure aspects are all achievable. ESB allows developers to build a service that is independent from the technology that expose capabilities.
The core concept of ESB architecture is to leverage a communication bus to integrate different applications and enable each application to communicate with the bus. This decouples systems from each other and allows communication between systems on the bus without dependency.
Here we list the major functionalities supported by ESB:
1. Application Operability
With ESB, a common protocol can be utilized for connecting multiple applications irrespective of the language or platform in which the application is developed.
ESB supports application specific or language specific security features.
3. Plug n Play
ESB allows easy connection or integration of new applications without hurdles.
4. Message Routing
ESB takes care of all message transfers comprising of producer and consumer without worrying about the required data structure.
Application running on ESB architecture allows easy maintenance of applications as one application doesn’t interfere with the other. This allows easy upgrades for the application.
So why do you need ESB? Ask these questions before proceeding to an ESB solution:
- Do you need to integrate more than 3 applications/services?
- Do you require more than one type of communication protocol?
- Does your business have requirements to plugin more applications in the future?
- Do you require to control your applications at one place?
- Do you need to use shared memory across applications?
- Do you want to leverage message routing capabilities?
Go for an ESB solution that can satisfy your business needs. Here are some of the popular open source ESB solutions:
- JBoss ESB
- Apache Service Mix
- Mule ESB
