Here's a video of my OpenShift PaaS session from Developer Exchange day in Boston. It's something I've delivered a bunch of times - I hope you enjoy it!
Session Abstract:
Tired of waiting weeks to get a server or spinning up and configuring your virtual servers. Come learn about how PaaS can make you into a happier and more productive coder. We will start by teaching you the meaning behind some acronyms you see thrown around - IaaS, PaaS, and SaaS. Next we turn to PaaS and talk about why it is a developers dream come true. From there we will use Red Hat's Open Source PaaS, OpenShift, to demonstrate how easy it is to get started with a PHP web application. This will be about 1/3 slide and 2/3 demo and code in action. Bring your laptop if you want to follow along - it is that easy. If time permits we may also show a little bit of working with MySQL and PHP on OpenShift. Come in skeptical leave with a smile and some working code.
