Weblogic Kubernetes operator or how to run WebLogic​ clusters in k8s


There are lots of WebLogic clusters running around the globe every day. When you withdraw money in the ATM, buy lettuces in the supermarket or make a phone call there is a WebLogic server (and probably an Oracle database too) is executing some logic for you.

Computing paradigms today tend to new standards and Kubernetes seems to be a big player for running workloads that need scalability, high availability, fault tolerant and resilience to disasters.

WebLogic was born in the 2000s with concepts such clusters, managed servers or nodemanager. Those entities were engineered for building robust software designed to run in the infrastructure utilized in the last years.

With the advent of the cloud, new paradigms and technologies arise, but things can’t be constantly rebuilt every time a new technology appears because of the cost of renewing it. The number of lines of  Java code written and compiled to run in WebLogic out there is huge, so is good for you to have the confidence that your current software will keep running and will allow you to modernize your applications progressively. The importance of having providers that guarantee the continuity of businesses goes beyond the technology trends or the latest fashioned cool software product launched yesterday.

For that reason, Oracle provides WebLogic-Kubernetes-Operator, a collection of artifacts that transparently translates the WebLogic architectural design concepts (AdminServer, managed server, NodeManager, …) to the Kunernetes concepts (pods, deployments, persistent volumes, replicasets,…) allowing to run WebLogic topologies in k8s transparently.

With WebLogic-Kubernetes-Operator, Oracle provides a way for keeping safe the investments you have done so far and gives you time to face the future with tranquility.

Enjoy 😉
