What Is a Region?
A region in Azure is a geographical area containing at least one datacenter that's networked with a low-latency network.
When you deploy a resource in Azure, you need to choose the region where you want your resources deployed.
Regions are specific areas like West US, Canada Central, West Europe, Australia East, and Japan West.
Each region has its own unique set of resources and services, so it's essential to choose the right one for your needs.
Here are some examples of regions you can deploy your resources in:
- West US
- Canada Central
- West Europe
- Australia East
- Japan West
Paired Regions Benefits
Paired regions in Azure offer several benefits, including physical separation between datacenters, which ensures that your data is held in a secure location. Microsoft rigorously limits physical access to datacenters to protect your data.
Region recovery in the event of an outage is another key benefit of paired regions. If one region becomes unreachable, applications deployed across zones and regions can still be accessed from the paired region.
Automatic platform-provided replication is also enabled in paired regions. Services like Geo-Redundant Storage automatically replicate data to the paired region, ensuring that your data is always available.
Data residency and compliance requirements are also easier to meet with paired regions. Data residency is a compliance requirement that ensures your data is stored in a specific geo-location, which can be important for government compliance or other regulatory requirements.
Sequential system updates are another benefit of paired regions. Azure releases platform updates on a regular basis to enhance the host infrastructure for virtual machines' dependability, performance, and security.
Here are the key benefits of paired regions in Azure:
- Physical separation between datacenters
- Region recovery in the event of an outage
- Automatic platform-provided replication
- Data residency and compliance requirements
- Sequential system updates
Regional Zones
Azure Regions are made up of multiple regions, each containing at least one datacenter. These regions are located in different parts of the world, such as America, Europe, Middle East, Africa, and Asia Pacific.
Azure provides the most extensive global footprint of any cloud provider, with new regions and availability zones being opened rapidly. The following regions currently support availability zones:
Each region is a geographical area containing multiple datacenters, and you need to choose the region where you want your resources deployed when deploying a resource in Azure.

Azure Zones
Azure Zones provide a high-availability offering that protects your applications and data from datacenter failures. This is achieved through unique physical locations within an Azure region, each made up of one or more data centers equipped with independent power, cooling, and networking.
Azure Zones are not available in every region, with examples including Central US, East US 2, West US 2, West Europe, France Central, North Europe, and Southeast Asia. Zone-redundant services replicate your applications and data across Azure Zones to protect from single-points-of-failure.
Using Azure Zones offers an industry-best 99.99% VM uptime SLA, compared to the 22 minutes a month acceptable downtime when using Availability Sets. This is because Availability Zones utilize zone-aware services, opening up your workload across the various zones that compose an Azure region.
What Is Zone?
Availability Zones are physically separate datacenters within an Azure region. Each Availability Zone is made up of one or more data centers equipped with independent power, cooling, and networking. It is set up to be an isolation boundary.

Zone
Azure provides the most extensive global footprint of any cloud provider, with a rapidly expanding list of regions and availability zones. The company is constantly opening new regions and availability zones.
Availability Zones are physically separate datacenters within an Azure region, each made up of one or more data centers equipped with independent power, cooling, and networking. This setup creates an isolation boundary, protecting applications and data from datacenter failures.
Not every region has support for Availability Zones, but some examples include Central US, East US 2, West US 2, West Europe, France Central, North Europe, and Southeast Asia.
Azure Availability Zones protect applications and data from datacenter failures by replicating resources across multiple zones. This ensures high availability and reduces the risk of single-points-of-failure.
Availability Sets are another way to ensure high availability, but they only apply to virtual machines and can't be used for other types of resources. Using an Availability Set takes your acceptable downtime to around 22 minutes a month.
Availability Zones, on the other hand, offer a 99.99% SLA, moving your acceptable downtime to just 5 minutes a month. This is achieved by distributing your workload across multiple zones within an Azure region.
Here's a list of some Azure regions that currently support Availability Zones:

Update Domain and Fault Domain
In Azure, update domain and fault domain are two logical groupings of resources designed to reduce downtime due to hardware or software failures or updates.
Virtual machines get updated domains automatically once they're put inside an availability set.
All virtual machines within that update domain will reboot together to ensure a smooth patching process.
Update domains are used for patching of virtual machines, and only one update domain can be updated at a time.
Here are some key facts about update domains:
- Virtual machines get updated domains automatically once they're put inside an availability set.
- All virtual machines within that update domain will reboot together.
- They are used for patching of the virtual machines.
- Only one updated domain can be updated at a time.
The main difference between fault domain and update domain is that a fault domain is a logical grouping of hardware, whereas an update domain is a logical grouping of resources.
