FAQ - Zesty Disk for Kubernetes

What is Zesty Disk for Kubernetes (K8s)?

Zesty Disk for K8s is an auto-scaling storage solution that dynamically manages Persistent Volumes (PVs) for Kubernetes workloads. It automatically adjusts the size of storage volumes based on actual usage, helping to reduce cloud storage costs and improve resource efficiency.

What Kubernetes environments does Zesty Disk for K8s support?

Zesty Disk for K8s supports Amazon EKS (Elastic Kubernetes Service).

Which workloads does Zesty Disk for K8s support ?

Currently, support is for StatefulSet workloads.

How do I install Zesty Disk in my Kubernetes cluster?

Zesty Disk for K8s is deployed using a Helm chart. For more information, see Deploy Zesty Disk for Kubernetes. Zesty Disk will integrate with your existing Storage classes and begin managing them automatically. Existing PVCs will need to be migrated to work with Zesty Disk for K8s.

What kind of applications benefit most from Zesty Disk for K8s?

The applications that benefit most are those that require dynamic storage management, especially:

• Databases running in StatefulSets (e.g., MySQL, MongoDB)

• CI/CD pipelines that generate large amounts of temporary data

• Big data or analytics applications with fluctuating storage demands

How does Zesty Disk affect Kubernetes performance?

Zesty Disk for K8s is designed to minimize any performance impact. It operates in the background, making volume adjustments without affecting the application’s availability or performance. The resizing operations are triggered based on specific thresholds to avoid unnecessary resource consumption.

By serializing the volumes on the filesystems, Zesty Disk multiplies the number of volumes, thereby increasing overall performance.
