From the OASIS Web Site: TOSCA will enable the interoperable description of application and infrastructure cloud services, the relationships between parts of the service, and the operational behavior of these services (e.g., deploy, patch, shutdown)–independent of the supplier creating the service, and any particular cloud provider or hosting technology. TOSCA will also make it possible for higher-level operational behavior to be associated with cloud infrastructure management.

By increasing service and application portability in a vendor-neutral ecosystem, TOSCA will enable:

• Portable deployment to any compliant cloud
• Smoother migration of existing applications to the cloud
• Flexible bursting (consumer choice)
• Dynamic, multi-cloud provider applications
