OASIS TOSCA

On 16 January 2014, OASIS TOSCA Technical Committee approved TOSCA 1.0 as a standard. Version 1.3 was approved on 26 February 2020 and version 2.0 was published as a full OASIS standard on 9 September 2025. ==Specification==

The specification is fully described in the standard and has been cited in academic papers such as The standard is maintained by the OASIS Technical Committee in a github repository and there is a companion repository for community contributions. Related specifications 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. Amazon AWS CloudFormation template The AWS CloudFormation template is a JSON data standard to allow cloud application administrators to define a collection of related AWS resources. CloudFormation is a proprietary format from AWS, that is not TOSCA based, and therefore does not bring the promise OASIS TOSCA is targeting. Check this grammar compared to the OASIS TOSCA one . OpenStack Heat The OpenStack Foundation has also defined a similar standard for specifying resources and the orchestrations for managing infrastructure, and application lifecycles. The heat-translator project was one of the first to adopt TOSCA for standardized templating. == Related projects==
