Understanding Azure Regions & Availability Zones 🌎

Assume you’re building your home. We wouldn’t put all your valuables in one room, right? You’d spread them out to protect against unexpected disasters. The same principle applies to cloud infrastructure. As much as possible, we always want to account for redundancies.

Azure has 60+ regions worldwide, and knowing how regions, availability zones, and paired regions work is key to designing highly available, resilient applications.

🔹 Regions – Physical locations around the world where Azure data centers are grouped.

🔹 Availability Zones (AZs) – Multiple data centers within a region, each with independent power, networking, and cooling. Deploying across AZs protects against hardware failures.

🔹 Paired Regions – Azure pairs regions (like East US & West US) to enable disaster recovery and minimize downtime during updates.

💡 Why does this matter?

If you deploy a VM in one availability zone and there’s a failure, your app goes down.

If you use multiple AZs, Azure automatically reroutes traffic, keeping things running.

For mission-critical apps, you can replicate across paired regions for geo-redundancy.
