Acquired by Salesforce in late 2010, Heroku supports Ruby, Node.js, Clojure, Java, Python, and Scala development. Heroku leverages "dynos" -- processes of any type running on the platform, such as Web or worker processes. Dynos are isolated in their own container for security and resource guarantees; they also feature elasticity, routing, and process management. Dyno distribution is done via a dyno manifold execution environment. Heroku Web scaling offers instant spin-up, infinite capacity, and scaling for each component of an app, according to Heroku documentation. Git is the primary means for deploying apps to Heroku, and apps can use relational database services, including Heroku's Postgres offering and MySQL from Amazon Web Services.
