Kubernetes changed how we build and deploy software, but are you still clinging to virtual machines out of habit? In this post, Scott McAllister walks through the evolution of enterprise computing, from mainframes to microservices, to help you rethink your current infrastructure choices. Is it time to go bare metal?

Traditional multi-tenancy in Kubernetes often leads to complex RBAC, noisy neighbors, and security headaches. This post breaks down why platform teams struggle with namespace-based isolation, and how virtual clusters offer a better path forward.

Discover why enterprises in 2025 are shifting from traditional VMware based virtual machines to modern, Kubernetes-native architectures. Learn how adopting Kubernetes closer to bare metal simplifies infrastructure, reduces costs, and enhances scalability and efficiency.

Well, well, well, KubeCon + CloudNativeCon EU 2025 has come to an end, and we made so many friends and memories! Let's review some of the exciting things our team did at KubeCon: Platinum Sponsors at Platform Engineering Day: The buzz around platform engineering and internal deve...

What about Rancher? Does vCluster work on Rancher? How do we manage virtual clusters on Rancher? Hey, what about Rancher? These are just a few of the questions we have heard over the last couple of years at KubeCon, on the interwebs, and everywhere in between. The answer was alwa...

When we first launched vCluster in 2021, our mission was clear: make Kubernetes multi-tenancy easier, safer, and more cost-efficient. Since then, we've helped organizations around the globe manage Kubernetes with greater flexibility and security. But as Kubernetes usage expanded,...

KubeCon is around the corner, and we at LoftLabs are excited to be back for the 2025 Europe Edition! The projected number of attendees speaks to the scale of the cloud-native landscape, and we’re so excited to mark our presence with talks, activities, and being a proud sponsor. V...

I’m excited to present the updates coming with vCluster v0.24. In this post, we will cover Snapshots and Sleep Mode Improvements. Along with this post, we have a couple of videos that will demo both features. Snapshots Let’s start by talking about Snapshots. While you were always...

The ideal size of your Kubernetes clusters is a day 0 question and demands a definite answer. You find one giant cluster on one end of the spectrum and many small-sized ones on the other, with every combination in between. This decision will impact your organization for years to ...

Multi-tenancy in Kubernetes has been an ongoing challenge for organizations looking to optimize their cloud-native infrastructure. Over the years, the approach to multi-tenancy has evolved, from simple namespace isolation to virtual clusters and, more recently, full-fledged inter...

Kubernetes was designed for efficient resource sharing, but complexity escalates when multiple teams or users step into the same cluster. As organizations scale, the challenge isn't just about running workloads; it's about how those workloads coexist securely and efficiently.

In a fast-paced development environment, having an isolated and ephemeral environment to test changes for every pull request (PR) is a game-changer. In this blog, I’ll walk you through setting up ephemeral PR environments using vCluster, enabling seamless testing of your applicat...
