Zesty Disk


Block Storage Auto-Scaler

Shrink and expand storage in run time to boost performance and reduce cost by up to 70%



Dynamize your block storage volumes to automatically scale capacity to real-time application needs


Automatic Provisioning of Volumes

Shrink and expand block volumes in line with dynamic and fluctuating application needs, without any human input.

Boost IOPS Performance by 300%

The storage optimizer improves IOPS and throughput performance by as much as 300%, providing direct value to the user experience.


Dramatically Reduce Block Storage Costs

Save up to 70% on block storage costs by eliminating the need to provision excess capacity & having the ability to shrink volumes.


Prevent Filesystem

No more “out of disk” failures
when data ingestion exceeds
the available volume capacity.

How it Works


Cloud Storage

Zesty Disk automatically adjusts your storage capacity to match real-time application needs, achieving the most optimal utilization possible.

Groundbreaking Shrink & Expand Technology

By transforming large filesystem volumes into a virtual disk with a series of multiple volumes, the filesystem can be shrunk and extended automatically.


Improved IOPS & Throughput Performance

Get an IOPS and throughput performance boost by leveraging multiple smaller-sized storage volumes that each have their own burst capacity.

No Data Exposure & Highly Secure Connectivity

Zesty Disk is never exposed to data in storage, only meta-data and usage metrics are collected. When action is taken a command is sent to a dedicated IAM role on the instance.


Use Cases

Zesty Disk automatically shrinks and extends EBS volumes or block storage volumes according to changing app demand. This process involves replacing a large file system volume with multiple small volumes that each have their own IOPS and throughput allocation. Power is aggregated from all of them to provide a performance improvement of up to 300%.

Workloads like databases, ETLs, or ML pipelines that involve high data ingestion requirements can overwhelm storage capacity. But expanding it is almost impossible when working with single servers. With Zesty Disk, you can auto-extend AWS EBS volumes or block storage volumes to accommodate spikes in demand, significantly reducing manual labor.

In order to accommodate peaks demand, customers often provision the highest amount of storage required by their app. Once demand goes back to its normal state, they are unable to scale down, costing them significantly over time. Zesty Disk automatically scales storage volumes up and down according to real-time business demand, so customers only pay for what they need, in some cases saving them up to 70% off storage.

Zesty Disk automatically scales volumes to app demand by adding or removing file system storage according to real-time needs. As a result, you only pay for the capacity you need and can save up to 70% on AWS EBS or other block storage services.

We were looking for a solution that would continuously monitor and optimize our EBS volumes…
The onboarding and value was immediate, and the professional support we received from the team was beyond words… I no longer need to worry about managing EBS volumes, that’s Zesty’s job now”

Frequently Asked Questions

Yes–Zesty Disk uses intelligent automation to dynamically extend block storage to meet real-time app demand. This ensures storage is always optimized while freeing DevOps teams from managing infra. Customers can choose to limit the maximum file system size by creating custom policies in the dashboard and attaching them to their instances.

There is no downtime required when using Zesty Disk to shrink or extend an EBS volume. Instead, Zesty Disk uses a file system technology that can detect and detach excess volumes according to real-time needs. This process happens automatically and doesn’t require human intervention.

While the process of expanding and shrinking the filesystem does consume some resources, there is no direct impact on the instance or the app itself. On the contrary, using Zesty Disk (with or without an auto scaling group) often provides a performance boost with an increase in IOPS (read and write) and throughput.

The usage and metadata metrics that are collected and processed by Zesty’s AI model, generates a behavioral profile on the instance volume. It uses this profile to predict the usage patterns and fluctuations of the disk to ensure that it is perfectly sized in any scenario. Before any change is made a buffer is set that extends the disk by 10-15% of the current volume.

Zesty Disk is not exposed to any data on the disk or in the instance. Nor does it ask for permission to read this data. The system simply collects usage metrics which the AI model analyzes to inform usage predictions.
