IBM Emptoris Strategic Supply Management Managed Cloud Delivery is an optional IBM hosting service for organizations that prefer purchasing perpetual software licenses over license rental via Software as a Service (SaaS).
SaaS is both a commercial and delivery software model whereby clients subscribe to services for a term with applications centrally delivered via a cloud computing environment and accessed by users over the Internet. Increasingly businesses are using SaaS as a common commercial and delivery model because of its ability to help reduce costs and simplify deployment.
The Managed Cloud Delivery provides flexibility for customers who wish to own the software license but pay an additional, variable charge for the hosting service. The Managed Cloud Delivery provides the same benefits of the SaaS delivery model - fast deployment, limited upfront costs and reduced impact on internal IT resource.
