> Currently each node template can only have a single node.
> We need to support having multiple nodes of a given node-template at service creation
time. The mechanism for this should take into consideration future stories which would require
allowing scaling the number of nodes of a node-template up or down.
> Note: the term {{default_instances}} appears in several places in the code ([1|],
- we could perhaps use this or an extension based on this idea to support this issue.
> One other thing that should be taken into consideration (but perhaps be moved to a separate
JIRA issue) is the implicit declaration of multiple instances via the capabilities&requirements
mechanism in TOSCA - We need to decide if to support this as well or not, and if we do, how
does this play together with the primary method of declaring multiple nodes (or perhaps would
this be the only method of doing so?)
