Heroku is a container-based cloud Platform as a Service (PaaS). Developers use Heroku to deploy, manage, and scale modern apps. Our platform is elegant, flexible, and easy to use, offering developers the simplest path to getting their apps to market.
Why is Heroku free?
Heroku's free cloud services begin with the apps - apps which can be deployed to dynos - our lightweight Linux containers that are at the heart of the Heroku platform. When you sign up with Heroku, you automatically get a pool of free dyno hours to use for your apps. When your app runs, it consumes dyno hours.
Buildpacks are composed of a set of scripts that will perform tasks such as retrieve dependencies or output generated assets or compiled code. If you are using a language that is officially supported by the Heroku platform, the build system will automatically detect which Heroku Buildpack is needed for the job.
The Heroku network runs the customer's apps in virtual containers which execute on a reliable runtime environment, Heroku calls these containers Dynos. These Dynos can run code written in Node, Ruby, PHP, Go, Scala, Python, Java, Clojure. Heroku also provides custom buildpacks with which the developer can deploy apps in any other language. Heroku lets the developer scale the app instantly just by either increasing the number of dynos or by changing the type of dyno the app runs in.
