Headroom Reduction

Meet any spike.
Faster boot time, zero waste.
Accelerate application boot time with Karpenter by up to 5X.
Handle unpredictable usage spikes smoothly, keep CPU buffers lean, and maintain high availability without resource waste.

The Problem

The price of slow scaling
When traffic surges, every second counts.
Even with Karpenter, slow boot times can hurt performance.
The usual workaround is to overprovision replicas, but that leads to low CPU utilization, wasted resources, and inflated cloud costs.
This is exactly what we’re here to solve.

Product Capabilities

Minimize overprovisioning
with precise, faster scaling

Large-scale node
hibernation

Automatically create a pool of hibernated nodes at a fraction of the cost, ready to handle any traffic spike.

5X faster app
boot time

Reduce application boot time to ensure faster response to traffic spikes and greater stability.

Idle pod
reduction

Safely remove idle pod replicas to cut node overprovisioning, optimize CPU utilization, and drive down costs.

Precise prediction
models

Leverage advanced algorithms to analyze historical and real-time utilization patterns, forecast workload demand, and proactively adjust resources.

Workload level
Insights

Gain real-time insights over your workloads’ utilization, costs, and savings opportunities, to reduce CPU overprovisioning and boost cost efficiency.

How It Works

Scale 5X faster to meet any usage surge.

FastScaler™ works alongside Karpenter and Cluster Autoscaler to accelerate application startup time, achieving scale-out up to 5x faster.
By combining hibernation and node pre-warming-caching container images, and pre-starting OS services, it enables horizontal scaling decisions to execute instantly and precisely when demand spikes.

Benefits

When automation meets efficiency

Cut CPU costs

Reduce CPU buffer by up to 70% and stop paying for resources you don’t use, kept just to maintain SLAs.

Ensure app availability

Handle any traffic peak with speed and precision, ensuring your application stays reliable no matter the demand.

Eliminate manual operations

Cut wasted hours of manual prediction, configuration, and monitoring with an automation stack you can trust.

Integrations

Supporting tools that engineering teams love
Whether you’re managing dynamic workloads or scaling clusters, Zesty ensures seamless integration across your Kubernetes infrastructure to reduce overprovisioning and boost efficiency.

How does the pricing model work?

Our pricing model is designed to be straightforward and transparent. We charge a base fee plus a fee per CPU managed by Zesty. Importantly, you’re only billed for the CPU managed after optimization. This ensures that you pay only for the resources we actively manage, delivering clear value with every CPU optimized.

Headroom Reduction supports both Cluster Autoscaler (CAS) and Karpenter, enabling headroom reduction across a wide range of Kubernetes environments.

Yes, security is a priority. The platform complies with industry standards, encrypts all data, and offers role-based access controls, ensuring only authorized users can access your Kubernetes cost data and settings. Only meta-data and usage metrics are collected, Zesty doesn’t have access to any data on the disk or the EC2 instance. These metrics are reported to an encrypted endpoint, and sent unidirectionally to Zesty’s backend. All of Zesty’s architecture is serverless meaning there are no servers or databases involved and all data collected resides within AWS.

Zesty requires an agent with read-only permissions to gain visibility into your environment and provide accurate recommendations. For our automated headroom reduction solution, an additional agent is needed to enhance efficient automation, requiring permissions for creating nodes, reading logs from Cloudwatch, events from SQS, and more.

No, our platform is designed to maintain performance, ensure stability and preserve SLAs, while optimizing costs. Automation keeps CPU available when needed, ensuring applications run smoothly even as costs are reduced.

No, our platform is designed for a quick and simple onboarding process. Most customers are up and running within minutes, with full support to ensure a smooth start on our platform.

Recommendations are available about seven days after connecting a cluster to Kompass. Once a recommendation is activated, headroom reduction is fully automated. Users start seeing measurable savings as early as one hour after activation.
