Heroku is a cloud platform as a service (PaaS) supporting several programming languages.

One of the first cloud platforms, Heroku has been in development since June 2007.

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, or Clojure.

Heroku Teams is a team management tool which provides collaboration and controls to bring a customer's developers, processes, and tools together in order to build better software.

Heroku Elements provides users with Add-ons (tools and services for developing, extending, and operating the app), Buildpacks (which automate the build processes for the preferred languages and frameworks) and Buttons (a tool for the one-click provisioning, configuring, and deployment of third party components, libraries and patterns).

Heroku Redis is the customized Redis from Heroku to provide a better developer experience.

Heroku Postgres is the Cloud database (DBaaS) service for Heroku based on PostgreSQL.
