Kubernetes Master Class: Single Node, Standalone Servers, and Scalable, Secure Storage

Not all of us have unlimited budgets for infinite nodes, and even if you do, it's important to spend wisely. If you're running Rancher in a non-production environment and want to start with a single node now and upgrade to an HA configuration later, you can do this with RKE. Once a cluster is up and running, make the best use of your available storage by deploying block-level replication with OpenEBS within your Kubernetes clusters.

Load balancing, traffic management, authentication and authorization, service discovery — these are just some of the interactions taking place between microservices. Collectively called a “service mesh”, these interconnections can become an operations headache when handling large‑scale, complex applications. Istio seeks to reduce this complexity by providing engineers with an easy way to manage a service mesh.

Simplify Migration from OpenShift 3 to 4

This is a guest post written by Appranix. Now that Red Hat OpenShift 4 has officially been released, it’s time to start thinking about migration from Red Hat OpenShift Container Platform 3 to OpenShift Container Platform 4. You can check out the details about the differences between OpenShift 3 and 4 here. One of the biggest differences between OpenShift 3 and 4 is how OpenShift 4 clusters operate using immutable and automated infrastructure enabled by RHEL CoreOS and automation.
