Andrea Turli commented on JCLOUDS-1308:
---------------------------------------

Interesting point [~graemem], I think we should close this bug.
Can you please open another jira issue (improvement or wish, would be appropriate, I think)
where you can explain better what you are trying to achieve? Thanks!

> For Azure ARM, the default behaviour when creating a VM has changed with regards to VNETs/Subnets.
> Previously, if no networking configuration was provided JClouds would create a default
VNET per region. The implementation of this can be found [here|https://github.com/jclouds/jclouds-labs/blob/4f50e7d65a6d7e1a3d06efcf557b363e55118238/azurecompute-arm/src/main/java/org/jclouds/azurecompute/arm/compute/strategy/CreateResourceGroupThenCreateNodes.java#L147].
This was useful as it meant that a user could rely on VMs being able to access one another
on their subnet IP addresses, even when a network was not provided (I believe this is the
same as other clouds, but I am not too familiar with JClouds).
> Now, when no networking configuration is provided we create a VNET per group id. For
our usage, this is a bit of a problem as it means by default each VM is getting it’s own
network.
> To see a history of these changes please see the commit [here|https://github.com/jclouds/jclouds-labs/commit/54e5ce50a43250c4f87414506b3bba4d8365284e]
that moved to having a VNET per resource group and then [here|https://github.com/jclouds/jclouds-labs/commit/dbadb279f14848f21879f7eb6c7136e1a5f11192],
that moved to using just the groupID.
> I propose we go back to the old way, where we have a default resource group, VNET and
subnet per region. This will mean that by default, VMs will be able to speak to each other
on there private IPs. If that is not possible, could we have a template option that will allow
us to turn this behaviour on? 
> I am very happy to work on the solution myself, but would like direction form the community
before investing too much time.
