Enterprise Computing History (Blank Page) © 2004 IBM Corporation
1st Generation Enterprise Computing • Discrete Business Applications within Enterprise • Coupled by manual or batch processing • Separate application sets like Order, Inventory, Accounting • Through print-out or screen-scraper • Local optimization on each business operation • Data silo issue © 2004 IBM Corporation
2nd Generation Enterprise Computing • Monolithic Integration with Package Apps around Business Process • ERP package integrates a set of application tightly but monolithic • Data silo issue resolved within ERP • Needs many customization to adopt • New business application packages create higher level data silo issue • Between application packages like CRM, e-commerce, SCM etc. • B2B and B2C create new integration needs across enterprises © 2004 IBM Corporation
3rd Generation Enterprise Computing • EAI needs by On-demand Business • ERP and monolithic application packages integration through EAI (Enterprise Application Integration) • Has to be responsive through entire processes as enterprise in network economy • Still tightly non-flexible integration between business processes • No dynamic partnership enabled • Difficult to change and create new process (70% of IT budget spent for current system-associated maintenance) • Difficult to change IT resource for business transaction fluctuation • Huge spike as e-commerce nature © 2004 IBM Corporation
Next-Generation Enterprise Computing • Enterprise Application Needs for Network Economy • Build business process dynamically as composite services within Enterprise and across Enterprise • Disintegrate monolithic business processes • Long business transaction to complete a business process • Dynamic resource allocation for transaction fluctuation © 2004 IBM Corporation
