30-day Public Review for Topology and Orchestration Specification for Cloud Applications V1.0
The OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC  members have recently approved a Committee Specification Draft (CSD) and submitted this specification for 30-day public review:
Topology and Orchestration Specification for Cloud Applications Version 1.0
Committee Specification Draft 06 / Public Review Draft 01
29 November 2012
The concept of a "service template" is used to specify the "topology" (or structure) and "orchestration" (or invocation of management behavior) of IT services (or simply "services" from here on). Typically, services are provisioned in an IT infrastructure and their management behavior needs to be orchestrated in accordance with constraints or policies from there on, for example in order to achieve service level objectives. This specification introduces the formal description of Service Templates, including their structure, properties, and behavior.
The OASIS TOSCA TC works to enhance the portability of cloud applications and services. 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.
The TC is currently focused on the creation of a non-normative Primer that illustrates suggested use and provides examples based on the TOSCA language. It has also launched an Interoperability Subcommittee.
Public Review Period:
The public review starts 14 December 2012 and ends 13 January 2013.
This is an open invitation to comment. OASIS solicits feedback from potential users, developers and others, whether OASIS members or not, for the sake of improving the interoperability and quality of its technical work.
