↑ 5%The AI infrastructure bottleneck: why 'good enough' Kubernetes isn't cutting it anymore. While security eyes are on the RSAC conference in San Francisco this week, the compute world is focused on KubeCon EU in Amsterdam. But the theme of artificial intelligence is the pervasive across both, as in enterprise information technology we've reached a point where "AI curiosity" has officially been replaced by "AI urgency." Every chief information officer I talk to is under immense pressure to move from those neat little research-and-development experiments to actual production-grade deployment. But as they scale, they're hitting a wall that isn't about the models or the data - it's about the plumbing. Specifically, it's the graphics processing unit infrastructure bottleneck. For years, we've treated Kubernetes as the panacea to infrastructure woes. Need to scale? Throw it in a container. Need to orchestrate? K8s is your friend. But when you're dealing with Nvidia Corp. Blackwell B300s and massive training clusters, the standard way of doing things is sharing overprovisioned environments or waiting weeks for dedicated hardware. These are recipes for project failure, only adding to the narrative that the majority of AI project fail. Today at KubeCon, neocloud provider QumulusAI and vCluster, creators of virtual Kubernetes cluster technology, announced a partnership to address much of the friction between infrastructure agility and the rigid demands of high-performance GPUs. The real cost of infrastructure friction. Today's reality is that enterprise development teams are currently stuck in a "pick your poison" scenario. * The wait-and-see approach: A dedicated GPU environment is requested, but the IT team needs time to provision and tells the requester to check back in three weeks. In the past, this has been an annoyance but in the AI race, three weeks is an eternity and could be the difference in being an industry leader or a laggard. * The Wild West approach: Business units share a massively overprovisioned environment. It's faster to get into, but it's a security nightmare, and resource contention makes training runs highly unpredictable and ever harder to forecast when attempting to capacity plan. This inefficiency is more than just an inconvenience; it's a massive drain on return on investment, since time is money. When companies deal with hyperscalers or neocloud providers, they expect the kind of speed that Nvidia Blackwell B300s and RTXPRO 6000s promise. Having those chips sit idle while a developer fumbles a namespace configuration is the compute version of malpractice. QumulusAI and vCluster: partitioning power. The partnership between QumulusAI and vCluster brings customers a way to "slice and dice" high-end GPU power without the overhead of traditional virtualization. This gives customers more options but more importantly, the exact amount of GPU power they need to run their accelerated computing workloads, the primary one being AI. QumulusAI came to market with a value proposition of building a turnkey, vertically integrated AI cloud. Think of QumulusAI as a company that didn't just build a fast car, but designed the engine, the fuel and the highway it runs on. This "hyperspeed compute" setup provides massive power, but QumulusAI also provides the dashboard to keep all the horsepower under control. In fact, the company will let customers only use a piece of the engine if that's all that's required for the journey. By integrating vCluster's virtual Kubernetes technology, QumulusAI is essentially giving enterprises faster and more granular control of isolated environments. Instead of spinning up an entire physical cluster for every project, which is slow and expensive, teams can now spin up isolated virtual clusters on shared GPU hardware. This gives developers the "feel" of a dedicated environment - complete with their own application programming interface server and full control - while the platform team gets to maximize the utilization of those incredibly expensive GPUs. The vCluster AI Lab: innovation at the edge. Perhaps the most interesting part of this news is the launch of the vCluster AI Lab. The lab should provide QumulusAI customers assurance they can continue to use the platform for the long term. As the physical chips that are used for AI, such as GPUs, rapidly improve, the software managing them must stay ahead of the curve. This lab ensures that no matter how advanced the hardware becomes, the systems can handle the workload. It allows vCluster engineers to prototype how Kubernetes should handle emerging AI workloads in real time. Accelerating the move to AI factories. As I've noted in my previous posts, in 2026 the goal for companies should be to move AI factories from being projects to production infrastructure. To get there, organizations need three things: * Access: Getting the latest silicon (such as the B300) without a two-year lead time. * Isolation: Ensuring that Team A's training run doesn't crash Team B's inference model. * Speed: Moving from idea to environment in minutes, not months. This partnership addresses all three points and allows a midsized enterprise to act like a large company and enterprises to act like hyperscalers. They get the security of an isolated environment and the performance of bare-metal GPUs, all managed through a unified Kubernetes stack. Final thoughts. The AI race is going to be won by the companies that solve the operational headaches of GPU management. The technology is there, but can organizations deploy it in a way where it meets their needs now, doesn't break the bank and can scale with them? The partnership between QumulusAI and vCluster lowers the barrier to entry for secure, high-performance environments and makes it possible for AI teams to move as fast as their ideas. And in today's market, speed isn't just an advantage - it's the only thing that matters. Zeus Kerravala is a principal analyst at ZK Research, a division of Kerravala Consulting.

vCluster Labs introduces Infrastructure Tenancy Platform for AI to maximize NVIDIA GPU efficiency on Kubernetes environments. New platform provides a Kubernetes-native foundation for running AI workloads on NVIDIA AI infrastructure, combining advanced isolation, dynamic scaling, and hybrid networking. ATLANTA (KubeCon + CloudNativeCon North America 2025, Booth #421) - November 10, 2025 - vCluster Labs, the company pioneering Kubernetes virtualization, today announced its Infrastructure Tenancy Platform for AI to help organizations build and operate high-performance AI infrastructure on GPU-focused compute clusters, including support for NVIDIA DGX systems. The company's new Reference Architecture for NVIDIA DGX systems is now available, offering architectural guidance for building secure, scalable Kubernetes environments optimized for NVIDIA AI infrastructure. Alongside this, vCluster introduced several new technologies, including vCluster Private Nodes, vCluster VPN, the Karpenter-based vCluster Auto Nodes feature, and direct integrations with NVIDIA Base Command Manager, KubeVirt, and the network isolation controller Netris, all of which form the foundation of the vCluster Infrastructure Tenancy Platform for AI, a unified framework for deploying and managing AI workloads on AI supercomputers in the private cloud as well as on top of hyperscalers and emerging neoclouds. "Our mission is to make AI infrastructure as dynamic and efficient as the workloads it supports," said Lukas Gentele, CEO of vCluster. "With our Infrastructure Tenancy Platform for AI, organizations running NVIDIA AI infrastructure can operate secure, elastic Kubernetes environments anywhere, with the performance, control, and efficiency that AI-scale workloads demand. It feels like getting the most cutting edge public cloud managed Kubernetes but on your bare metal AI supercomputer." Building blocks for the AI infrastructure era. As enterprises race to operationalize AI at scale, platform teams need a Kubernetes foundation that can manage GPU resources efficiently while ensuring workload isolation, mobility, and security. The Infrastructure Tenancy Platform for AI addresses these challenges through the following key innovations: * vCluster Private Nodes & Auto Nodes - Enable virtual clusters to dynamically autoscale GPU and CPU capacity across clouds, data centers, and bare metal environments using Karpenter-based automation. These features help maximize GPU utilization while maintaining full isolation and flexibility. * vCluster VPN - A Tailscale-powered overlay network that establishes secure communication between control planes and worker nodes across hybrid infrastructure. vCluster VPN simplifies burst-to-cloud scenarios, where GPU clusters seamlessly extend from on-premises NVIDIA DGX systems to public cloud environments. * NVIDIA Base Command Manager Integration - Integrates vCluster with NVIDIA Base Command Manager to bring Auto Nodes to NVIDIA DGX clusters, enabling elasticity, GPU lifecycle management, and efficient scaling across on-prem NVIDIA infrastructure. * KubeVirt Integration - Enables the creation of virtual machines on demand as nodes within a virtual cluster using KubeVirt, allowing large bare-metal servers to be partitioned into smaller, isolated compute units. This extends Auto Nodes to on-prem and bare-metal environments, giving platform teams elastic, tenant-aware GPU infrastructure under Kubernetes. * Netris Integration - Provides automated network isolation and lifecycle management for virtual clusters, giving each tenant its own dedicated network path and enabling multi-tenant GPU environments to run securely on shared infrastructure. * vNode Runtime - A secure, Kubernetes-native container sandbox that helps prevent container break-outs, enabling multi-tenant GPU workloads without reverting to VMs. Together, these technologies create the foundation of the vCluster Infrastructure Tenancy Platform for AI - a composable, Kubernetes-native framework purpose-built for running AI, ML, and GPU-intensive workloads anywhere. Industry analysts are increasingly highlighting the urgency of optimizing GPU utilization and simplifying AI infrastructure management. "As AI infrastructure becomes the new competitive frontier, organizations are under immense pressure to operationalize GPUs efficiently while maintaining security and governance across hybrid environments," stated Paul Nashawaty, Practice Lead and Principal Analyst at theCUBE Research. "We find that 71% of enterprises cite GPU utilization inefficiency as a major barrier to scaling AI workloads, and nearly two-thirds are exploring Kubernetes-native approaches to unify AI operations across cloud and on-prem. vCluster Labs' Infrastructure Tenancy Platform for AI directly addresses this gap by enabling dynamic, multi-tenant GPU orchestration with the same elasticity and control enterprises expect from the public cloud, now extended to private NVIDIA-powered AI systems." The new vCluster Reference Architecture for NVIDIA DGX systems outlines best practices for deploying virtual clusters on gpu-centric systems, enabling enterprises to deliver a cloud-like Kubernetes experience on-premises. With vCluster, teams can create lightweight virtual clusters that autoscale GPU resources, integrate securely with both on-prem and cloud networks, and maintain consistent performance across environments. "We've been using vCluster for a while and we love the technology," said Nick Jones, VP of Engineering at Nscale. "We're using vCluster to optimise GPU utilisation and accelerate Kubernetes cluster provisioning - delivering higher performance and efficiency that directly benefit our customers." Enabling cloud agility for NVIDIA GPU infrastructure. From AI factories to private GPU clouds, vCluster brings the scalability and efficiency of public cloud Kubernetes to NVIDIA environments. * Faster cluster provisioning - virtual clusters spin up in seconds with fully declarative provisioning via Terraform and GitOps * Higher GPU utilization - fewer idle GPUs across teams and tenants while ensuring fair use for everyone across the organization * Simplified day 2 operations - automated control plane and node upgrades, automatic backups with vCluster Snapshots and standardized guidance for integration into common cloud-native observability stacks Experience vCluster at KubeCon North America.

vCluster and Netris partner to bring cloud-grade Kubernetes to AI Factories & GPU Clouds with strong network isolation requirements. vCluster's virtual cluster technology and Netris's network automation enables AI operators to launch secure, multi-tenant Kubernetes environments faster - maximizing GPU utilization and scaling seamlessly across cloud, private data centers, and the edge. SAN FRANCISCO - October 28, 2025 - vCluster Labs (formerly LoftLabs), the company pioneering Kubernetes virtualization, today announced a strategic partnership with Netris, the leading NVIDIA-validated Network Automation and Multi-Tenancy Platform trusted by leading GPU cloud operators. As enterprises race to build and scale GPU-powered AI infrastructure, they increasingly face the challenge of running Kubernetes clusters outside of public clouds without losing agility. This partnership combines vCluster's lightweight, isolated virtual clusters with Netris's network automation and multi-tenancy, giving organizations the flexibility to run GPU and AI workloads anywhere, with the same speed, security, and simplicity they expect from the cloud. The two solutions address multi-tenancy at different layers: vCluster at the Kubernetes/compute layer and Netris at the network/abstraction layer, creating a complete foundation for secure, multi-tenant AI infrastructure. Now, through a native integration between vCluster and Netris, this multi-layer isolation becomes fully automated and effortless to operate. When new virtual clusters are created, vCluster can seamlessly connect to Netris networks, ensuring each tenant's Kubernetes environment has its own isolated data plane and network path. This enables operators to deliver cloud-grade security and automation on shared GPU infrastructure. "Our mission has always been to make Kubernetes tenancy simple, efficient, and secure," said Lukas Gentele, CEO and Co-Founder of vCluster. "With Netris, we extend that simplicity with built-in automation and hard multi-tenancy to the networking layer. vCluster ensures isolation at the Kubernetes and compute level, while Netris enforces it at the network and abstraction layer. Together, that's a full-stack approach to multi-tenancy for AI operators. This is especially critical for teams building GPU-based AI factories where strict tenant isolation is a hard requirement." Cloud-Grade Kubernetes for AI infrastructure. Traditionally, running Kubernetes outside the cloud has meant trade-offs. Developers lacked on-demand clusters, while operators had to manually configure load balancers, VPNs, and ACLs. Businesses faced costly sprawl and slowed delivery cycles. Issues are magnified in GPU and AI infrastructure, where utilization and performance directly impact economics. With the vCluster's new Netris integration, organizations can now: * Launch GPU-ready virtual clusters on demand with networking, load balancers, ingress, ACLs, and network isolation automatically configured by Netris through the vCluster integration. * Maximize utilization by securely running multiple tenants on shared clusters, with vCluster providing Kubernetes-level isolation and Netris providing network-level isolation. * Scale AI workloads to the edge with lightweight clusters seamlessly meshed back to central data centers via Netris's secure Site Mesh. Under the hood, the integration allows vCluster environments to attach directly to dedicated Netris networks, giving each tenant its own isolated data plane and Layer 2 connectivity. This eliminates manual Day-2 network configuration and simplifies ongoing operations for shared GPU infrastructure. Future enhancements will extend this integration to automate network creation during cluster provisioning, delivering full end-to-end lifecycle automation. The result: a developer-friendly, operations-ready Kubernetes platform that supports GPU workloads consistently across environments, from public cloud to bare-metal infrastructure to edge sites. Enabling cloud agility, anywhere AI runs. "Netris helps AI operators run like hyperscalers with automation, abstraction, and true multi-tenancy from day one," said Alex Saroyan, CEO and Co-Founder of Netris. "Partnering with vCluster delivers cloud-grade automation and multi-tenancy for Kubernetes, giving AI operators the foundation to run securely, onboard tenants instantly, and monetize GPUs faster." This partnership reflects a broader industry trend where enterprises seek the flexibility of the cloud for AI but increasingly need to run GPU workloads outside of hyperscalers due to cost, control, and performance requirements. With vCluster and Netris, they can finally achieve both.
