Openshift 'overview'
Introduction¶
Red Hat OpenShift Container Platform (OpenShift) is a container application platform that provides developers and IT organizations with a cloud application platform for deploying new applications on secure, scalable resources with minimal configuration and management overhead.
Built on Red Hat Enterprise Linux, Docker, and Kubernetes, OpenShift provides a secure and scalable multitenant operating system for today’s enterprise applications, while providing integrated application runtimes and libraries. OpenShift brings a robust, flexible, and scalable container platform to customer data centers, enabling organizations to implement a platform that meets security, privacy, compliance, and governance requirements.
Applications run as containers, which are isolated partitions inside a single operating system. Containers provide many of the same benefits as virtual machines, such as security, storage, and network isolation, while requiring far fewer hardware resources and being quicker to launch and terminate. The use of containers by OpenShift helps with the efficiency, elasticity, and portability of the platform itself as well as its hosted applications.

What is OpenShift?¶
Red Hat OpenShift¶
With Red Hat OpenShift, OpenShift developers have a fast and secure way to containerize and deploy enterprise workloads in Kubernetes clusters. OpenShift clusters build on Kubernetes container orchestration that offers consistency and flexibility in operations. Because IBM manages OpenShift Container Platform (OCP), you'll have more time to focus on your core tasks.
Features¶
OpenShift experience built on Kubernetes Use the OpenShift tools and APIs you already know for a single, consistent experience, even when working across hybrid environments or different cloud providers.
Heightened cluster and app security IBM provides security features to protect your cluster infrastructure, isolate your compute resources, encrypt data, and ensure security compliance in your container deployments. Further, OpenShift sets up strict Security Context Constraints for greater pod security by default.
Worldwide, continuous availability Deploy and scale workloads across the globe in all IBM Cloud multizone regions. OpenShift clusters include a managed master that is automatically spread across zones within the region for high availability.
Integrated OpenShift catalog Quickly set up a CI/CD with Jenkins or deploy a variety of apps in a guided experience that's fully integrated into your OpenShift cluster.
