2015 January:TOSCA Simple Profile in YAML Version 1.0 Committee Specification Draft 02 has been published by the TC. Progress continues on this new language rendering. The final version will align with TOSCA v1.1, currently in development.
See new TOSCA video playlist on YouTube.
The TOSCA TC continues to make excellent progress developing the next major iteration of the TOSCA specification, which is expected to be available as a Candidate OASIS Standard during the first half of calendar 2015. Starting in 2014, responding to feedback from the open source community and other implementers, the TOSCA TC started work on the next release of TOSCA with the TOSCA Simple Profile for YAML. The TOSCA TC has also formed dedicated workgroups in support of significant use cases, which are highlighted below.
Infrastructure and Software Components
The TOSCA TC has made a number of significant interoperability improvements such as built-in definitions for commonly found infrastructure (e.g., Compute, Storage, Network, etc.) and software components (e.g., Web Servers, Databases, etc.) along with a small set of simple relationships that connect them together. Many other functional enhancements and interoperability improvements have also been included, while additional efforts on overall model simplification have also been quite successful.
Users of container technologies, such as Docker and Rocket, as well as container management technologies such as Kubernetes, Mesos, and LXD, and many other varieties of container technologies, will also find that TOSCA has evolved to further enhance the value and flexibility across all these technologies in a completely agnostic fashion.
Monitoring and Metrics
In 2015, the TOSCA TC is extending the specification to support declarative modeling for storage and network definition capabilities. Additionally, the TOSCA TC is now taking a similar approach to define application-centric monitoring in the specification. This will enable TOSCA implementations to provide holistic views of health, availability and performance for cloud applications across all the software components in a deployment topology independent of the underlying monitoring technologies. It will also enable application component vendors and architects to specify metrics for collection.
As a result, TOSCA will make monitoring portable and provide customers choice in fulfilling their monitoring needs in a combination of ways including the use of cloud platform monitoring features, 3rd party monitoring services, or custom monitoring using monitoring components also defined as part of TOSCA topologies.
NFV - Network Function Virtualization
In the longer term, there is growing interest in NFV (Network Functions Virtualization) within the TOSCA TC, which has a number of members who are also active in the ETSI NFV Industry Work Group and other related activities. The TOSCA TC recently formed a workgroup focused on creating a "TOSCA Simple Profile for NFV."
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

November 2013: Topology and Orchestration Specification for Cloud Applications (TOSCA) Version 1.0 is now an OASIS Standard. The Standard is available in PDF (authoritative), HTML, and editable source formats. The complete specification including the schema can also be downloaded in this ZIP file
2013 February: A non-normative Primer for TOSCA Version 1.0 is now available.
The following subcommittee is active.
TC liaison to ISO/IEC JTC 1 SC38 WG3 - Mike Edwards
TC liaison to ETSI NFV - Deepanshu Gautam and Chin Qinjin
Although not produced by the OASIS TOSCA TC, the Open DataCenter Alliance also conducted a proof-of-concept based on TOSCA v1.0 that may also be of interest. See the press release of January 8, 2014 with links for more information.
