Zorluk: OrtaCompute Virtualization Solutions

A retail company is migrating its e-commerce inventory management portal to Azure. The portal has the following requirements:

* It must run on virtual machines to support legacy dependencies and custom operating system kernel configurations.
* It must automatically scale the number of virtual machine instances to meet fluctuating traffic demand.
* It must guarantee a Service Level Agreement (SLA) of 99.95%99.95\% for compute availability.
* It must support running a mix of virtual machine sizes (specifically, memory-optimized E-series and general-purpose D-series instances) within the same group to handle different workloads.
* It must distribute the virtual machines across multiple physical fault domains in the Azure region.

Which compute solution should you design to meet these requirements?

  1. A Virtual Machine Scale Set configured in Flexible orchestration modeCevap
  2. B
    A Virtual Machine Scale Set configured in Uniform orchestration mode using Azure Spot Virtual Machines
  3. C
    A Virtual Machine Scale Set configured in Uniform orchestration mode deployed within a single Availability Zone
  4. D
    Azure Functions running on a Consumption plan to host the application pages

Cevap

A Virtual Machine Scale Set configured in Flexible orchestration mode
A Virtual Machine Scale Set in Flexible orchestration mode is the correct design. It allows the integration of heterogeneous virtual machine sizes (specifically memory-optimized E-series and general-purpose D-series) in the same scale set, supports custom images and operating system kernels, automatically scales based on demand, and provides a 99.95%99.95\% availability SLA when virtual machines are distributed across physical fault domains in an Azure region.

Adım Adım Çözüm

1
Analyze the workload requirements for legacy compatibility and OS access.
The requirement to run legacy dependencies and configure custom operating system kernels rules out serverless options such as Azure Functions.
Serverless platforms abstract away the host OS, preventing custom kernel configuration.
2
Evaluate the orchestration mode requirements for Virtual Machine Scale Sets.
Uniform orchestration mode requires identical VM sizes, whereas Flexible orchestration mode allows mixing different VM series (e.g., D-series and E-series) within the same scale set.
The requirement states that a mix of general-purpose and memory-optimized instances must run in the same group.
3
Verify high availability and fault domain requirements.
Flexible orchestration mode guarantees a 99.95%99.95\% SLA when virtual machines are distributed across multiple fault domains in a region.
This configuration meets the SLA and physical fault isolation requirements without relying on Spot instances or single availability zones.
