Upgrade Strategies for Your Rafay MKS Cluster

In the past, there was only one way to upgrade your Rafay provisioned upstream Kubernetes cluster. The worker nodes were upgrade sequentially one worker node at a time. For large clusters with 100s of worker nodes, upgrades can take a very long time. In this blog, we will describe optimizations we have incorporated in our August 2023 release to allow users to configure faster upgrades. We now offer two ways to upgrade, and you have the freedom to choose the one that suits you best.

AWS Cross Account Support for EKS LCM in Rafay

Our recent release update in July to our Preview environment adds support for a number of new features and enhancements. This blog is focused on Cross Account Role ARN Support for Amazon EKS.

In July 2023, Rafay introduced a new feature to its Kubernetes Operations Platform: Cross Account Role ARN support for Amazon Elastic Kubernetes Service (EKS). This feature is designed to cater organizations that operate multiple AWS accounts, providing a seamless and efficient way to manage EKS clusters across these accounts. In this blog post, we'll delve into the significance of this enhancement, explore its use cases, and understand how it simplifies EKS cluster management across multiple AWS accounts.

Understanding Component Upgrades in an Upstream Rafay MKS Cluster

Upgrading a Kubernetes cluster is a crucial process that ensures your infrastructure stays up-to-date with the latest features, bug fixes, and security patches. As part of this process, several components within the cluster undergo upgrades.

In this blog post, we will explore the components that typically get upgraded during a cluster upgrade and highlight some of the periodic upgrades that both Cloud Service Providers (CSPs) and Rafay undertakes to enhance cluster performance and stability.
