+
+Kubernetes is an open source container orchestration tool developed by Google. You can run and manage container-based workloads by using Kubernetes. The most common Kubernetes use case is to deploy an array of interconnected microservices, building an application in a cloud native way. You can create Kubernetes clusters that can span hosts across on-premise, public, private, or hybrid clouds.
+
+Traditionally, applications were deployed on top of a single operating system. With virtualization, you can split the physical host into several virtual hosts. Working on virtual instances on shared resources is not optimal for efficiency and scalability. Because a virtual machine (VM) consumes as many resources as a physical machine, providing resources to a VM such as CPU, RAM, and storage can be expensive. Also, you might see your application degrading in performance due to virtual instance usage on shared resources.

+.Evolution of container technologies for classical deployments

+
+To solve this problem, you can use containerization technologies that segregate applications in a containerized environment. Similar to a VM, a container has its own filesystem, vCPU, memory, process space, dependencies, and more. Containers are decoupled from the underlying infrastructure, and are portable across clouds and OS distributions. Containers are inherently much lighter than a fully-featured OS, and are lightweight isolated processes that run on the operating system kernel. VMs are slower to boot, and are an abstraction of physical hardware. VMs run on a single machine with the help of a hypervisor.
+
+You can perform the following actions by using Kubernetes:
+
+* Sharing resources
+* Orchestrating containers across multiple hosts
+* Installing new hardware configurations
+* Running health checks and self-healing applications
+* Scaling containerized applications

+.Architecture of Kubernetes
+image::247_OpenShift_Kubernetes_Overview-2.png[]
+
+A cluster is a single computational unit consisting of multiple nodes in a cloud environment. A Kubernetes cluster includes a control plane and worker nodes. You can run Kubernetes containers across various machines and environments. The control plane node controls and maintains the state of a cluster. You can run the Kubernetes application by using worker nodes. You can use the Kubernetes namespace to differentiate cluster resources in a cluster. Namespace scoping is applicable for resource objects, such as deployment, service, and pods. You cannot use namespace for cluster-wide resource objects such as storage class, nodes, and persistent volumes.

+
+Red Hat OpenShift is offered in several editions to support a wide range of deployment models and operational preferences. Each edition delivers a consistent Kubernetes platform with integrated tools, security features, and developer experiences. OpenShift is available in cloud services and self-managed editions.
+
+[id="cloud-services-editions_{context}]
+== Cloud services editions
+
+Red Hat OpenShift offers various cloud service editions to cater to different organizational needs. These editions provide fully managed application platforms from major cloud providers.
+
+{{product-rosa}} (ROSA):: A fully managed application platform that helps organizations build, deploy, and scale applications in a native AWS environment.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/aws[{{product-rosa}}].
+
+{{azure-first}} Red Hat OpenShift:: A fully managed application platform that helps organizations build, deploy, and scale applications on Azure.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/azure[{{azure-first}} Red Hat OpenShift].
+
+{{product-dedicated}}:: A managed Red Hat OpenShift offering available on Google Cloud Platform (GCP).
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/dedicated[{{product-dedicated}}].
+
+Red Hat OpenShift on {{ibm-cloud-title}}:: A managed OpenShift cloud service that reduces operational complexity and helps developers build and scale applications on {{ibm-cloud-title}}.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/ibm[Red Hat OpenShift on {{ibm-cloud-title}}].
+
+[id="self-managed-editions_{context}]
+== Self-managed editions
+
+Red Hat OpenShift offers self-managed editions for organizations that prefer to deploy, configure, and manage OpenShift on their own infrastructure. These editions provide flexibility and control over the platform while leveraging the capabilities of OpenShift.
+
+Red Hat {product-title} (OCP)::
+Provides complete set of operations and developer services and tools for building and scaling containerized applications.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/container-platform[Red Hat {product-title}].
+
+Red Hat {{opp}}::
+Builds on the capabilities of {product-title}.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/platform-plus[Red Hat {{opp}}].
+
+Red Hat {{oke}}::
+Delivers the foundational, security-focused capabilities of enterprise Kubernetes on {{op-system-first}} to run containers in hybrid cloud environments.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/kubernetes-engine[Red Hat {{oke}}].
+
+{{ove-first}}::
+Provides the virtualization capabilities of Red Hat OpenShift in a streamlined, cost-effective solution to deploy, manage, and scale VMs exclusively.
+For more information, see link:https://www.redhat.com/en/technologies/cloud-computing/openshift/virtualization-engine[{{ove-first}}].
