OpenSource For You - - INSIGHT -

To be­come familiar with OpenShift, you need to un­der­stand the ter­mi­nol­ogy as­so­ci­ated with it. Let’s look at a few im­por­tant terms as­so­ci­ated with OpenShift.

Gears: The server con­tain­ers along with their as­so­ci­ated re­sources are called gears. They en­able you to run your ap­pli­ca­tions. There are three types of gears, as listed be­low: • Small gears, which have 512MB of RAM • Medium gears have 1GB of RAM • Large gears have 2GB of RAM The disk space pro­vided with all th­ese gears is 1GB in the de­fault mode.

Car­tridges: To make the gears us­able for spe­cific pur­poses, OpenShift re­quires you to add the com­po­nents. Th­ese plug­gable en­ti­ties are known as car­tridges. Each gear can have a num­ber of car­tridges. At the same time, a sin­gle car­tridge can run on more than one gear. Car­tridges are of two types as shown in Fig­ure 3.
