Amazon EBS – Consider Upgrading gp2 Volumes to gp3

gp3 volumes represent the latest generation of general-purpose SSD-based Amazon EBS volumes that provide enhanced flexibility and cost-efficiency for cloud storage. By enabling performance provisioning independent of storage capacity, these volumes offer a strategic opportunity for organizations to optimize cloud infrastructure spending.

Why This Policy Matters

• Cost Optimization: gp3 volumes can reduce storage costs by up to 20% compared to gp2 volumes

• Performance Flexibility: Independent scaling of IOPS and throughput without additional storage capacity

• Granular Control: More precise performance configuration options

• Modern Cloud Infrastructure: Aligns with best practices for cloud resource management

Cost Reduction Mechanics

Organizations can achieve significant cost savings through gp3 volume upgrades by:

Reducing per-GB pricing

Eliminating overprovisioning of storage

Optimizing performance-to-cost ratio

Implementing more granular resource allocation

Potential Savings Examples

Small Workload Scenario

Current: 1TB gp2 volume

Upgraded to: 1TB gp3 volume

Estimated Annual Savings: $120-$180

Medium Enterprise Scenario

• Current: 50 x 1TB gp2 volumes

• Upgraded to: 50 x 1TB gp3 volumes

• Estimated Annual Savings: $6,000-$9,000

Implementation Guide

Infrastructure-as-Code Upgrade (Terraform Example)

Before (gp2 volume)

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp2"
}

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp2"
}

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp2"
}

After (gp3 volume)

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp3"
  iops              = 3000    # Optional custom IOPS
  throughput        = 125     # Optional throughput
}

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp3"
  iops              = 3000    # Optional custom IOPS
  throughput        = 125     # Optional throughput
}

resource "aws_ebs_volume" "example" {
  availability_zone = "us-west-2a"
  size              = 1
  type              = "gp3"
  iops              = 3000    # Optional custom IOPS
  throughput        = 125     # Optional throughput
}

Manual Upgrade Steps

Snapshot existing gp2 volume

Create new gp3 volume from snapshot

Detach old volume

Attach new gp3 volume

Validate performance and data integrity

Best Practices

• Conduct thorough performance testing before full migration

• Use Infracost to identify and prioritize volume upgrades

Start with non-critical workloads

Monitor performance metrics during transition

Tools for Implementation

AWS CLI

Terraform

Infracost (for comprehensive cost analysis and policy enforcement)

Example Scenarios

Database Storage

• Migrate MySQL database volumes from gp2 to gp3

Considerations and Caveats

Potential Limitations

• Not all workloads benefit equally from gp3

• Some legacy applications might require specific configuration

• Initial migration effort and potential brief downtime

Performance testing is crucial

When to Avoid Upgrading

• Highly specialized workloads with unique I/O patterns

• Systems with strict compliance requirements

• Environments with complex storage configurations
