Engine Yard, the Ruby-on-Rails automation and management start-up, has raised $19 million in third-round financing, pushing it total funding over 
$37 million.
Investors included Amazon, DAG Ventures, Bay Partners, Presidio Ventures (which is really Sumitomo), Benchmark Capital and New Enterprise Associates.
The money is meant to scale the Engine Yard Cloud, its self-healing application services platform for Ruby-on-Rails applications, for the enterprise.
The company has a yen to be the dominant platform for cloud computing, but then so does everybody else.
The money is also supposed to be used to build support for the open source JRuby development teams as well as other open source projects such as Rubinius.
