Which freaking PaaS should I use?

By Andrew C. Oliver and Lifford Pinto, InfoWorld |  On-demand Software, paas

Most of the buzz around the cloud has centered on infrastructure as a service (IaaS). However, IaaS is no longer good enough. Sure, you can forgo buying servers and run everything virtually on Amazon's EC2 server farm. So what? You still have to manage it, and to do that you'll have a growing IT bureaucracy. Companies that want to focus on writing their code and not have to think about application servers at all are now looking to platform as a service (PaaS).

A PaaS is a virtual instance running an application server with some management and deployment tools in front of it. Management of the infrastructure and the higher-level runtime (application server, LAMP stack, and so on) are taken care of for you, and there's generally a marketplace of other services like databases and logging for you to tap. You just deploy your application and provision instances.

Amazon, Google, Microsoft, Red Hat, Salesforce.com, and VMware all have PaaS offerings. There are also smaller vendors such as CloudBees that are compelling. (We also wanted to try out Oracle Cloud, but when we attempted to create an account, the site reported that the preview was full. We look forward to trying it at a later date.) Each vendor has a set of differentiating characteristics beyond the many technical and cosmetic differences. They might even be targeting different sorts of customers. Which one should you choose?
