XM-Cyber Leverages Zesty to automatically right-size EBS volumes for effortless cost reduction

Key Challenges

XM-Cyber’s main challenge was automatically right-sizing their EBS volumes in order to prevent EBS failure

Key Results

XM-Cyber no longer needs to monitor their EBS volumes, Zesty automatically expands their disk once it reaches a certain threshold, enabling them to only pay for storage they actually use.

The Challenge:
Manual EBS expansion

XM-Cyber’s journey with AWS began several years ago, and today, their environments consist of hundreds of EC2 instances for DEV and Production.

In order to support its continuous growth, XM-Cyber required an elastic infrastructure that could easily scale according to customer\POC onboarding. As their infrastructure grew larger, so did their AWS bill.

To save on AWS, XM-Cyber implemented Zesty’s Commitment Manager to manage their RI fleet automatically. Even though they managed to reduce their EC2 costs by over 35%, they were still struggling to automatically right-size their EBS volumes, a major contributor to cloud waste.

To prevent EBS failure (a status in which the EBS is out of storage space), engineering teams usually overprovision EBS volumes by at least 80% of their actual usage, contributing to tremendous cloud waste. 

We were looking for a solution that would continuously monitor and optimize our EBS volumes

Zesty’s Solution:
Automated EBS right-sizing

To solve this issue, XM-Cyber implemented Zesty’s EBS auto-scaler. The EBS auto-scaler continuously analyzes utilization trends across all EBS volumes and automatically right-sizes storage volumes according to real-time usage.

This means that once an EBS volume reaches a certain threshold of disk utilization, Zesty will automatically expand or shrink the disk by a predefined amount of GB, in order to prevent EBS failure and reduce costs.

This allows engineers to provision storage volumes according to actual usage, rather than overprovisioning as a precautionary measure.

With Zesty’s EBS auto-scaler, XM-Cyber’s DevOps engineers are provisioning their EBS volumes with the minimum amount of storage needed to run their workloads.

I no longer need to worry about managing EBS volumes, that’s Zesty’s job now

The Result:
‘Hands-free’ EBS optimization

Since XM-Cyber onboarded Zesty’s EBS auto-scaler, they benefited from:


  • 60% less spend on EBS
  • Full visibility into EBS volumes 
  • 0 EBS failures 
  • Real-time EBS monitoring system 

Best of all, with Zesty, they could rest assured that they’d always maximize cloud savings with zero effort from their team.

The onboarding and value was immediate, and the professional support we received from the team was beyond words
