Difficulty: EasyHigh-Performing and Scalable Storage Solutions

A company hosts a database on a single Amazon EC2 instance. The database requires a 200200 GiB storage volume that must deliver a consistent performance of 10,00010,000 IOPS and 300300 MiB/s throughput. Which TWO actions should a solutions architect take to meet these performance requirements at the lowest cost?

  1. Use an Amazon EBS General Purpose SSD (gp3) volume.Answer
  2. Provision the required 10,00010,000 IOPS and 300300 MiB/s throughput settings directly on the volume.Answer
  3. C
    Use an Amazon EBS General Purpose SSD (gp2) volume.
  4. D
    Use an Amazon EBS Provisioned IOPS SSD (io2) volume.
  5. E
    Use an Amazon Elastic File System (Amazon EFS) file system with Provisioned Throughput.

Answer

Use an Amazon EBS General Purpose SSD (gp3) volume and provision the required 10,00010,000 IOPS and 300300 MiB/s throughput settings directly on the volume.
The correct options are to use an Amazon EBS General Purpose SSD (gp3) volume and to provision the required 10,00010,000 IOPS and 300300 MiB/s throughput settings directly on the volume. Amazon EBS gp3 volumes allow customers to provision storage capacity, IOPS, and throughput independently. This is ideal for workloads like databases that need high IOPS and throughput but have a small data footprint, providing the lowest cost solution.

Step-by-Step Solution

1
Analyze the storage requirements.
The database needs 200200 GiB capacity, 10,00010,000 IOPS, and 300300 MiB/s throughput.
Understanding capacity and performance needs helps in identifying appropriate volume types.
2
Compare Amazon EBS volume types.
Amazon EBS gp3 volumes support independent configuration of capacity, IOPS, and throughput, whereas gp2 ties IOPS directly to capacity (33 IOPS per GiB).
Selecting gp3 allows meeting the high performance target without over-provisioning storage capacity, minimizing costs.
3
Select the correct configuration options.
Configure a gp3 volume with 200200 GiB size, and provision 10,00010,000 IOPS and 300300 MiB/s throughput directly on it.
This configuration satisfies all technical requirements at the lowest cost.

Key Concept

Amazon EBS gp3 volumes support independent scaling of storage capacity, IOPS, and throughput, allowing cost-effective tuning of workloads.
