Difficulty: EasyAWS Compute Optimizer and Right-Sizing

A company uses Amazon EBS gp2 volumes for storage on their EC2 instances. The storage workloads have increased, leading to performance bottlenecks due to IOPS limits. A SysOps Administrator wants to use AWS Compute Optimizer to analyze these volumes and transition them to gp3 to optimize performance and reduce cost. Which of the following actions should the administrator take to achieve this? (Select TWO.)

  1. Opt in to AWS Compute Optimizer at the account or Organization level to analyze EBS volume performance and generate recommendations.Answer
  2. B
    Install the Unified CloudWatch Agent on the EC2 instances to collect and publish custom disk performance metrics.
  3. C
    Create an AWS Budget with a cost trigger to automatically modify the volume type when spending exceeds a threshold.
  4. Use the Amazon EC2 console or AWS CLI to modify the volume type from gp2 to gp3 while the volume remains attached and online.Answer
  5. E
    Configure AWS Trusted Advisor to automatically run remediation scripts that migrate the volumes from gp2 to gp3.

Answer

To analyze the volumes and perform the migration, the administrator must opt in to AWS Compute Optimizer to generate optimization recommendations and then use the EBS Elastic Volumes feature to modify the volume type from gp2 to gp3 while the volumes remain attached and online.
To obtain EBS volume recommendations, the account must be opted in to AWS Compute Optimizer, which automatically evaluates volume utilization metrics. Once recommendations are generated, gp2 volumes can be modified to gp3 online without downtime or detaching the volume using the EBS Elastic Volumes feature.

Step-by-Step Solution

1
Opt in to AWS Compute Optimizer at the AWS account or AWS Organizations level.
AWS Compute Optimizer starts analyzing resource configuration and utilization metrics to generate recommendations for EBS volumes.
Opting in is required to activate the service and enable it to analyze gp2 volumes.
2
Review the recommendations in the AWS Compute Optimizer console to identify gp2 volumes that can be right-sized or migrated to gp3.
The administrator finds recommendations advising migrating specific gp2 volumes to gp3 for cost savings and performance improvements.
This step identifies the exact target volumes and potential performance gains.
3
Use the EC2 Modify Volume action to change the volume type from gp2 to gp3 online.
The EBS volume is modified to gp3 without downtime or detaching it from the instance.
EBS Elastic Volumes allows modification of volume types on-the-fly.

Key Concept

EBS volume optimization using AWS Compute Optimizer and EBS Elastic Volumes online modification.
