Part 2: Considerations: Understand the key considerations before Configuring EKS Auto Mode.
In this post, we will dive into the steps required to build and manage an Amazon EKS cluster with Auto Mode template using the Rafay Platform. This exercise is specifically well suited for platform teams interested in providing their end users with a controlled self-service experience with centralized governance.
In continuation of our Part 1 intro blog on the Kube-OVN CNI, this is Part 2, where we will cover how easy it is to manage CNI configurations using Rafay's Blueprint Add-On approach.In the evolving cloud-native landscape, networking requirements are becoming more complex, with platform teams needing enhanced control and customization over their Kubernetes clusters. Rafay's support for custom, compatible CNIs allows organizations to select and deploy advanced networking solutions tailored to their needs. While there are several options available, this blog will focus specifically on deploying the Kube-OVN CNI. Using Rafay’s Blueprint Add-On approach, we will guide you through the steps to seamlessly integrate Kube-OVN into an upstream Kubernetes cluster managed by Rafay’s Managed Kubernetes Service.
Our upcoming release, scheduled for December in the production environment, introduces several new features and enhancements. Each of these will be covered in separate blog posts. This particular blog focuses on the support and process for deploying Kube-OVN as the primary CNI on an upstream Kubernetes cluster.
Watch a video showcasing how users can customize and configure Kube-OVN as the primary CNI on Rafay MKS Kubernetes clusters.
Kubernetes has become the de facto standard for orchestrating containerized applications, but efficient networking remains one of the biggest challenges. For Kubernetes networking, Container Network Interface (CNI) plugins handle the essential task of managing the network configuration between pods, nodes, and external systems. Among these CNI plugins, Kube-OVN stands out as a feature-rich and enterprise-ready solution, designed for cloud-native applications requiring robust networking features.
In this blog, we will discuss how it is different from popular CNI plugins such as Calico and Cilium and use cases where it is particularly useful.
Platform teams today are increasingly tasked with balancing cost efficiency, compliance, and operational agility across complex cloud environments. Actions such as cost-optimization measures and compliance-related tasks are critical, yet executing these tasks consistently and effectively can be challenging.
With the recent introduction of the “Schedules” capability on the Rafay Platform, platform teams can now orchestrate one-time or recurring actions across environments in a standardized, centralized manner. This new feature enables teams to implement cost-saving policies, manage compliance actions, and ensure operational efficiency—all from a single interface. Here’s a closer look at how this feature can streamline your workflows and add value to your platform operations.
In the prior blogs, we discussed why GPUs are managed differently in Kubernetes, how the GPU Operator helps streamline management and various strategies to share GPUs on Kubernetes. In 2020, Nvidia introduced Multi-Instance GPU (MIG) that takes GPU sharing to a different level.
In this blog, we will start by reviewing some common industry use cases where MIG is used and then dive deeper into how MIG is configured and used.
In the previous blogs, we discussed why GPUs are managed differently in Kubernetes and how the GPU Operator can help streamline management. In Kubernetes, although you can request fractional CPU units for workloads, you cannot request fractional GPU units.
Pod manifests must request GPU resources in integers which results in an entire physical GPU allocated to one container even if the container only requires a fraction of the resources. In this blog, we will describe two popular and commonly used strategies to share a GPU on Kubernetes.
This is a follow up from the previous blog where we discussed device plugins for GPUs in Kubernetes. We reviewed why the Nvidia device plugin was necessary for GPU support in Kubernetes. A GPU Operator is needed in Kubernetes to automate and simplify the management of GPUs for workloads running on Kubernetes.
In this blog, we will look at how a GPU operator helps automate and streamline operations through the lens of a market leading implementation by Nvidia.
Unlike CPU and Memory, GPUs are not natively supported in Kubernetes. Kubernetes manages CPU and memory natively. This means it can automatically schedule containers based on these resources, allocates them to Pods, and handles resource isolation and over-subscription.
GPUs are considered specialized hardware and require the use of device plugins to support GPUs in Kubernetes. Device Plugins help make Kubernetes GPU-aware allowing it to Discover, Allocate and Schedule GPUs for containerized workloads. Without a device plugin, Kubernetes is unaware of the GPUs available on the nodes and cannot assign them to Pods. In this blog, we will discuss why GPUs are not natively supported and understand how device plugins help address this gap.
Maintaining stringent security and compliance standards is more critical than ever today. Implementing break glass workflows for developers presents unique challenges that require careful consideration to prevent unauthorized access and ensure regulatory compliance.
In the previous blog, we introduced the concept of break glass workflows and why organizations require it. This blog post delves into how Rafay enables Platform teams to orchestrate secure and compliant break glass workflows within their organizations. Watch a video recording of this feature in Rafay.
In the previous blog, we introduced the concept of custom schedulers and why they are necessary for certain use cases. In this blog, we will compare and contrast three popular schedulers: Volcano, Kueue and Yunikorn.
