Clean up messy data flows
Consolidate disparate middleware
products into a few strategic
choices
Improve documentation
Provide flexibility for future
application changes
Conform to emerging IT standards

Client Issues
1. When and why will enterprise service
buses (ESBs) become relevant
to mainstream businesses?
2. How will companies address the three
core problems of application integration:
data consistency, multistep processes
and composite applications?
3. Which technologies and providers will
dominate the Enterprise Nervous System
(ENS) during 2005 through 2010?

"Providers"
Use point-to-point connections on plain Web services for:

Small applications of fewer than 20 services or event types

Standard service levels

Moderate throughput and latency requirements

All clients and services using Web services technology
from the same one or two middleware providers

Stable business requirements, relatively slow rate of change
Using ESB Infrastructure

"Providers"
Use ESBs or similar ENS infrastructure for:

Large applications of more than 20 services or event types

Demanding service levels including reliable delivery, logging, auditing,
publish-and-subscribe, SLA monitoring, high security

High-throughput and low-latency requirements, non-HTTP traffic

Some clients and services using non-Web-services interfaces
or Web services technology from two or more middleware providers

Frequent changes in business requirements, new services added,
services modified, new service providers inserted

Recommendations
 To meet the escalating requirements of modern
business, every company must have:
 An application integration strategy
 An integration competency center
 A comprehensive ENS middleware infrastructure
 Use business component architecture in all
major new applications.
 Prepare for event-driven applications:
the "next big thing."
 Add an ESB to your IT strategic plan
and application architecture.
