Zorluk: ZorCompute Virtualization Solutions

A multinational bank is designing the compute virtualization infrastructure for a critical, steady-state financial compliance auditing application. The application has the following requirements:

- Must run continuously 2424 hours a day, 77 days a week (24/724/7) without unexpected evictions or interruptions.
- Must be deployed on physical servers dedicated to a single customer to satisfy hardware isolation compliance rules.
- Must support memory-optimized virtual machines with high memory-to-vCPU ratios.
- Must achieve a minimum compute availability SLA of 99.99%99.99\%.

Which of the following compute virtualization solutions should you recommend to meet these requirements?

  1. A
    Deploy Azure Dedicated Hosts for Ev5-series virtual machines across at least two Availability Zones, and provision Azure Spot virtual machines on these hosts.
  2. B
    Deploy Azure Dedicated Hosts for Ev5-series virtual machines in a single Availability Zone, and provision standard virtual machines on these hosts.
  3. Deploy Azure Dedicated Hosts for Ev5-series virtual machines across at least two Availability Zones, and provision standard virtual machines on these hosts.Cevap
  4. D
    Deploy the compliance auditing application as Azure Functions on a Consumption plan to achieve automated scaling across multiple Availability Zones.

Cevap

Deploy Azure Dedicated Hosts for Ev5-series virtual machines across at least two Availability Zones, and provision standard virtual machines on these hosts.
Deploying Azure Dedicated Hosts provides physical servers dedicated to a single Azure subscription, satisfying the hardware isolation requirement. To achieve a 99.99%99.99\% availability SLA, Dedicated Hosts must be deployed across at least two Availability Zones in a region. Standard virtual machines (such as the memory-optimized Ev5-series) running on these hosts ensure steady-state, continuous execution without the eviction risk associated with Spot instances.

Adım Adım Çözüm

1
Identify the hardware isolation requirement.
Requires the use of Azure Dedicated Hosts to ensure the physical servers are dedicated to a single Azure subscription.
Standard multi-tenant virtual machines do not satisfy the hardware isolation compliance rule.
2
Determine the availability SLA requirement.
Requires deploying the Dedicated Hosts across at least two Availability Zones in the selected Azure region.
An availability SLA of 99.99%99.99\% for virtual machines requires multi-zone deployment. A single zone deployment only provides a lower SLA.
3
Evaluate the workload continuity and eviction constraints.
Requires provisioning standard (non-Spot) virtual machines.
Azure Spot VMs are subject to eviction at any time when capacity is needed, which violates the requirement to run continuously without unexpected evictions or interruptions.
4
Match the compute memory requirement.
Configure Ev5-series virtual machines on the Dedicated Hosts.
Ev5-series virtual machines are memory-optimized and satisfy the high memory-to-vCPU ratio constraint.
