Question

Difficulty: MediumAzure Regions, Availability Zones, and Region Pairs

A game development studio is deploying a multiplayer matchmaking service on Microsoft Azure. The service must remain operational during a localized datacenter power outage or cooling failure within the hosting Azure region.

Does deploying the matchmaking service instances across multiple Azure Availability Zones meet this availability requirement?

Answer: Answer

Answer

Yes, deploying the matchmaking service instances across multiple Azure Availability Zones meets the availability requirement.
Deploying the matchmaking service across multiple Azure Availability Zones satisfies the resiliency goal because each zone possesses independent power, cooling, and networking infrastructure, ensuring a localized datacenter outage does not impact other zones.

Step-by-Step Solution

1
Analyze the service availability requirement.
The service must withstand a localized datacenter power outage or cooling failure within the hosting region.
This defines the scope of the failure as localized to a datacenter infrastructure level.
2
Evaluate the architectural isolation of Azure Availability Zones.
Each Availability Zone is a physically separate location within a region, utilizing independent utility power, cooling, and networking.
This physical separation prevents a localized disaster in one zone from affecting other zones.
3
Determine the outcome of deploying across multiple zones.
Since the zones are isolated, a power or cooling failure in one zone leaves the instances in the other zones unaffected, maintaining service availability.
This directly fulfills the resiliency requirement.

Key Concept

Azure Availability Zones provide datacenter-level fault isolation within an Azure region through independent power, cooling, and networking infrastructure.
