Oracle will allow customers to convert money they're now spending on annual support for on-premises into software subscriptions for its SaaS (software as a service) applications, in a bid to block defections to competitors such as Workday and Salesforce.com. Dubbed Customer 2 Cloud, the program lets Oracle customers using its on-premises HCM (human capital management) and CRM (customer relationship management) software switch over to cloud versions. E-Business Suite, Siebel, PeopleSoft and JD Edwards EnterpriseOne customers are eligible.
