Abstract
AbstractIn part I of this paper, we described the origins and evolution of Software as a Service (SaaS) and its value proposition to Corporate IT, Service Providers, Independent Software Vendors and End Users. SaaS is a model in which software applications are deployed, managed, updated and supported on demand—like a utility—and are served to users centrally using servers that are internal or external to the enterprise. Applications are no longer installed locally on a user's desktop PC; instead, upgrades, licensing and version control, metering, support and provisioning are all managed at the server level. In part we examine the lessons learned in researching, building and running an SaaS service. Copyright © 2002 John Wiley & Sons, Ltd.
