The recipe for stateful Kubernetes application restoration
Ramen is a cluster-management (OCM) extension that offers recovery and relocation services for workloads and their persistent data. Ramen provides cloud-native interfaces to manage the actions during capture or restore workflow that are called Recipes.
The recipes have detailed steps needed for an application to function successfully once the backup or restoration is complete. We will focus on how some imperative applications can be restored using this feature. With Ramen and recipe users can optimize resource usage by effortlessly moving workloads between clusters while minimizing downtime during relocation. We invite the community to contribute to the recipe repository to increase the scope and versatility of Ramen's functionality by sharing their workflow scripts for Capture or Recover actions.
Resilient On-Premise Infrastructure for Running Kubernetes Clusters: Strategies and Best Practices
We will explore strategies for building a resilient on-premise infrastructure for running OpenShift clusters using hyperconverged infrastructure. We will cover key components, such as networking, storage, and compute resources, and also strategies for protecting applications running on the platform using backup-restore and disaster recovery plans.

Complementing this, HyperShift emerges as a middleware solution for hosting OpenShift control planes at scale.
The practical journey unfolds with detailed insights into setting up and running such infrastructure. Learn the step-by-step process of deploying fault-tolerant Kubernetes clusters on bare metal, emphasizing the integration of KubeVirt and HyperShift. Join us for an immersive guide that not only navigates the nuances of orchestration but also equips participants with the practical skills needed to implement and manage resilient AI infrastructure.
Ensuring Highly Resilient Red Hat Hosted Control Plane Deployments in Appliance Form Factor
RedHat addresses the complexity of managing multiple clusters with Hosted Control Planes (HCP), based on the Hypershift project. HCP, available on VMs, cloud, or as an appliance—reduces the operational burden of control plane infrastructure management. This session delves into deploying a resilient HCP in an appliance form factor, preventing complete solution downtime due to component failures. Key considerations include addressing physical node, network, storage, and complete appliance failures. Resiliency is achieved by replicating HCP and its control plane across multiple nodes, employing high-speed disk replication for critical components like etcd, and implementing backup strategies. Disaster recovery capabilities of the underlying appliance, such as metro and regional DR, are harnessed to minimize control plane downtime. Attendees will gain insights into configuring a highly resilient HCP deployment, utilizing Backup & Restore and DR technologies for nearly zero downtime.
