Difficulty: MediumCompute Virtualization Solutions

A manufacturing corporation is planning the Azure compute architecture for two internal workloads:

- Workload 1: An automated data analysis engine that processes non-critical, interruptible batch jobs. The jobs can be safely restarted if interrupted, and minimizing compute cost is the primary objective.
- Workload 2: A core ERP database application that runs constantly and has strict regulatory requirements specifying that the virtual machines must run on dedicated physical hardware.

Which two compute virtualization solutions should you include in the design?

  1. Azure Spot Virtual Machines to run the data analysis engine.Answer
  2. Azure Dedicated Hosts to run the ERP database application virtual machines.Answer
  3. C
    Azure Spot Virtual Machines to run the ERP database application.
  4. D
    A single Azure Virtual Machine in a single Availability Zone for the ERP database application.
  5. E
    Azure Functions on a Consumption plan to run the data analysis engine.

Answer

The correct compute virtualization solutions are using Azure Spot Virtual Machines to run the data analysis engine and Azure Dedicated Hosts to run the ERP database application virtual machines.
The correct strategy combines Azure Spot VMs and Azure Dedicated Hosts. Spot VMs are designed for workloads that can be interrupted, offering the lowest possible cost for the data analysis engine. Dedicated Hosts provide physical hardware isolation, satisfying the regulatory compliance requirement for the ERP database.

Step-by-Step Solution

1
Analyze the requirements for Workload 1
Workload 1 requires low cost and can tolerate interruptions and restarts.
Identify which Azure VM tier matches interruptible, cost-sensitive batch processing.
2
Select the appropriate option for Workload 1
Azure Spot Virtual Machines are selected for Workload 1.
Spot VMs offer steep discounts (up to 90%) in exchange for the possibility of eviction, which fits the non-critical nature of the workload.
3
Analyze the requirements for Workload 2
Workload 2 requires dedicated physical hardware to meet isolation compliance mandates.
Identify which Azure virtualized compute option provides dedicated physical host-level isolation.
4
Select the appropriate option for Workload 2
Azure Dedicated Hosts are selected for Workload 2.
Azure Dedicated Hosts allocate physical servers to a single subscription, ensuring compliance and physical isolation.

Key Concept

Selecting Azure compute tiers based on cost-efficiency (Spot VMs) versus regulatory and isolation constraints (Dedicated Hosts).
