Resources are created from resource types and should be unique within a resource group. The uniqueness is defined by the name of the resource and its type together. In OOP parlance, resource instances can be referred to as objects, while resource types can be referred to as a class. The services are consumed through the operations supported and implemented by resource instances. They define properties that should be configured before usage. Some are mandatory properties, while others are optional. They inherit the security and access configuration from its parent resource group. These inherited permissions and role assignments can be overridden for each resource. A resource can be locked in such a way that some of its operations can be blocked and not made available to roles, users, and groups even though they have access to it. They can be tagged for easy discoverability and manageability.
