  The difference between this builder and the `azure-arm` builder is that this
  builder is able to build a managed disk image without launching a new Azure VM
  for every build, but instead use an already-running Azure VM. This can
  dramatically speed up image builds. It also allows for more deterministic image
  content and enables some capabilities that are not possible with the
  `azure-arm` builder.
  
  > **This is an advanced builder** If you're just getting started with Packer,
  it is recommend to start with the [azure-arm builder](/docs/builders/azure-arm.html),
