-- Information about the Candidate OASIS Standard and the TOSCA TC --

Cloud computing offers a cost-effective way for businesses to host their applications and services in scalable environments while reducing their need to maintain their own large datacenters. It is even more valuable if applications and services can be ported to alternative cloud environments while keeping services interoperable.

The TOSCA specification provides a language to describe service components and their relationships using a service topology, and it provides for describing the management procedures that create or modify services using orchestration processes. The combination of topology and orchestration in a Service Template describes what is needed to be preserved across deployments in different environments to enable interoperable deployment of cloud services and their management throughout the complete lifecycle (e.g. scaling, patching, monitoring, etc.) when the applications are ported over alternative cloud environments.

More information on TOSCA can be found at TC's website. In addition, the TC has published a primer that gives a quick introduction to the specification [2].
