- 13. What is TOSCA? •Goal:cross cloud, cross tools orchestration of applications on the Cloud •Status: –Version 1 approved (XML ) –Version 2 (YAML!) in design
- 14. Why TOSCA? •Standard •Can Describe –AnyTopology –Any Automation Process •Portable between Clouds and Tools

- 16. What’s in aTOSCA Topology? •component in the topology are called Nodes •Each Node has a Type (e.g. Host, BD, Web server). –The Type is abstract and hence portable –The Type defines Properties and Interfaces •An Interface is a set of hooks (named Operations) •Nodes are connected to one another using Relationships

- 25. Workflows TOSCA 1.0– Workflows (Plans) are in any WF language. Strong preference for BPMN 2.0 TOSCA 2.0 – No change Cloudify 3.0 take – Workflows are also tool specific, currently we use Radial (Ruby based DSL) but seeking an alternative for future versions
