opsworks_ruby – manage Ruby deployments on AWS OpsWorks Chef 12 stack

Half a year go, AWS dropped their out-of-the-box support for Ruby applications. It is still remaining in the Chef 11 stack, but if you wish to use a new Chef 12, you are on your own. That’s where opsworks_ruby kicks in - it allows you to leverage all the goodies of AWS OpsWorks (like applications, layers, connected RDS etc.) just the way Chef 11 stack did, without any extra JSON configuration. This is a much simpler solution, than implementing your own recipes (like application_ruby for example) and keep track of all those JSONs all the time. And besides, it includes many framework, web and app servers out of the box. [more inside]
