Zorluk: KolayAzure Regions, Availability Zones, and Region Pairs

A company hosts a critical inventory database in the West US 2 region. The database must remain available even if an entire datacenter facility within that region experiences a power outage. The solution must not replicate data to a different geographical region. Which Azure architectural feature should the company use to deploy the database servers?

Cevap

Availability Zones
Availability Zones are physical locations within an Azure region, containing one or more datacenters with independent power, cooling, and networking. This isolation ensures that if one datacenter goes down, other zones in the same region remain online, providing high availability without data leaving the region.

Adım Adım Çözüm

1
Analyze the requirements.
The requirement asks for protection against a single datacenter failure (power outage) within a single region (West US 2) without replicating to a different geographical region.
This helps narrow down the scale of high availability needed (datacenter-level vs. region-level).
2
Evaluate the architectural features of Azure.
Availability Zones provide isolation and redundancy within a single region by grouping datacenters with independent power, cooling, and network infrastructure. Deploying across these zones satisfies both datacenter-level resiliency and regional boundary constraints.
Choosing the correct service tier or feature ensures compliance with architectural and business constraints.
