Hi,

I'm trying to use the Deployment Diagram to model server clusters. My difficulty is that the the server cluster is in active-passive mode and therefore, a grouping element is required.

In a simple 2 node-cluster, I would model 2 Node instances.
To denote the active-passive cluster, I would have to do either of the following:
1) draw a group/ boundary around the 2 node instances
2) use another (composite) node instance to contain the 2 node instances

Using the former poses issues as the group/ boundary element cannot be used to realize or depend on interfaces
The more correct way is to use the latter where the composite node will be able to realize or depend on interfaces. However node-in-node isn't supported in Astah

Anyone has any better suggestions? Or should this be a feature request?

Thanks!
