Difficulty: EasyAzure Regions, Availability Zones, and Region Pairs

A retail startup is setting up virtual machines in the East US region. To protect their workloads from localized cooling or power failures at the physical datacenter level within East US, they need to place their virtual machines in different physical locations that have independent power, cooling, and networking.

Which Azure feature should the startup configure to meet this requirement?

  1. A
    Azure Edge Zones
  2. B
    Azure Region Pairs
  3. Availability ZonesAnswer
  4. D
    Resource Groups

Answer

Availability Zones
Availability Zones are unique, physically separate datacenters within an Azure region. Each zone has independent power, cooling, and networking, ensuring that if one zone experiences a localized power or cooling failure, the other zones remain operational.

Step-by-Step Solution

1
Identify the requirement for high availability against localized power, cooling, or network failures at the datacenter level within a single region.
Requires a feature that provides physical isolation of datacenters within the same region.
Locating the exact Azure concept that maps to datacenter-level redundancy within one region.
2
Select the Azure feature designed specifically for physical isolation with independent infrastructure (power, cooling, networking) in the same region.
Availability Zones.
Availability Zones are unique physical locations inside an Azure region that contain one or more datacenters with isolated power, cooling, and networking.

Key Concept

Availability Zones provide high availability by protecting workloads from datacenter outages within a single region.
