Resource providers

These are services responsible for providing resource types through Azure Resource Manager. The top-level concept in the ARM is resource providers. These providers are containers for resource types. Resource types are grouped into resource providers. They are responsible for deploying and managing the resources. For example, a virtual machine resource type is provided by a resource provider called Microsoft.Compute Namespace. The REST API operations are versioned to distinguish between them. The version naming is based on the dates on which they are released by Microsoft. It is necessary that a related resource provider is available to a subscription to deploy a resource. Not all resource providers are available to a subscription out of the box. If a resource is not available in the subscription, one must check if the required resource provider is available in each region. If that is available, the user can explicitly register in the subscription.
