Introduction to OpenShift

OpenShift is a Platform as a Service (PaaS) that simplifies application development by providing pre-configured language runtimes, data stores, and administrative tools, allowing developers to focus on coding without worrying about the underlying infrastructure.
OpenShift v3 leverages Docker for containerization and Kubernetes for orchestration, enhancing the scalability, reliability, and manageability of containerized applications.
Linux containers, which are fundamental to Docker and Kubernetes, offer significant advantages over traditional virtualization by sharing the host operating system kernel and providing isolation through kernel namespaces and control groups (cgroups).
Kubernetes serves as a cluster manager and orchestrator, ensuring desired states of deployments, managing resources, and providing software-defined networking and storage to containers.
OpenShift adds value on top of Kubernetes by offering robust build and deployment systems, easy-to-use UI, logical project divisions, and integration with continuous integration/continuous delivery (CI/CD) pipelines for automated and efficient application development and deployment.
