             Summary: Azure: suspending a node also deallocates it
                 Key: JCLOUDS-1139
                 URL: https://issues.apache.org/jira/browse/JCLOUDS-1139
             Project: jclouds
          Issue Type: Bug
          Components: jclouds-labs
    Affects Versions: 1.9.2
            Reporter: Ladislav Thon


(Note that this is about the "classic" {{azurecompute}} provider, _not_ about {{azurecompute-arm}}.)

The {{AzureComputeServiceAdapter.suspend}} calls the {{VirtualMachineApi.shutdown}} method with a parameter of {{StoppedDeallocated}}. Per https://msdn.microsoft.com/en-us/library/jj157195, this parameter makes Azure release all the resources used by the VM. This causes the suspend operation to take a lot of time and any other following resume will also take a lot of time.

I think there should be an option that would cause {{AzureComputeServiceAdapter.suspend}} to call the {{VirtualMachineApi.shutdown}} method with a parameter of {{Stopped}}. That way, suspending and resuming are much faster.

Tearing down the VM entirely (i.e. {{destroyNode}}) would still always use {{StoppedDeallocated}}.
