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.

Detailed Explanation

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

1. Small Workload Scenario
   • Current: 1TB gp2 volume
   • Upgraded to: 1TB gp3 volume
   • Estimated Annual Savings: $120-$180
2. 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"
}

# 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
}

Manual Upgrade Steps

1. Snapshot existing gp2 volume
2. Create new gp3 volume from snapshot
3. Detach old volume
4. Attach new gp3 volume
5. 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

1. Database Storage
   • Migrate MySQL database volumes from gp2 to gp3
   • Potential performance improvement with consistent IOPS
2. Development Environments
   • Optimize development and staging infrastructure
   • Reduce storage costs without compromising performance

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
