Zerto cuts EC2 costs by 40% with Zesty’s Cloud Cost Optimization technology

Key Challenges

Zerto’s biggest challenge was forecasting RI usage and manually purchasing various blends of commitments

Key Results

Zerto reduced their EC2 costs by 40%
Zerto engineers no longer need to manually optimize their cloud infrastructure.

The Challenge:
Manual RI forecasting

Forecasting and manually calculating RI’s with different family types, OS flavors, and multiple account owners, was a never-ending challenge for us.

Eventually, Nadav and another IT director understood that their current process is both time-consuming and failed to maximize their savings. So they began searching for a solution that will automate commitment purchases on their behalf. 

Managing our RI fleet manually was occupying me on a daily basis and required frequent follow-ups

Zesty’s Solution:
Maximize RI usage

After a short demo call with Zesty, Nadav connected Zerto’s AWS accounts to see Zesty in action. 

After analyzing and benchmarking their EC2 usage, Zesty’s automated commitment manager began buying and selling RIs in the AWS marketplace and rapidly increased the amount of EC2 instances covered by savings.

Zesty’s automated commitment manager reacts to capacity changes in real-time by analyzing AWS Cloudwatch and Cloudtrail logs. Based this data, it automatically purchases\sells commitments, relieving cloud engineers from spending hours on inaccurate manual forecasting. 

We were amazed by the automatic nature of the platform, which adapts itself on the fly to any type of capacity changes.

As their confidence in the platform increased, Zerto was encouraged to migrate more workloads, and today, all of their AWS accounts are continuously optimized by Zesty.

Zerto was mainly impressed by the simplicity of Zesty’s platform, which enables both technical and non technical users to adopt the product and reap its benefits. 

Zesty provides us the peace we need when it comes to cost optimization, we’re saving money with 0 man-hours invested in the platform

After seeing how much they saved with Zesty’s automated Commitment Manager, Zerto quickly adopted additional features:  

  • EC2 Scheduler – This feature enables Zerto to preconfigure shutdown hours for unused clusters (outside of working hours), which added another pillar to their cost reduction strategy. 
  • S3 Explorer -This featured provides a comprehensive view of all S3 buckets and all of their associated AWS accounts. This allowed Zerto to discover and delete idle buckets, which saved money and helped and resolve potential security risks.

The Result:
Significant Cost

In the eight months since they implemented Zesty, Zerto slashed their EC2 costs by 40%.

The impact of Zesty on our AWS bill was immediate

In addition to significant AWS savings, Zerto’s engineers were relieved from manually calculating RIs which saved them hundreds of man-hours. Best of all, they can rest assured Zesty has them covered 24/7.

The dashboard is clean and informative, and the fact that costs and savings projections update in real-time empowers the organization to be more aware of our ongoing costs
