Zorluk: OrtaAzure Regions, Availability Zones, and Region Pairs

A logistics company is deploying a critical inventory management application in Azure. The application's virtual machines must remain operational if a physical datacenter within their selected Azure region experiences a localized power or cooling failure. Additionally, compliance regulations dictate that all data and virtual machines must remain strictly within the geographical boundaries of this primary region. Which Azure architectural feature should you implement to meet these requirements?

  1. Availability ZonesCevap
  2. B
    Azure Region Pairs
  3. C
    Separate Resource Groups with different locations
  4. D
    Deployment across multiple separate Azure regions

Cevap

Availability Zones
The correct answer is the option specifying Availability Zones. Availability Zones are physically separate locations within a single Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. This design protects the application from localized datacenter failures while fully complying with the requirement to keep all resources within the primary region's geographical boundaries.

Adım Adım Çözüm

1
Analyze the customer's high availability and physical isolation requirements.
The solution must protect against localized datacenter failures (power/cooling outages).
This establishes the need for independent infrastructure zones within a deployment.
2
Analyze the customer's compliance and data residency constraints.
All virtual machines and data must remain within the primary region's boundaries.
This rules out multi-region strategies, including region pairs or geographic distribution.
3
Identify the Azure service that provides datacenter-level redundancy within a single region.
Availability Zones offer isolated datacenters with independent power, cooling, and networking within one region.
This satisfies both the physical isolation requirement and the regional data residency constraint.

Anahtar Kavram

Availability Zones provide high availability and fault tolerance within a single Azure region by isolating physical datacenters.
