DO188 OpenShift Development I:Container with OpenShift & Kubernetes Deploy Applications in OpenShift

Objectives
Deploy an application in OpenShift.
Kubernetes and Red Hat OpenShift
Kubernetes is an orchestration platform that simplifies the deployment, management, and scaling of containerized applications. Kubernetes uses several servers, called nodes, to ensure the resiliency and scalability of the deployed applications. Kubernetes forms a cluster of servers that run containers and are centrally managed by a set of control plane servers. A server can act as both a control plane node and a compute node, but those roles are usually separated for increased stability, security, and manageability.
Red Hat OpenShift is a set of modular components and services that use and expand Kubernetes. Red Hat OpenShift adds capabilities such as remote management, increased security, monitoring and auditing, application lifecycle management, and self-service interfaces for developers.
Based on your infrastructure needs, you can choose from various Red Hat OpenShift editions. Red Hat OpenShift Container Platform (RHOCP) is one of the self-managed options, which you can install and configure on your own infrastructure. RHOCP supports many different target platforms, such as Amazon Web Services (AWS), Microsoft Azure, and bare metal.
Red Hat OpenShift is also available as a cloud managed service. A managed platform can reduce your operational effort and increase your productivity, because you do not need to maintain the infrastructure layer. Examples of Red Hat OpenShift managed services are Microsoft Azure Red Hat OpenShift (ARO) and Red Hat OpenShift Service on AWS (ROSA), among others.
