IBM.com - Understand Enterprise Service Bus scenarios and solutions in Service-Oriented Architecture. "This article identifies a set of minimum capabilities that fulfill the most basic needs for an Enterprise Service Bus (ESB) consistent with the principles of Service-Oriented Architecture (SOA). Identifying these minimum capabilities allows you to identify which existing technologies to use to implement an ESB to support an SOA. By considering how the requirements of a specific situation define the need for additional capabilities, you can then choose the most appropriate implementation technology for that situation."

Enterprise Service Bus (ESB) and Service Oriented Architecture (SOA)

SOA, or Service Oriented Architecture, is the buzz word today. SOA is an architectural style whose goal is to achieve loose coupling among interacting software agents. A service is a unit of work done by a service provider to achieve desired end results for a service consumer. Both provider and consumer are roles played by software agents on behalf of their owners.

An enterprise service bus (ESB) is a software infrastructure that enables service-oriented architecture (SOA) by acting as an intermediary layer of middleware through which a set of reusable business services are made widely available. An ESB helps enterprises obtain the value of SOA by increasing connectivity, adding flexibility that speeds change, and providing greater control over use of the important resources it binds.

About Enterprise Service Bus (ESB)

An Enterprise Service Bus is a standards based way to integrate systems to provide connectivity and interoperability across IT systems.

An enterprise service bus is an emerging standard for integrating enterprise applications in an implementation-independent fashion, at a coarse-grained service level (leveraging the principles of service-oriented architecture) via an event-driven and XML-basedą messaging engine (the bus). An enterprise service bus generally provides an abstraction layer on top of an Enterprise Messaging System which allows integration architects to exploit the value of messaging without writing code.

Today's IT organizations support hundreds of mission-critical business applications, often representing many generations of architecture and technology, and integration is a top priority for these organizations.

About Service Oriented Architecture (SOA)

Enterprise architects believe that SOAs help businesses respond more quickly and cost-effectively to the changing market conditions they may face.

Service-Oriented Architecture (SOA) expresses a software architectural concept that defines the use of services to support the requirements of software users. In a SOA environment, nodes on a networką make resources available to other participants in the network as independent services that the participants access in a standardized way. Most definitions of SOA identify the use of Web services (using SOAP and WSDL) in its implementation. However, one can implement SOA using any service-based technology.

Unlike traditional object-oriented architectures, SOAs comprise loosely joined, highly interoperable application services. Because these services interoperate over different development technologies (such as Java and .NET), the software components become very reusable.

SOA provides a methodology and framework for documenting enterprise capabilities and can support integration and consolidation activities.
