Title Instantly Run An App in the Cloud Using OpenShift
Overview Students need to know what Cloud Computing really means, how it fits into the wider computing context, and how they can use an open source cloud alternative to quickly host coding platforms for them to toy around in. This activity sets out to do all of this as a walkthrough learn-as-you-go tutorial.
Prerequisite Knowledge Command line skills and Beginner Git experience (git activity 1)
Learning Objectives
  • Understand what Cloud / Utility Computing is
  • Be able to quickly spin up an app in an online PaaS environment
  • Learn the context of SSH and URLs and components of online applications



What is the rational for this activity?

Students need to know what Cloud Computing really means, how it fits into the wider computing context, and what the different types are (IaaS, PaaS, SaaS). Students can dig into PasS, as a powerful development platform - and understand how quickly, easily, and powerfully they can spin up new applications. Gone are the days of having to setup a physical server, know the details on how to setup the OS, fiddle with the kernel, setup web-servers (Apache), databases (Postgres, Mysql), and middle-ware micros-services (AMQP Message busses, JBoss Fuse, Apache Camel). In a PaaS environment like OpenShift, the developer just fires up an instance of whatever pieces they want, and start coding. Seriously - its that easy. Of course, the developer has to know how to develop in said language or platform, but it makes development considerably easier by removing focus from lower layers. Basically, those lower layers (most mentioned above) are automated away by the PaaS platform.

We need an activity that can show students, step-by-visual-step, how to start up a new coding environment and actually code a small chunk of working software on Openshift. Make it something sexy, like Node.js. Make it an effective piece of code (contact someone within red hat for advise) and it would be even more amazing.
