Zorluk: OrtaCompute Virtualization Solutions

A pharmaceutical company is designing the Azure compute infrastructure to host a molecular modeling simulation application. The simulations run continuously for up to 72 hours. If a virtual machine is interrupted or terminated during a run, the progress is lost, and the entire simulation must restart from the beginning. The application requires high-performance CPU capabilities and low-latency node-to-node communication. The finance team recommends using Azure Spot virtual machines to minimize compute costs. Which compute virtualization strategy should you recommend to meet the requirements of the simulation application?

  1. A
    Deploy the simulation application on H-series Azure Spot virtual machines.
  2. B
    Deploy the simulation application as serverless tasks using Azure Functions on a Consumption plan.
  3. Deploy the simulation application on standard H-series virtual machines.Cevap
  4. D
    Deploy the simulation application on D-series Azure Spot virtual machines.

Cevap

Deploy the simulation application on standard H-series virtual machines.
Deploying the simulation application on standard H-series virtual machines is the correct strategy because H-series virtual machines are optimized for High-Performance Computing (HPC) workloads, providing the necessary CPU performance and low-latency InfiniBand networking. Standard VMs do not have an eviction policy, guaranteeing that the 72-hour simulation runs will complete without interruption.

Adım Adım Çözüm

1
Analyze the workload characteristics and requirements.
The application requires continuous execution for up to 72 hours with no tolerance for interruption, high-performance CPU, and low-latency node-to-node communication.
Identifying these constraints helps filter out compute options that fail to meet availability and performance needs.
2
Evaluate the suitability of Azure Spot VMs.
Spot VMs are rejected because they are subject to sudden eviction, which violates the requirement for uninterrupted 72-hour execution.
Using Spot VMs for critical production or long-running stateful workloads leads to high failure rates due to capacity reclaim.
3
Evaluate the suitability of Azure Functions on a Consumption plan.
Azure Functions are rejected due to the 10-minute maximum execution timeout limit.
Serverless consumption plans are designed for short-lived, event-driven tasks rather than multi-day simulations.
4
Select the appropriate VM series and purchasing option.
Standard H-series VMs are selected because H-series is optimized for HPC (providing InfiniBand networking) and standard pricing ensures no eviction.
This configuration satisfies both the physical networking requirement and the strict availability constraint.
