OpenTOSCA - Open Source TOSCA Ecosystem

OpenTOSCA Ecosystem Overview

OpenTOSCA provides an open source ecosystem for the OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) standard which was developed at the University of Stuttgart. As the name indicates, TOSCA has two parts (i) the topology, describing the components and relations of the application, and (ii) the orchestration, explicitly modelling management aspects of the application.

The OpenTOSCA ecosystem consists out of three parts, as shown in the figure above:
  1. OpenTOSCA Container, a TOSCA runtime environment
  2. Winery, a graphical modelling TOSCA tool
  3. Vinothek, a self-service portal for the applications available in the container
