OASIS TOSCA
Topology and Orchestration Specification for Cloud Applications (TOSCA), is an OASIS standard language to describe a topology of cloud based web services, their components, relationships, and the processes that manage them. The TOSCA standard includes specifications to describe processes that create or modify web services.
History
On 16 January 2014, OASIS TOSCA Technical Committee approved TOSCA 1.0 as a standard.

Commercialization of cloud computing offerings has required manageability of tenant applications, particularly on a large scale. As such, vendors who offer their services to a wide market have written related standards that predate, or have been developed concurrently, with the OASIS TOSCA standard.
