Azure was announced in 2008 and publicly released in 2010 after earlier experiments in cloud computing like Whitehorse and RedDog. In fact, references to the "classic" model predating the Azure Resource Manager (ARM) actually refer to RedDog: the "classic" portal was also known as "RedDog Front-End".

A pattern common to Azure is that of a service being implemented in two resource types, one of which determines important configuration settings shared by all instances of the service which are contained within it.

Service	Meta-resource	Inner resource	Description
Dedicated Host	Host group	Host	Dedicated hosts are implemented in host groups, which determine available fault domains, availability zones, and other options for hosts.
App Service	App Service Plan	App Service (Web App)
Backup	Recovery Services Vault	Backup items
