VIRTUAL KUBERNETES
Instantly provision clusters for every Developer
No more Ops headaches or high costs. Virtual clusters launch in seconds, offer better isolation, and scale effortlessly — at a fraction of the cost.
What are virtual clusters?
Virtual clusters are a Kubernetes concept that enables isolated clusters to be run within a single physical Kubernetes cluster. Each cluster has its own API server, which makes them better isolated than namespaces and more affordable than separate Kubernetes clusters.
Lightweight like namespaces
Isolated like separate clusters
Fast to launch like containers
Rethink your Kubernetes architecture with virtual clusters
Maximize the use of your existing Kubernetes clusters. With virtual clusters, you can provision multiple isolated environments on a single cluster, reducing the need for spinning up a new cluster for every team, environment, or customer.
Say goodbye to cluster sprawl and namespace limitations
Unlock faster provisioning, stronger isolation, and significant cost savings. Here’s how virtual clusters outperform both separate clusters and namespaces, giving developers more control and flexibility.
FAST, AFFORDABLE, AND EFFICIENT
Virtual Clusters vs. Separate Clusters
- Provision new virtual clusters in seconds
- 10x cheaper than traditional clusters
- Everyone can get their own isolated K8s cluster
- Put virtual clusters to sleep when idle
- Run fewer duplicates of platform stack tools
ISOLATED, SCALEABLE, AND SECURE
Virtual Clusters vs. Namespaces
- Better isolation, no noisy neighbors
- Full admin access inside virtual clusters
- Better scalability with shared control planes
- High fault tolerance with control plane per tenant
- Reduced attack surface for greater security

PRE-PRODUCTION USE CASES
Empower developers with self-service Kubernetes
Enable developers to access self-service virtual clusters, enhancing autonomy while ensuring security and compliance.
Accelerate CI/CD with ephemeral clusters
Create new virtual clusters for each pull request, enabling fast, isolated testing without waiting or sharing environments.
PRODUCTION USE CASES
Offer private instances to your customers at minimal cost
Quickly spin up one lightweight isolated virtual cluster per customer instead of a heavyweight K8s cluster.
Build a managed K8s service at a much lower cost
Provide customers with dedicated virtual clusters, optimizing node allocation for efficiency and scalability.

How Atlan Reduced Their Infrastructure From 100 Kubernetes Clusters To 1
“vCluster enabled us to turn our single-tenant software product into a multi-tenant platform on top of AWS. We decided to switch to virtual clusters to accelerate the provisioning of new customer instances.”
Yatin Taluja
Director, Cloud
How Ada 10x their development productivity
“Many of our developers are not really familiar with Kubernetes. Our challenge was to enable these developers to test their microservices against the rest of Ada’s software stack without needing to know how Kubernetes really works.”

Manager, Developer Enablement Engineering
How CoreWeave Cloud serves machine learning & AI workloads
“vCluster Pro is the first proven solution for operationalizing virtual Kubernetes clusters at scale and we continue to be impressed by the Loft Labs team and the innovations they ship to customers like us.”
