Difficulty: EasyCompute Virtualization Solutions

A logistics company is designing the Azure infrastructure for a new core order-tracking application. The application will run on Azure Virtual Machines, requires a 99.99%99.99\% availability SLA, and must remain operational even if a primary datacenter within the Azure region experiences a power outage. Which virtualization deployment strategy should you recommend?

  1. Deploy standard Azure Virtual Machines distributed across multiple Availability Zones in the region.Answer
  2. B
    Deploy standard Azure Virtual Machines grouped within a single Availability Zone.
  3. C
    Deploy Azure Spot VMs distributed across multiple Availability Zones.
  4. D
    Deploy a single standard Azure Virtual Machine using standard HDD storage.

Answer

Deploy standard Azure Virtual Machines distributed across multiple Availability Zones in the region.
Deploying standard virtual machines across multiple Availability Zones provides independent physical locations within a region, protecting the application from datacenter-level power outages and enabling a 99.99% SLA.

Step-by-Step Solution

1
Analyze the availability and disaster resilience requirements.
The application requires a 99.99% availability SLA and must survive a power outage at a primary datacenter.
This rules out single datacenter (single zone) deployments and single VM solutions.
2
Evaluate the workload stability requirements.
The application is a core order-tracking system, representing a steady-state production workload.
This rules out Azure Spot VMs due to the risk of eviction.
3
Select the appropriate deployment architecture.
Deploying standard virtual machines across multiple Availability Zones provides zone redundancy and satisfies the 99.99% SLA.
Availability Zones physically isolate workloads across separate datacenters with independent power, cooling, and networking within a region.
