Red Hat OpenShift Container Platform capabilities
OpenShift Kubernetes engine
Red Hat OpenShift Kubernetes Engine delivers the foundational, security-focused capabilities of enterprise Kubernetes on Red Hat Enterprise Linux CoreOS to run containers in hybrid cloud environments. OpenShift Kubernetes Engine and OpenShift Container Platform are built on the same enterprise Kubernetes core platform and contain key Linux, container runtime, networking, management, and security capabilities. OpenShift Kubernetes Engine is ideal for those who prefer to use their existing infrastructure and developer tool investments.
Enterprise Kubernetes
Red Hat OpenShift delivers a modern, scalable approach to securing the entire application platform stack, from the operating system to containers to applications running in containers.
kubectl and OpenShift command-line interface (CLI)
Use kubectl, the native Kubernetes command-line interface (CLI) or the OpenShift CLI, to build, deploy, and manage applications–or even OpenShift Cluster itself.
Administrator web console
Use the browser-based web console to administer, visualize, browse, and manage OpenShift resources.
Red Hat OpenShift Virtualization
Red Hat OpenShift Virtualization lets you run and manage virtual machine workloads alongside container workloads. OpenShift Virtualization combines two technologies into a single management platform. This way, organizations can take advantage of the simplicity and speed of containers and Kubernetes, while still benefiting from the applications and services that have been architected for virtual machines.

Operator Lifecycle Manager (OLM)
Operator Lifecycle Manager (OLM) is a part of Operator Framework, an open source toolkit designed to manage Operators in an effective, automated, and scalable way. OLM helps developers install, update, and manage the lifecycle of Kubernetes native applications (Operators) and associated services running across their OpenShift Container Platform clusters.
Kubernetes cluster services
A key component of the OpenShift Kubernetes Engine is the core cluster services that automate the container application environment installations, upgrades, and life-cycle management without downtime.
Installing and Updating Clusters
OpenShift Installer is a simple, flexible, and matured command-line tool that helps with OpenShift cluster deployment on any infrastructure of your choice. OpenShift also comes with OpenShift Update Service, which provides over-the-air updates to the OpenShift platform, including Red Hat Enterprise Linux CoreOS. With the OpenShift platform, administrators can perform cluster updates with a single operation either via the web console or the OpenShift CLI and are notified when an update is available or completed.
Monitoring
OpenShift Container Platform includes a preinstalled, preconfigured, and self-updating monitoring stack that provides monitoring for core platform components. Several pre-built monitoring dashboards and sets of alerts notify cluster administrators about cluster health and help to quickly troubleshoot the issues. From the OpenShift web console, admins can view and manage metrics, and alerts for the cluster and can enable monitoring for user-defined projects.
Networking
OpenShift offers full, supported access to the Kubernetes Container Network Interface (CNI), including support for any third-party software-defined networking solution that is compatible with the Red Hat OpenShift Container Platform. OpenShift includes Open vSwitch software-defined networking (SDN) and also allows you to take full advantage of the Open Virtual Network (OVN) Kubernetes overlay, Multus, and Multus plugins that are supported on OpenShift.
Storage
OpenShift Container Platform supports multiple types of storage, both for on-premise and cloud providers. You can manage container storage for persistent and non-persistent data in an OpenShift Container Platform cluster. OpenShift Container Platform uses the Kubernetes persistent volume (PV) framework to allow cluster administrators to provision persistent storage for a cluster. Developers can use persistent volume claims (PVCs) to request PV resources without having specific knowledge of the underlying storage infrastructure.
Container Registry
As a part of cluster services, OpenShift provides a built-in container image registry, an out-of-the-box solution for developers to store and manage container images that run their workloads. This internal registry can be scaled up or down like any other cluster workload without infrastructure provisioning. OpenShift registry is also integrated into the cluster's authentication and authorization system, enabling developers to have fine-grained control over container images.

Authentication and Authorization
OpenShift comes pre-build with central authentication and authorization services. The authentication layer identifies the user associated with requests to the OpenShift Container Platform API while the authorization layer then uses information about the requesting user to determine if the request is allowed. Administrators can define permissions and assign them to users using the RBAC objects, roles, and bindings. And can control access to thought projects, namespaces, and Security Context Constraints (SCCs).
App Management using Helm
Operators are among the most important components of the OpenShift Container Platform. Operators are the preferred method of packaging, deploying, and managing services on OpenShift. As a developer, you can install operator SDK CLI to create Go, Ansible, or Helm-based operators. The OpenShift web console can be used to select and install a chart from the Helm charts listed in the Developer Catalog, as well as add custom Helm chart repositories. The Helm CLI is integrated with the OpenShift web terminal making it easy to visualize, browse, and manage information regarding projects.
