Amazon EKS Anywhere gains support for bare metal servers


Amazon Web Services Inc. today announced that Amazon EKS Anywhere now supports bare metal servers, meaning servers without an installed operating system or applications, meaning customers can simplify and standardize Kubernetes deployments on their self-managed bare metal infrastructure .

Launched in September, Amazon EKS Anywhere is an extension of the Amazon Elastic Kubernetes service that enables organizations to run Kubernetes on the enterprise infrastructure without the need for a control pane or nodes to be installed, operated, and maintained. Amazon EKS Anywhere takes this a step further, enabling customers to build and run Kubernetes clusters on virtualized on-premises servers using VMware Inc.’s vSphere.

Now they have another option to deploy Amazon EKS on bare metal servers, which are physical servers dedicated to a single tenant. This allows the performance and security of the server to be optimized specifically for a single workload.

Bare metal servers are an alternative to hypervisor servers, where multiple workloads share the hardware’s compute, storage, and other resources. According to Amazon, by bringing AKS Anywhere to bare-metal servers, customers have more options for how to manage and operate Kubernetes-based containers that host the components of modern applications.

In a blog post, Amazon cited a number of reasons customers are using bare metal: performance benefits, direct access to underlying hardware resources, reduced complexity in their infrastructure stack, and savings in licensing and support costs. And as they modernize their applications, they want to use Kubernetes consistently between their existing on-premises bare metal infrastructure and the cloud.

In general, running Kubernetes on a bare metal infrastructure is a complex and tedious task that requires specialized expertise and a significant investment of time. Although using a virtualization layer eliminates these problems, it increases the burden of software licensing and support costs.

On the other hand, according to AWS, EKS on bare metal allows customers to automate all the steps required to set up, from provisioning to operating, a Kubernetes cluster based on open-source tools. The company said its support includes all Amazon EKS Anywhere components, including third-party integrated software. This means customers can now take advantage of running Kubernetes on their own bare metal servers with no support and software license costs.

AWS said a number of customers deployed Amazon EKS on bare metal while the feature was in preview. These include Inc., a TV advertising measurement company that does a lot of computing power in the cloud. Taut Bruzas, Director of Information Technology Operations at, said he and his team have come to love Amazon EKS.

“It gives us the flexibility and performance we need, which is essential for us, and we couldn’t wait for Amazon’s EKS Anywhere as it would allow for consistency between our on-premises and cloud deployments,” he explained. “The ability to install/run EKS Anywhere on bare metal and have fully supported Kubernetes cloud orchestration is something we’ve been waiting for a long time.”
