Agenda for Tuesday 11/10/2020 TOSCA Language Ad-Hoc meeting

[Chris Lauwers <lauwers@ubicity.com>]

We will continue the discussion from last week about Instance Model using the following as context:

 

• Based on a suggestion by Peter Bruun, I presented an overall “TOSCA Architecture” in the following document: https://www.oasis-open.org/apps/org/workgroup/tosca/download.php/67934
• Peter observed that the architecture I proposed assumes a catalog/inventory-based orchestrator. Many implementations may not be catalog based. Peter proposed a “minimal” architecture alternative in the following: https://www.oasis-open.org/apps/org/workgroup/tosca/download.php/67935
• Based on Peter’s observation, I created a slightly reworked version of the “minimal” architecture in the following: https://www.oasis-open.org/apps/org/workgroup/tosca/download.php/67958
• Assuming we agree that a “minimal” TOSCA architecture includes an “instantiation” step, then we can discuss the issues related to “instantiation”, many of which related to “cardinality”, not just of nodes but also of relationships. Tal has previously highlighted some of these issues in the following: https://www.oasis-open.org/apps/org/workgroup/tosca/download.php/66087 (although Tal mentioned he may have an updated version).

 

Looking forward to another very stimulating discussion.

 

Thanks,

 

Chris
