TOSCA and OpenTOSCA: TOSCA Introduction and OpenTOSCA Ecosystem Overview
20 likes49,811 views
The document provides an overview of the OASIS TOSCA (Topology and Orchestration Specification for Cloud Applications) and the OpenTOSCA ecosystem, focusing on the goals of automation, portability, interoperability, and a vendor-neutral environment. It details the components of cloud application deployments using TOSCA, including management operations, deployment plans, and the structure of a Cloud Service Archive (CSAR). Additionally, it highlights the CloudCycle modeling tool and its functions within the OpenTOSCA framework.

- 21. Portability Note CloudCycle TOSCA deals with portability of Service Templates Portability of the ingredients of an IT Service (especially the code artifacts) is not addressed by TOSCA Similarly, mobility of data used by a corresponding service instance is not in the scope of TOSCA © Binz, Breitenbücher, Kopp, Leymann | IAAS | University of Stuttgart 21
- 22. Why is this portable ? CloudCycle Management operations defined in TOSCA standard Management Operations, i.e., Implementation Artifacts, are deployed by the TOSCA runtime Plans defined using standards (e.g., BPEL, BPMN) Plans (1) and Management Operations (2) are “bound” (i.e., connected) by the container Implementation Artifacts on the realization level © Binz, Breitenbücher, Kopp, Leymann | IAAS | University of Stuttgart 22
