The need for scalable and efficient Kubernetes cluster management has never been greater.

Traditional cluster setups come with their own set of challenges, but now there’s a groundbreaking solution — Loft’s Virtual Clusters.

In this article, we’ll embark on an exciting journey to understand how Loft Virtual Clusters work and explore their numerous advantages compared to traditional clusters.

So, fasten your seat belts and get ready to dive into the world of virtual clusters with Loft!

The Rise of Loft Virtual Clusters

Before we delve into the specifics, let’s set the stage by understanding why Loft Virtual Clusters have gained immense popularity.

Traditional Kubernetes clusters often lack flexibility and limit on how easily you can offer multi-tenancy for more advanced use cases.

Non-namespaced resources (CRDs, WebHooks, StorageClasses, etc) are often used by Kubernetes Tooling applications and can very easily come into conflict with each other.

Some tooling is even tied to specific Kubernetes Versions and their resources, meaning you need to keep both Kubernetes and Tooling versions “in sync” to avoid issues.
