OpenShift came into existence from its base named OpenShift V2, which was mainly based on the concept of gear and cartridges, where each component has its specifications starting from machine creation till application deployment, right from building to deploying the application. 

Cartridges:  They were the focal point of building a new application starting from the type of application the environment requires to run them and all the dependencies satisfied in this section. 

Gear:  It can be defined as the bear metal machine or server with certain specifications regarding the resources, memory, and CPU. They were considered as a fundamental unit for running an application. 

Application:  These simply refer to the application or any integration application that will get deployed and run on OpenShift environment. 

As we go deeper in the section, we will discuss on different formats and offerings of OpenShift. In the earlier days, OpenShift had three major versions. 

OpenShift Origin:  This was the community addition or open source version of OpenShift. It was also known as upstream project for other two versions. 

OpenShift Online:  It is a pubic PaaS as a service hosted on AWS. 

OpenShift Enterprise:  This is the hardened version of OpenShift with ISV and vendor licenses.
