There are many options to get a failure on your Azure cloud when you create a VM, restart stopped (de-allocated) VMs, resize a VM, or when you add new web or worker role instances, Microsoft Azure allocates compute resources to your subscription. You may occasionally receive errors when performing these operations even before you reach the Azure subscription limits. An error response always includes a status code and an error object. Each error object always contains an error code and a message. If the VM is created with a template, the error object also contains a details section that contains an inner level of error codes and message. Normally, the most inner level of an error message is the root failure.
