Nutanix has recently announced the introduction of NKP Metal, extending the Nutanix operating model and Nutanix Kubernetes Platform (NKP) solution to support Kubernetes deployments directly on bare-metal infrastructure.
Why organizations deploying Kubernetes workloads require unique performance capabilities
According to Nutanix, running Kubernetes on bare metal delivers performance and flexibility that many modern workloads require, particularly for edge environments and AI training workloads that rely on dense GPU infrastructure.
However, operating these environments at scale introduces complexities in provisioning, integration, and management, leading many organizations to build highly specialized, siloed teams to manage bare-metal Kubernetes deployments.
NKP’s dual-native architecture and Kubernetes virtualization
To address challenges like these, NKP supports a dual-native architecture where containers and virtual machines operate as first-class infrastructure under a unified operating model, including for AI and other workloads that often run directly on bare-metal infrastructure.
“NKP Metal now offers the same security and networking support for Kubernetes running in bare metal that we have in Kubernetes running on VMs. In addition, we’ve got the same data services, snapshops, replication, and DR run in a bare metal environment with our container NKP Platform as they do in an NKP platform running in virtual machines,” said Lee Caswell, Senior Vice President of Product and Solutions Marketing, Nutanix.
“This really gives us an interesting opportunity to give customers the full choice of running Kubernetes either in virtual environments or on bare metal.”
Caswell said Nutanix expects that “in the data center itself, in the virtual private data center, running Kubernetes on virtualization is the preferred method because you marry up the benefits of agile software development with the benefits of virtualization.”
Nutanix expands its operating model as Kubernetes gains popularity
NKP Metal extends the Nutanix operating model and HCI stack to bare-metal Kubernetes environments, enabling organizations to run containers directly on physical infrastructure while maintaining a consistent level of automation, lifecycle management, networking, and enterprise data services found in virtualized environments.
“Running Kubernetes on bare metal has traditionally meant sacrificing the operational simplicity of virtualized environments,” said San Ciruli, Vice President and General Manager, Cloud Native, Nutanix.
“With NKP Metal, we’re extending the Nutanix operating model to bare-metal Kubernetes, combining automated lifecycle management with integrated Cloud Native AOS data services to deliver the simplicity, consistency, and enterprise storage capabilities customers need on their physical infrastructure.”
Consumption models include container storage or Cloud Native AOS
Customers can now choose to consume Nutanix storage through a container storage interface or use Cloud Native AOS as a purpose-built storage option for true bare-metal Kubernetes deployments while leveraging Nutanix Data Services for Kubernetes-native data services.
This will extend the Nutanix experience end-to-end while keeping storage closer to Kubernetes workloads.
Further, NKP Metal enables organizations to deploy and manage containerized workloads on physical servers while maintaining the operational simplicity, automation, and enterprise services of the Nutanix Cloud Platform solution.
The solution will simplify the lifecycle management of physical infrastructure while leveraging capabilities such as automated node deployment with Nutanix Foundation and OS and Firmware lifecycle management through Lifecycle Manager.
This gives organizations the ability to provision, scale, patch, and update bare-metal Kubernetes environments while retaining the operational consistency of virtualized workloads.
