2014 March:TOSCA Simple Profile in YAML Version 1.0 Working Draft 01 is approved by TC and demonstrating significant progress for this new language rendering. The final version will align with TOSCA v1.1, currently in development.

2013 November: The Topology and Orchestration Specification for Cloud Applications (TOSCA) Version 1.0 is now an OASIS Standard with 70 members voting to approve it. See the press announcement.


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. 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

For more information, see the TC Charter.
