A default network is now created when deploying to Azure ARM
In an upcoming release of JClouds, support for Azure ARM will be added. The
JClouds code for Azure ARM will place each created VM into a network based on
it's group ID. As we do not use the concept of a group ID in Brooklyn, this
means that each VM deployed by Brooklyn is deployed in it's own subnet.
For most other clouds, a sensible default network is provided by the cloud.
As such a Brooklyn user can be assured that if he deploys a blueprint with
multiple VMs, they can reach each other on the private IPs that are provided.
Unless we create a default network in Azure, those blueprints will not be
portable and a user will have to manually create a network first. I believe
that it is confusing for a user to have the clouds act differently on
networking, which is an essential part of Brooklyn.
A few things to mention:
*) The default network/subnet is only created when needed
*) The default network/subnet is created per region
*) It is never cleaned up or deleted
--------------------------------------------------------------------
As a side note, I discovered this as AMP, which is a downstream project of
Brooklyn, pulled in and was using Azure ARM support from JClouds. An older
version of the JClouds code created the default network, but was recently
removed meaning a regression in AMP. The code which I have added to create a
default network is based on the JClouds code.
