What's OpenShift?



OpenShift is a platform as a service product from Red Hat.

OpenShift is Red Hat’s public cloud application development and hosting

platform that automates the provisioning, management and scaling of applications

so that you can focus on writing the code for your business, startup, or big idea.

OpenShift Architectures

OpenShift v2 / OpenShift v3



Applications

- In OpenShift v2, an application was a single unit - it consisted of one web framework

and no more than one of any given cartridge type.

- Linking was limited to within an application and only worked within cartridges

designed to work together.

- In OpenShift v3 remove "application" as a keyword since "application" can mean

something different to everyone.

- Flexible linking: means you can link any two arbitrary components together.



Cartridges vs Images

● Dependencies

● Collocation

● Source Code

● Build

● Routing



Terminology

● Application

● Gear vs Container

● Cartridge vs Image

● Domain vs Project

● Broker vs Master
