Microsoft uses Containers (called ITPACs) to build out its data centers. These Containers are Shipping Containers fitted with all the necessary climate control, networking, server racks and other hardware necessary to be a “mini” data center all in one.
An Azure region is a set of data centers deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network.
With more global regions than any other cloud provider, Azure gives customers the flexibility to deploy applications where they need to. Azure is generally available in 46 regions around the world, with plans announced for 8 additional regions.
An Azure geography is a discrete market, typically containing two or more regions, that preserves data residency and compliance boundaries.
Geographies allow customers with specific data-residency and compliance needs to keep their data and applications close. Geographies are fault-tolerant to withstand complete region failure through their connection to our dedicated high-capacity networking infrastructure.
Availability Zones are physically separate locations within an Azure region. Each Availability Zone is made up of one or more data centers equipped with independent power, cooling, and networking.
Availability Zones allow customers to run mission-critical applications with high availability and low-latency replication.
