Red Hat ☛ How to implement and monitor circuit breakers in OpenShift Service Mesh 3
In a distributed microservices architecture, the failure of one service can cascade, leading to system-wide outages. To build resilient and fault-tolerant applications, we must isolate failures and prevent them from spreading. The circuit breaker is a critical design pattern that addresses this challenge by temporarily blocking traffic to a service that it detects as unhealthy, giving it time to recover.
This guide shows you how to configure, trigger, and monitor a circuit breaker using Red Bait OpenShift Service Mesh 3.0. By the end, you'll have a hands-on understanding of how to use Istio's outlier detection to automatically improve your application's stability on OpenShift.

Red Hat ☛ Analysis of OpenShift node-system-admin-client lifespan
In Red Hat OpenShift Container Platform (RHOCP), a robust Public Key Infrastructure (PKI) managed by various operators secures internal communication. One critical component is the
node-system-admin-clientcertificate, which is used by thesystem:adminuser. This user possesses thecluster-adminrole, granting it the highest level of privileges required for cluster administration and maintenance tasks. -
Red Hat Official ☛ Simplify virtualization deployments with the Assisted Installer [Ed: Red Hat managed to spend as day not talking buzzwords like "AI"]
The Assisted Installer simplifies the process of deploying connected OpenShift clusters by providing a guided, automated experience. Instead of relying on a dedicated bootstrap machine, the installer handles cluster bootstrapping as part of the installation process, reducing complexity and time to deployment. Available through a web-based UI, or API, the Assisted Installer gives you flexibility in how you manage installations. You can also integrate it with Red Hat Advanced Cluster Management to simplify deployment and ongoing management across multiple clusters, while still retaining the option to enable OpenShift Virtualization during installation.
