Deploy A Website With Azure Virtual Machines

Azure Virtual Machines are image service instances that provide on-demand and scalable computing resources with usage-based pricing. More broadly, a virtual machine behaves like a server: It is a computer within a computer that provides the user the same experience they would have on the host operating system itself. In general, virtual machines are sandboxed from the rest of the system, meaning that the software inside a virtual machine cannot escape or tamper with the underlying server itself.

    To ensure your services aren't interrupted and avoid a single point of failure, it's recommended to deploy at least two instances of each VM. Do this using a logical feature to ensure that a group of related VMs are deployed so that they aren't all subject to a single point of failure and not all upgraded at the same time during a host operating system upgrade in the datacenter. VMs placed in this feature should perform an identical set of functionalities and have the same software installed.  What is the name of this feature (two word?) [Blank]
