How it Works


Automated Optimization
in Real-Time

Commitment Manager collects usage performance metrics from real time data sources, this enables rapid adjustments of RI commitments to changing demand.


EC2 Savings on Auto-pilot

Responsive to your application’s needs, when usage scales up, it automatically buys RIs, and when usage scales down, RI’s are sold off.


Zero Engineering Effort

A seamless and non-intrusive process that doesn’t require any agent integration on the EC2 instance, but set permissions to access AWS Cost Explorer.

But wait, there's more...

Highly Secure Connectivity

Access to AWS Cost-Explorer is only through IAM role authentication for which external ID needs to provide two-factor authentication.

Success Based Pricing Model

Only pay a percentage of the amount you save, month to month. No commitment. No setup fee.

Buy-back Guarantee

We are so confident in our technology, that we will reimburse you for any
over-provisioned RIs.

Use Cases

Zesty dynamically buys and sells AWS Reserved Instances according to real-time application needs so you never need to choose between paying for expensive On-Demand Instances or over-provisioning and paying for discount commitments that you don’t use. Offering the flexibility of On-demand with the discounted pricing structure of RIs, you can realize top savings without the commitment. 

Many companies miss out on AWS cost savings available through discount commitments due to vendor lock-in and the financial and operational risk of being unable to adjust cloud infrastructure for up to one or three years as required with discount offerings like Reserved Instances. Commitment Manager eliminates vendor lock-in by matching RIs to EC2 usage, without any long-term commitment.

Relieve Cloud Engineers from monitoring, reviewing, and adjusting Amazon Web Services discount commitments by having your Reserved Instances automatically adjusted in line with your application needs. Commitment Manager uses real-time data to enable rapid Reserved Instance adjustments which scale alongside changing demand, providing greater coverage with zero effort.

The instantaneous and responsive scalability offered by Commitment Manager enables organizations to migrate their infrastructure in and out of AWS without being restrained by vendor lock-in. As infrastructure is moved in they can immediately benefit from Reserved Instance discounts and as infrastructure is moved out, users are not restrained by long-term commitments.

Frequently Asked Questions

Commitment Manager does not require an agent nor does it touch your AWS EC2 instances. Zesty requires an IAM role to be set up and linked to the Zesty dashboard as well as registration to the RI Marketplace. With these limited permissions our AI algorithms are able to analyze AWS usage data and send commands for buying and selling  Reserved Instances.

Yes, Zesty can further reduce AWS costs if you’re already using discount offerings. It can be used to reduce the number of instances running On-Demand, cover the remaining delta of instances that are not on discounts, save on expiring commitments, and more. See your savings potential in minutes with a POC onboarding. 

Our mission is to help you make your AWS infrastructure more cost effective without any long-term commitment. Therefore, you do not need to commit upfront to a specific period of time when signing a contract with us. However, we do require 30 days written notice in order to cancel our service.

The full Zesty solution offers a number of insights and tools for AWS cost optimization.

  • S3 Explorer: Provides visibility into all S3 buckets and their associated costs.
  • EC2 Scheduler: Set a turn on/off cycle for instances to schedule their operation.
  • Unused Instances: Identifies monthly waste associated with detached EBS volumes, ELBs and EIPs.

We cover Kubernetes and containerized workloads in addition to Amazon EC2. Since AWS gives better discounts for Linux, you’ll get the best value if 50%+ of your workloads are Linux. Some limitations exist on the types of instances and regions that can be covered, this is due to their relative low availability and liquidity within Amazon Web Services.
