Using Perl on Red Hat's OpenShift Cloud
Are you a lone Web developer who has a great idea for an app but you're intimidated by the idea of getting a Web server, maintaining the OS, installing the database, handling DNS, keeping up to date with security patches and so on? Instead, you can try a Platform as a Service (PaaS) system and let them handle the system administration stuff while you focus on just writing your code.
I wrote a short guide on how to write Perl applications for Red Hat's OpenShift PaaS cloud service. It turns out that it's really, really easy. And the basic service is free!
