Zorluk: KolayHigh Availability, Scalability, and Elasticity

A company wants to ensure its web application remains operational even if an entire datacenter in its primary region experiences a power failure. To achieve this, the company deploys virtual machines across separate physical locations within the same region.

Which cloud capability is the company utilizing to meet this goal?

  1. High availability using Availability ZonesCevap
  2. B
    Disaster recovery using multi-region replication
  3. C
    Elasticity using automatic scale sets
  4. D
    Availability Zones that span across multiple geographical regions

Cevap

High availability using Availability Zones
The correct answer is high availability using Availability Zones. High availability ensures that applications remain accessible by hosting them on redundant infrastructure within the same region, such as in separate physical datacenters with independent power and cooling (Availability Zones).

Adım Adım Çözüm

1
Analyze the business requirement
The company wants to maintain application uptime and protect against a power failure in a single datacenter within the same region.
This establishes the scope as localized redundancy (high availability) rather than regional failover (disaster recovery) or dynamic resource resizing (elasticity).
2
Identify the correct cloud concept and architecture component
Deploying resources across separate physical locations (Availability Zones) within the same region provides high availability.
Availability Zones are isolated datacenters within an Azure region designed to protect applications from localized datacenter outages.
