Heroku, the San Francisco based platform as a service startup, has just announced it has raised an additional $15 million in the second round of venture capital investment.
As one of the first cloud providers, Heroku were incubated in Y-Combinator, following an investment round of $5 million afterwards.
Heroku is currently hosting over 60.000 app on their service. Anyone can host for free an app there, as long as their database doesn’t exceed 5MB of storage.
The system provided by Heroku offers the simplest deployment and scalability solution for Ruby on Rails, by pushing the app via Git and moving up and down a couple sliders when additional concurrency or background processing is needed.
Many people see the investment actually being directed at Ruby and Ruby on Rails, and as a bet to the future that more and more startups will choose this framework and programming language and host their apps in a cloud environment as opposed to dedicated servers.
