Difficulty: EasyAzure Regions, Availability Zones, and Region Pairs

A company is planning to migrate a legacy retail application to Azure. The architecture team needs to ensure the application remains running even if a physical datacenter within the target region experiences a power outage. Evaluate the following statement: Deploying the application's virtual machines across multiple Azure Availability Zones in the same region protects the application from a localized datacenter power failure. Is this statement true or false?

Answer: Answer

Answer

True
Deploying virtual machines across multiple Availability Zones in the same region ensures that if one zone experiences a localized power outage, the other zones remain operational and can handle the traffic.

Step-by-Step Solution

1
Analyze the requirements for resilience against datacenter outages.
The company wants to protect the application from a physical datacenter power outage within a single region.
This is a local disaster recovery and high availability scenario limited to a single region.
2
Evaluate the architectural capability of Azure Availability Zones.
Availability Zones are physically isolated datacenters within a region with independent power, cooling, and networking infrastructure.
Deploying resources across multiple zones ensures that the failure of one zone does not affect the others, protecting the application from localized failures.

Key Concept

Azure Availability Zones are designed to provide high availability within a single region by isolating resources across physically separate datacenters with independent infrastructure.
