Subject: [OASIS Issue Tracker] (TOSCA-265) Different flavours of the same Service
Luca Gioppo created TOSCA-265: --------------------------------- Summary: Different flavours of the same Service Key: TOSCA-265 URL: https://issues.oasis-open.org/browse/TOSCA-265 Project: OASIS Topology and Orchestration Specification for Cloud Applications (TOSCA) TC Issue Type: Improvement Components: Spec Reporter: Luca Gioppo The use case is: 1) I have different "flavours" of the same service that is for example a "transparency portal" composed by Postgresql node +tomcat-lifaray node + apache reverse proxy node as a basic topology for a minimal PA, but I could want to change the topology to scale the service for a bigger PA and I cloud have a cluster of tomcat and a couple of Apache in front with a load balancer. As can be seen these are two different topology that cannot be "just scaled" but need different planned topology. Logically this is 1 service thus 1 TOSCA file but I have different sizing. In the XML spec we have that Definition allows for having more than 1 ServiceTemplate and this is logical since the ServiceTemplate contains all the needed elements to allow for different sizing. Is a proper interpretation of the standard or am I stretching it too far? I believe that this use case allows the orchestrator to interpret the TOSCA file properly looking at how many ServiceTemplate are there and presenting the end user with a choice of sizing for the service and afterwards the request for the inputs -- This message was sent by Atlassian JIRA (v6.2.2#6258)
