I was recently shopping around for inexpensive cloud hosting; I want to try out a couple of ideas that may or may not have much traffic, but which aren't suited for my VPS setup (the excellent ServerGrove); additionally, I'm unsure how long I will maintain these projects. My budget for this is quite small as a result; I'm already paying for hosting, and am quite happy with it, so this is really for experimental stuff.
I considered Amazon, Orchestra.io, and a few others, but was concerned about the idea of a ~$50/month cost for something I'm uncertain about.
When I asked in #zftalk.dev, someone suggested OpenShift as an idea, and coincidentally, the very next day Zend announced a partnership with RedHat surrounding OpenShift. The stars were in alignment.
In the past month, in the few spare moments I've had (which included an excellent OpenShift hackathon at ZendCon), I've created a quick application that I've deployed and tested in OpenShift. These are my findings.
