Please note for the purposes of this article, I'm largely going to ignore public clouds like AWS and OpenShift Online and focus instead on the on-premises side of cloud. Why? Well, back in the day, administrators used to deploy physical servers and thought that was great. Then, virtualization came along, and admins realized that deploying physical servers was a chore and that virtualization was the way to go.

Now, folks are moving into infrastructure as a service (IaaS) and deploying OpenStack internally, and being able to create a Heat template to deploy new systems in minutes is even easier! IaaS, however, is not the end-all. Platform as a service (PaaS) lets you largely ignore the operating system and network layers; ideally, you can specify something like "this application requires a web server, say, Ruby and Ruby on Rails for application, and some back-end data storage, so I'll go with MongoDB and memcached," and be done.

Often, application authors don't care, or want to care, about the underlying operating system or tuning things like the database server (e.g., one user might have a dedicated one, and another might be using a shared instance). PaaS lets application authors avoid these details, leaving them up to the PaaS layer.
