Difficulty: HardHigh-Performing and Scalable Storage Solutions

A solutions architect is migrating a high-frequency transactional database to an Amazon EC2 instance. The database requires a single storage volume that can deliver at least 95,00095,000 IOPS and 1.5 GB/s1.5\text{ GB/s} throughput with sub-millisecond latency. The database also requires 99.999%99.999\% volume durability to prevent data loss.

Which actions should the solutions architect take to meet these requirements? (Select TWO.)

  1. Provision an Amazon EBS `io2` volume.Answer
  2. Attach the volume to a supported Nitro-based EC2 instance type.Answer
  3. C
    Provision an Amazon EBS `gp3` volume configured with 95,00095,000 IOPS.
  4. D
    Provision an Amazon EBS `io1` volume configured with 95,00095,000 IOPS.
  5. E
    Attach the volume to a burstable EC2 instance type such as `t3.xlarge`.

Answer

Provision an Amazon EBS `io2` volume and attach the volume to a supported Nitro-based EC2 instance type.
To achieve 95,00095,000 IOPS and 1.5 GB/s1.5\text{ GB/s} throughput with sub-millisecond latency and 99.999%99.999\% durability, the storage must utilize Amazon EBS `io2` volumes on EBS Block Express. This requires provisioning an `io2` volume and attaching it to a supported Nitro-based EC2 instance, which automatically enables the Block Express architecture.

Step-by-Step Solution

1
Identify the volume type that matches the required IOPS, throughput, and durability.
Amazon EBS `gp3` and `io1` volumes do not meet the performance or durability thresholds (with `gp3` limited to 16,00016,000 IOPS and `io1` limited to 64,00064,000 IOPS). Amazon EBS `io2` provides 99.999%99.999\% durability and scales up to 256,000256,000 IOPS on EBS Block Express.
We need to filter out storage volumes that cannot meet the minimum requirements of 95,00095,000 IOPS, 1.5 GB/s1.5\text{ GB/s} throughput, and 99.999%99.999\% durability.
2
Determine the platform configuration required to enable EBS Block Express capabilities.
EBS Block Express is automatically enabled for `io2` volumes when attached to supported Nitro-based EC2 instances (such as `c6in`, `r6in`, or similar compute-optimized/memory-optimized instances).
Standard `io2` volumes on non-supported instances are capped at 64,00064,000 IOPS and will not meet the 95,00095,000 IOPS requirement.
