Application Integration in Intranets and
Extranets

• Antti Kiviluoto 16.3.2004

Heterogeneous infrastructure

• Today, companies have distributed their
  business-critical applications to several
  different systems everything cannot be done
  within one system (e.g.ERP)
• Critical business processes require communication
  between these systems and information sharing
  will increase in future
• These systems are not necessarily located inside
  the company, but business processes may require
  communication between companies

EAI and B2Bi

• EAI Enterprise Application Integration
• B2Bi Business-to-Business Integration
• Two different acronyms, same needs
• To speed up and automate business processes
• To reduce costs and improve service
• Differ from each other e.g. by
• Security needs (encryption, authentication)
• Used protocols (in-house, EDI, RosettaNet, ebXML
  etc.)

Two ways to integrate
Point-to-point integration
Centralized integration

• It is relatively easy to make two applications
  communicate with each other just link them with
  appropriate interfaces and conversions
• What if there are more than two applications?

Two ways to integrate
Point-to-point integration
Centralized integration

• Making more than two systems communicate with
  each other using point-to-point links will result
  in spaghetti integration

• Maintenance of integration is a
  nightmare change in one system
  reflects all over the architecture
• What if these applications are located in
  different companies?

Two ways to integrate
Point-to-point integration
Centralized integration

• Using a centralized integration hub easies
  maintenance dramatically and reduces the total
  cost of ownership
• If one of the system changes, there is one link
  that requires re-configuration easier change
  management

Integration Market and Products

• Product license revenue 1,37 billion USD (23 of
  the middleware segment) Gartner
• Consolidation going on among integration vendors
• IBM nro. 1 in the integration broker market,
  market share 19,1
• Other strong vendors Microsoft, BEA and
  WebMethods
