TOSCA and Eclipse Winery Fundamentals
Describe TOSCA modeling fundamentals and how Winery visualizes them, to provide a basis for understanding the new functionality described below.
The basic elements of a TOSCA design are illustrated in the diagram below, taken from the TOSCA 1.0 specification. A service template contains all the type definitions required by the design plus a topology template. The topology template consists of a set of nodes (or node templates) and relationships (or relationship templates) between those nodes. The topology template represents the structure of the service as it will be deployed. The nodes are abstract functional blocks, representing such things as software applications, libraries, virtual machines (or other "compute" nodes), and so on. Relationships describe dependencies between nodes, which can encompass network connections and APIs, and also such things as which host runs a given piece of software.
