Resource types

These are an actual resource specification defining it's public API interface and implementation. It implements the working and operations supported by the resource. Similar to resource providers, resource types also evolve over time with regard to their internal implementation and have multiple versions of its schema and public API interface. The version names are based on dates that they are released on by Microsoft as a preview or General Availability (GA). The resource types become available to a subscription after a resource provider is registered to it. Also, not every resource type is available in every Azure region. The availability of a resource is dependent on the availability and registration of a resource provider in an Azure region and must support the API version needed for provisioning it.
