Zorluk: Çok zorCompute Virtualization Solutions

An enterprise plans to migrate a mission-critical, stateful database application to Azure. The application has the following requirements:
- Strict regulatory compliance mandates physical isolation at the hardware level, ensuring no other customer workloads run on the same physical host.
- The database is highly memory-intensive, requiring a memory-to-vCPU ratio of at least 8:1.
- The transaction log storage requires at least 80,000 IOPS with consistent sub-millisecond latency.
- The compute infrastructure must achieve a 99.99% availability service level agreement (SLA).
- The solution must support Azure Hybrid Benefit to minimize licensing costs.

Which compute and storage architecture should you recommend to meet these requirements?

  1. Deploy Azure Dedicated Hosts using the Ebsv5-series host group across two Availability Zones, deploy the database Virtual Machines on these hosts, and configure Premium SSD v2 storage for the transaction logs.Cevap
  2. B
    Deploy standard multi-tenant Ebsv5-series Virtual Machines in an Availability Set, configure Standard SSD storage for the transaction logs, and apply Azure Hybrid Benefit at the individual Virtual Machine level.
  3. C
    Deploy Azure Dedicated Hosts using the Ebsv5-series host group within a single Availability Zone, deploy the database Virtual Machines on these hosts, and configure Premium SSD v2 storage for the transaction logs.
  4. D
    Deploy Azure Dedicated Hosts using the Ebsv5-series host group across two Availability Zones, deploy the database Virtual Machines as Azure Spot Virtual Machines on these hosts, and configure Premium SSD v2 storage for the transaction logs.

Cevap

Deploy Azure Dedicated Hosts using the Ebsv5-series host group across two Availability Zones, deploy the database Virtual Machines on these hosts, and configure Premium SSD v2 storage for the transaction logs.
Deploying Azure Dedicated Hosts using the Ebsv5-series host group provides physical isolation at the hardware level, satisfying regulatory compliance. The Ebsv5-series is memory-optimized, meeting the required memory-to-vCPU ratio. To achieve the 99.99% availability SLA, the Dedicated Hosts must be deployed across at least two Availability Zones in the same region. Finally, Premium SSD v2 storage supports the required 80,000 IOPS with sub-millisecond latency, and Dedicated Hosts support host-level Azure Hybrid Benefit for license cost optimization.

Adım Adım Çözüm

1
Evaluate the requirement for hardware-level isolation and Azure Hybrid Benefit.
Determine that Azure Dedicated Hosts are necessary.
Standard multi-tenant VMs do not guarantee hardware isolation, whereas Dedicated Hosts provide physical servers dedicated to a single subscription and support licensing at the host level.
2
Select the appropriate compute series and storage configuration for high performance.
Select Ebsv5-series VMs and Premium SSD v2 storage.
The database needs an 8:1 memory-to-vCPU ratio (satisfied by the memory-optimized E-series) and a storage solution supporting 80,000 IOPS with sub-millisecond latency (satisfied by Premium SSD v2).
3
Configure the deployment architecture to meet the target availability SLA.
Distribute the Dedicated Hosts across at least two Availability Zones.
To achieve a 99.99% VM availability SLA when using Azure Dedicated Hosts, the hosts must be deployed in different Availability Zones within the same region.
