An organization plans to migrate a high-throughput transaction processing database to Azure Virtual Machines. The database transaction log files require high IOPS and consistently low latency. The database architecture must be resilient to the outage of a single datacenter within the primary Azure region. Which disk storage configuration should you recommend for the database transaction logs?

  1. Premium SSD managed disks configured with Zone-Redundant Storage (ZRS)Cevap
  2. B
    Standard HDD managed disks configured with Geo-Redundant Storage (GRS)
  3. C
    Premium SSD managed disks configured with Locally Redundant Storage (LRS)
  4. D
    Standard SSD managed disks configured with Zone-Redundant Storage (ZRS)

Cevap

Premium SSD managed disks configured with Zone-Redundant Storage (ZRS) should be recommended because they satisfy the high IOPS and low latency requirements for database transaction logs while providing zone redundancy to protect against a single datacenter failure in the primary region.
Premium SSD managed disks configured with Zone-Redundant Storage (ZRS) provide the necessary high IOPS and low-latency performance required for database transaction logs, while replicating the data across three separate availability zones within the primary region to survive a single datacenter failure.

Adım Adım Çözüm

1
Analyze the performance requirements of the database transaction logs.
The workload requires high IOPS and low latency, which rules out Standard HDD and Standard SSD tiers.
Database transaction logs are highly sensitive to write latency. Standard storage tiers cannot guarantee the necessary performance.
2
Analyze the resiliency requirements.
The storage must survive a single datacenter outage within the primary region, indicating a requirement for zone-redundancy (ZRS).
Locally Redundant Storage (LRS) keeps data within a single datacenter and cannot survive a datacenter failure.
3
Combine performance and resiliency needs to select the correct disk type and redundancy option.
Premium SSD with Zone-Redundant Storage (ZRS) meets both performance and zone resiliency requirements.
Premium SSD provides the necessary performance tier, while ZRS provides the required availability zone replication.

Anahtar Kavram

Selecting the appropriate disk storage tier and redundancy option based on application performance needs and high availability requirements.
