Why sharding etcd doesn’t scale, and how virtual clusters eliminate control plane bottlenecks in large Kubernetes environments.

OpenAI’s outage revealed what happens when etcd breaks at scale. This post explains why sharding isn’t enough, and how vCluster offloads API load with virtual control planes. Benchmark included.

Why Namespace Isolation Falls Short for GPU Workloads, and How Multi-Tenancy with vCluster Solves It

Managing AI workloads on bare metal Kubernetes with GPUs presents unique challenges, from weak namespace isolation to underutilized resources and operational overhead. This blog explores the pitfalls of namespace-based multi-tenancy, why running a separate cluster per team is expensive, and how vCluster enables secure, efficient, and autonomous GPU sharing for AI teams.

Compare vCluster and HyperShift to understand which solution delivers better multi-tenancy, efficiency, and compatibility in Kubernetes environments.

As platform engineering teams scale Kubernetes adoption, choosing the right multi-tenancy model becomes crucial. This article compares Red Hat's HyperShift and Loft Labs’ vCluster, highlighting the trade-offs in resource usage, ecosystem compatibility, portability, and vendor lock-in. Learn why vCluster’s lightweight, upstream-native approach is often better suited for modern internal platforms.

Enable multi-tenant Kubernetes service mesh with zero sidecars and seamless Istio integration using Ambient Mode and vCluster.

The v0.25 release of vCluster brings native support for Istio’s Ambient Mesh, enabling shared service mesh capabilities across multiple virtual clusters without sidecars. This update dramatically reduces resource overhead, simplifies operations, and boosts scalability in multi-tenant Kubernetes environments.

KubeCon India 2024 - Yashobhoomi, New Delhi

So, it finally happened! The first-ever KubeCon in India took place at Yashobhoomi, Delhi, on the 11th and 12th of December! Loft Labs was proud to be one of the sponsors for this historic event. The excitement and enthusiasm I witnessed were next level. There were so many WOW mo...

Introducing Loft v3: Enhanced multi-tenancy, GitOps integration, and a revamped UI for streamlined Kubernetes platform management.

Introducing Loft v3

Integrating Loft and Argo CD to streamline Kubernetes delivery pipelines with enhanced multi-tenancy and GitOps workflows.

About five years after Jez Humble and David Harley released their book on Continuous Delivery, Kubernetes entered the public stage and with it, a new way to think about server management hit the mainstream. Instead of defining what needs to be done to get a server into the desire...

Streamline your Kubernetes platform management by provisioning Loft Spaces and Virtual Clusters using Terraform.

A look at Loft’s new Terraform provider, which allows users to use Terraform to configure Loft Spaces and Virtual Clusters.

We’re excited to announce that Loft v2 has shipped. v2 is a set of improvements that we think makes Loft even easier to use and more powerful.

Keeping Kubernetes costs under control is challenging, especially with idle resources and unused clusters. This blog explores how Loft's Sleep Mode automatically scales down inactive workloads, saving on cloud costs and reducing environmental impact. Learn how to set up and manage Sleep Mode to optimize your Kubernetes infrastructure.

Explore the future of Kubernetes multi-tenancy with insights into virtual clusters presented at KubeCon North America 2021.

At KubeCon North America 2021, Loft Labs CEO Lukas Gentele presented "Beyond Namespaces: Virtual Clusters are the Future of Multi-Tenancy," highlighting how virtual clusters address the challenges of shared Kubernetes environments. Additionally, Razorpay's Srinidhi S and Venkatesan Vaidyanathan shared their experience in enhancing developer workflows using tools like Telepresence, Helm, and vCluster.

Understanding the motivations behind the widespread adoption of internal Kubernetes platforms for enhanced developer productivity and operational efficiency.

Several factors drive more and more companies to develop and adopt internal Kubernetes platforms for their engineers. In this article, we explain these factors.

Enhance development workflows with realistic Kubernetes sandbox environments for efficient testing and collaboration.

Discover how Kubernetes sandboxes, whether local or shared, can improve software quality by providing isolated environments that mirror production systems, facilitating early validation and reducing bugs.

Empower developers with on-demand Kubernetes namespaces to accelerate adoption, enhance productivity, and reduce operational bottlenecks.

Having Kubernetes self-service namespace platform will help you to take the next step towards Kubernetes adoption at your organization.

Empower your engineering teams with a self-service Kubernetes platform to streamline development workflows and enhance productivity.

Discover how to build an internal Kubernetes platform that enables developers to create and manage their own namespaces, reducing operational overhead and accelerating development cycles. Learn about the benefits of self-service environments, improved resource utilization, and enhanced developer autonomy.

We're proud to announce that loft is the first cloud-native technology that ships a stable implementation for virtualized Kubernetes clusters. With loft v0.3, users are now able to create virtual Kubernetes clusters (vClusters) in a matter of seconds either via a click on the UI,...

Cloud costs can spiral with Kubernetes, but you can save over 60% by sharing clusters and using sleep mode for unused resources. Learn how tools like Loft make Kubernetes more affordable for all organizations.
