How To Choose The Right Azure Paired Region For Cloud Services

Posted by Sas Chatterjee on Oct, 12, 2022 04:10

Microsoft Azure has a lot of built-in redundancy, which allows your data to survive an outage. Each Azure paired Region is made up of several structures or data centers. The number of data centers within each Region varies depending on the size of the Region. The smallest Azure regions can support up to five data centers, while the largest Azure regions can support up to 30 data centers.

Each data center within an Azure Paired Region supports three copies of any data you store within that location. This redundancy means that if there is some issue with one or more buildings in a particular location, you will still be able to access your data via another building in the same Region or a different location altogether.

Why Azure Paired Regions Are An Important Factor In Cloud Solution Planning

When it comes to cloud solutions, nothing is more important than choosing the right Azure region pair. While you shouldn’t just concentrate on technology to the exclusion of finding solutions to your business’s problems, there are some technical questions we can address upfront for every project.

We want to make sure that your solution is made to promote the best results for your business. Pairings of Azure regions are one of these factors to consider, yet they are frequently disregarded.

Early consideration of Azure Paired Region may guarantee that your business receives all the benefits that will improve service delivery, reduce latency concerns, increase agility, and better control costs.

We can help you whether you’re attempting to boost creativity and agility using Microsoft Azure cloud, reduce expenses, or create operational efficiency. In partnership with you, we use this cloud solution to help you manage application and infrastructure difficulties, introduce new income streams, and boost productivity.

Key Advantages Of Azure Paired Region

Microsoft region pairing delivers five main advantages:

  • Services for location-specific storage automatically duplicate between neighboring regions. This implies that you may stop worrying about data loss or corruption because all of your data is copied to the same physical place. Additionally, you can regulate the access and manage prices across all locations while managing your storage resources from a single perspective.
  • Microsoft staggers planned maintenance across region pairings so that identical maintenance action does not occur for Azure Paired Region in a given pair at the same window. This makes it simpler to arrange maintenance ahead of an outage, lessening the harmful effects of downtime on your company’s operations.
  • To support regional data replication prevalent in DR solutions, region pairs include more significant capacity network backbone links between each area in the pair. This makes it possible to guarantee that your data will always be accessible, regardless of where it is globally.
  • Although it may not be feasible or viable in all regions, Azure wants at least 300 miles to separate data centers in a regional pair. Physical data center separation decreases the possibility of calamities, unrest, power failures, or physical network disruptions simultaneously striking both areas.
  • Recovery of one area out of each pair is given priority in the case of a widespread outage. Programs operated across Azure Paired Region will always receive priority recovery for one of the regions. You may delay recovery if an application is spread over unpaired areas; in the worst scenario, the selected regions might be the last two to be restored.

How Microsoft Azure Regions Help You Survive Outages

For each Azure location, Microsoft Azure refers to an “Azure Region” rather than an “Azure datacenter.” Every Azure Region is formed of many structures or data centers. Because each Azure area is the size of a city block, there is much redundancy inside each physical place, which is why I bring it up.

That is because every Azure Region retains three copies of whatever data you save there. As a result, your data is often spread out among several structures in the Region. The likelihood is that because of the built-in redundancy. Your access would not be interrupted if outages were inside an Azure Paired Region.

Microsoft has been operating in the cloud for many years and has survived outages due to its ability to mirror data across multiple sites and storage systems. 

With Microsoft’s approach towards virtualization and cloud computing, they have been able to make sure that their customers are protected from downtime by creating redundant hardware infrastructure at all levels: physical hardware that sits onsite or in remote locations (such as farms or data centers) as well as software infrastructure running.


How Geography Impacts Azure Availability Zones

The most important factor when selecting a location for your Azure Availability Zones is the network latency between your physical location and the Azure Paired Region you are considering. The closer the latency, the better your experience will be. A nearby Azure Region can be preferable if you want to rebuild your on-premises infrastructure because it will have the lowest network latency between your actual location and Azure.

Consider an Azure Region further from your actual location if you want to use Azure as a disaster recovery site since it will offer more geographic diversity at a cheaper cost. Politics may also influence how you choose your Azure Region. Some businesses prefer not to retain their data in political contexts other than their own.  

Make sure you consider the data access laws in the nations hosting the Azure Paired Region you are considering because each country has its regulations surrounding government access to data. Typically, US businesses prefer to retain their data inside the US, Canadian businesses want to keep their data inside Canada, and European customers want to keep their data inside Europe.

How Availability Zones Work In Microsoft Azure

Microsoft Azure provides availability zones for customers that need to run mission-critical applications with high availability and low-latency replication. Availability zones are geographically distinct areas inside an Azure region.

One or more data centers with separate power, cooling, and networking make up each availability zone. It is designed to act as a separation barrier. The other availability zone keeps operating even if one goes down.

Usually, extremely fast, proprietary fiber-optic networks link the availability zones together. As a result, customers may operate mission-critical applications in availability zones with high reliability and low-latency replication.

Azure provides availability zones as a service to provide resilience, and there are at least three different zones in each enabled area. In addition, the Central US, North Europe, Southeast Asia, and other areas provide Availability Zones.

EPC Group Offers Microsoft Azure Consulting Services

This blog should assist you in choosing the ideal Azure paired Region for your cloud services. As a whole, Microsoft’s transparent approach to Azure paired regions can be both a blessing and a curse. The ability to quickly plan for an outage and reroute resources are excellent features of Azure paired regions. However, the inability to view service endpoints and data separately makes this feature more of a tool for administrators than anyone looking to set up their services.

We recommend starting with our EPC Group Azure Consulting IT Services to help you choose the best Region for your needs. Our experts can help ensure that your applications are running at peak performance before migrating them over to Azure. In addition, Microsoft Azure offers several cloud services to help you meet your business goals. We have some tips and recommendations if you’re looking to migrate your workloads over to Azure!
