Rollbase in Gartner's What You Need to Know About Cloud Computing report:
The Web platform service market is multilayered and complex. Hosting-oriented offerings (from IBM, Dell, Rackspace, OpSource and others) will compete with new utility offerings from Amazon.com, MediaMax and others. The applications from Workday, NetSuite, RightNow and salesforce.com run over their own platforms, but many smaller and newer application ISVs build on the growing availability of development and runtime environments for the cloud, including Force.com, Rollbase, LongJump, Bungee Connect and others. In time, this variety of offerings will likely consolidate, but not in the immediate future, where we expect a continuing emergence of new innovative players and offerings.
