With the Red Hat OCP solution, we have created the stable and reliable infrastructure necessary for Microservices transformation. We implemented the end-to-end CI/CD pipeline with the power of GitLab technology. By combining our efforts to containerize applications with the flexibility of Helm technology, we started to make them Kubernetes-ready.
Red Hat OpenShift Platform offers end-to-end secure and manageable "Platform as a Service" infrastructure. Thanks to the support of the Operator Hub, the application lifecycle can be managed much more quickly. More than 1,000 mission and business-critical applications can run as microservices. Automation of CI/CD processes has been achieved. In this way, much higher quality and faster developments can be made. End-to-end updating of existing Red Hat OCP clusters can be done quickly and easily.
