Improve Application Resiliency with Larger and Faster Amazon EBS gp3 Volumes

Overview

As modern applications scale, maintaining high performance, strong resiliency, and cost efficiency becomes increasingly challenging. Many teams eventually reach the limits of their existing storage architecture and are forced to choose between expensive storage options and complex workarounds such as RAID striping, sharding, or rearchitecting applications.

With the latest enhancements to Amazon EBS gp3 volumes, AWS removes much of this complexity by significantly increasing capacity, IOPS, and throughput limits, while preserving 99.9% durability and keeping pricing unchanged. These improvements allow customers to scale applications confidently without sacrificing resiliency or operational simplicity.

Introduction

Amazon Elastic Block Store (EBS), when paired with Amazon EC2, has long been the backbone of storage for AWS workloads. Over time, AWS has continuously evolved EBS volume types to meet growing customer demands.

Earlier generations, such as gp2, tightly coupled performance to volume size, forcing customers to overprovision storage just to gain throughput. This often led to complex designs that used RAID-0 striping across multiple volumes to meet performance requirements, introducing operational overhead and reducing overall durability.

Purpose of Enhanced Amazon EBS gp3 Capabilities

The newly announced gp3 improvements address three core challenges faced by high-performance workloads:

1. Scaling Without Re-Architecture

Customers can now scale vertically within a single volume rather than striping across multiple volumes, avoiding application redesigns.

2. Improving Effective Durability

RAID-0 striping increases performance but lowers effective durability because the failure of a single volume can result in data loss. Larger gp3 volumes reduce the need for striping, significantly improving overall resiliency.

3. Reducing Operational Complexity

Managing fewer volumes means:

• Less operational overhead
• Easier monitoring and scaling
• Fewer risky migrations when limits are reached

Prerequisites

Before adopting the enhanced gp3 volumes, ensure the following:

• Amazon EC2 instances that support high EBS bandwidth and IOPS
• AWS account permissions to create or modify EBS volumes
• Workloads that can benefit from higher throughput or IOPS
• Understanding of EBS Elastic Volumes for online resizing

No application downtime or interface changes are required.

Implementation Steps

Step 1: Understand the New gp3 Limits

With the latest update, gp3 volumes now support:

• Capacity: up to 64 TiB (previously 16 TiB)
• IOPS: up to 80,000 (previously 16,000)
• Throughput: up to 2 GiB/s (previously 1 GiB/s)

All while maintaining 99.9% durability.

Step 2: Reduce or Eliminate RAID-0 Striping

Previously, achieving high throughput required combining many volumes.
For example:

• gp2 required 16 volumes to reach 4 GiB/s → 98.4% effective durability
• gp3 now achieves similar throughput with 4 volumes → 99.6% effective durability

With larger gp3 volumes, many workloads no longer need striping at all.

Step 3: Create or Modify Volumes

You can create new gp3 volumes or modify existing ones using:

• AWS Management Console
• AWS CLI
• AWS APIs

Simply specify the higher capacity, IOPS, or throughput values, no new parameters or workflows are required.

Step 4: Scale Non-Disruptively with Elastic Volumes

Using Amazon EBS Elastic Volumes, you can:

• Increase volume size
• Increase IOPS or throughput
• Migrate volume types

All without downtime, delaying or eliminating the need for full data migrations.

Step 5: Plan for Future Growth

With the new limits, customers can deploy environments reaching:

• 640 TiB capacity per EC2 instance
• 800,000 IOPS
• 20 GiB/s throughput

These limits exceed the capabilities of most EC2 instances, providing ample headroom for future scaling.

Conclusion

The latest enhancements to Amazon EBS gp3 volumes fundamentally simplify how customers scale high-performance workloads on AWS. By offering dramatically higher capacity and performance limits, without increasing cost or reducing durability, AWS enables teams to:

• Improve application resiliency
• Reduce architectural complexity
• Lower operational overhead
• Avoid premature migrations and redesigns

For both new and existing workloads, gp3 volumes now provide a powerful, cost-effective foundation for growth.
