Red Hat Updates OpenShift and Red Hat Advanced Cluster Management for Kubernetes to Push the Edge Further

Red Hat Inc., the world's leading provider of open source solutions, today announced Red Hat OpenShift 4.9 and Red Hat Advanced Cluster Management for Kubernetes 2.4, both designed to extend the open hybrid cloud's consistency to the enterprise network's most remote locations. The new capabilities, which include the general availability of a single node OpenShift for a small, full-featured enterprise Kubernetes cluster, assist organisations in scaling existing development, deployment, and management workflows to meet increased demand for information and services.

According to IDC, 50% of new enterprise IT infrastructure deployed will be at edge sites rather than in corporate data centres, up from less than 10% in 2021. By 2024, IDC predicts an 800% increase in the number of applications deployed in edge sites. Organisations across industries are using edge computing to deploy latency sensitive applications to deliver the best application experience to users and make faster data-driven decisions to benefit their business.

With an increased demand for applications to run in remote locations, organisations require tools that allow them to deploy at the edge more easily and manage those applications at scale. The most recent updates to Red Hat OpenShift 4.9 and Red Hat Advanced Cluster Management 2.4 give organisations the flexibility and management capabilities they need to deploy workloads wherever it makes sense.
 
Full Kubernetes capabilities for the small deployment footprint
As organisations embrace edge computing, the physical nature of edge sites can present challenges for architects who must deploy hardware in confined spaces or where network connectivity may be intermittent. The industry’s leading enterprise Kubernetes platform, Red Hat OpenShift 4.9, can now provide users with a more consistent experience across all of their sites, regardless of the size of the deployment.

Red Hat OpenShift 4.9 introduces single node OpenShift, the 3rd topology option available for edge sites alongside 3-node clusters and remote worker nodes. Single node OpenShift puts both control and worker capabilities into a single server to help fit into space-constrained environments. Additionally, single node OpenShift provides operational independence for edge sites as there is no dependency on a centralised Kubernetes control plane - making it far easier for edge sites that may experience lapses in connectivity, like remote cell towers or manufacturing facilities.
 
Manage Red Hat OpenShift everywhere, from bare metal to the edge
Edge deployments can range from hundreds to hundreds of thousands of Kubernetes clusters, and they frequently require management in locations with little to no IT personnel. Red Hat Advanced Cluster Management provides a single, consistent view from edge locations to data centres and cloud environments, allowing organisations to more consistently manage across sites and clusters without requiring a permanent connection between Red Hat Advanced Cluster Management and the edge site.

The latest Red Hat Advanced Cluster Management version provides full management capabilities for an organisation’s entire application landscape, including across single node OpenShift, remote worker nodes, and 3-node clusters. This helps to ease the operational strain of managing a scaled out architecture.

Additional edge-focused capabilities include:

  • Edge management at scale, provides users the ability to manage close to 2,000 single node Openshift clusters by a single Red Hat Advanced Cluster Management hub (available as a technology preview) along with IPv6 dual stack support for the managed fleet. This helps deliver scalability in low bandwidth, high-latency connections and disconnected sites.

  • Hub-side policy templating which reduces the number of policies needed for high scale management scenarios by reading a single policy on the hub and applying it to varied cluster scenarios.

  • Zero touch provisioning, available as a technology preview, enables users to use an assisted installer with Red Hat Advanced Cluster Management on-premises, simplifying the starting complexities of high scale cluster deployments.

Simplified, reproducible complete edge stacks
Most edge deployments today are complex to design and implement, and require multiple products to work together. To help simplify the process of building a complete edge stack, Red Hat is introducing Red Hat validated patterns.

Red Hat validated patterns for edge bring together the necessary components to architect an edge stack, helping to reduce complexity and save time. Delivering “edge stacks as code,” Red Hat validated patterns defines, builds and validates the software configurations needed for edge deployments. As new software versions are introduced, the templates are re-validated to work as designed, minimising the risk to customers and enabling them to take advantage of any new capabilities that are introduced. Additionally, the validated patterns are open, enabling contributors to collaborate and suggest improvements.
