The Problem: Disparate Interfaces Costs Business Money
“About 35 percent of an enterprise’s software budget is spent on maintaining the multitude of point-to-point application links already in place.”
— Gartner Group, 04/2003
“Maintaining and managing point-to-point links was costing them an average of 29% of their IT budgets.”
— CIO Insight, 02/2003
“The three most common inhibitors to achieving a strong ROI on EAI initiatives are:
1. Not having a shared-services model 2. Not having application-neutral interfaces 3. Not fostering a culture of reuse within ones development teams. — Meta Group, 06/2003

“A lightweight connectivity infrastructure built using JMS, XML, and Web Services standards.”

The problem with this view
The “Web Services-only” world does not yet exist. In the short term, they -- in fact -- make the situation more complex.

The Enterprise Service Bus – What is Needed?
A communications “architecture” that enables software applications that run • on different platforms and devices • or which are written in different programming languages • or which use different programming models • or which use different data representations to communicate with no disruption to existing applications or interfaces.

Standard Life was an early adopter of the ESB pattern
“We needed to maintain independence of underlying infrastructure, allowing us to change the infrastructure without rewriting the applications.” The key elements of the new architecture were determined to be an intelligent messaging hub linking application services, XML as the common language of integration messages, and Java as the platform for new application services running on a variety of operating systems. While it was radical at the time, today we recognize Standard Life’s new architecture as an early example of the ESB integration pattern. “We are definitely seeing improved speed to market – directly attributable to the new architecture and the way we are designing the applications.”

Summary
The objective of an ESB is to reduce the cost of managing disparate interfaces:
A communications “architecture” that enables software applications that run on different platforms and devices or which are written in different programming languages or which use different programming models or which use different data representations to communicate with no disruption to existing applications or interfaces.
Web Services are the way forward…. BUT the standards are still evolving and they don’t help you integrate the other 98% of your applications. IBM has the most comprehensive ESB offering available today that accommodates the move to Web Services AND everything else …and it is built on PROVEN technology!
