Heroku Runtime
Heroku runs your apps inside dynos — smart containers on a reliable, fully managed runtime environment. Developers deploy their code written in Node, Ruby, Java, PHP, Python, Go, Scala, or Clojure to a build system which produces an app that's ready for execution. The system and language stacks are monitored, patched, and upgraded, so it's always ready and up-to-date. The runtime keeps apps running without any manual intervention.
Heroku Developer Experience (DX)
The Heroku Developer Experience is an app-centric approach to software delivery so developers can focus on creating and continuously delivering applications, without being distracted by servers or infrastructure. Developers deploy directly from popular tools like Git, GitHub or Continuous Integration (CI) systems. The intuitive web-based Heroku Dashboard makes it easy to manage your app and gain greater visibility into performance.
Data Services and Ecosystem
Heroku Elements let developers extend their apps with Add-ons, customize their application stack with Buildpacks and jumpstart their projects with Buttons. Add-ons are 3rd party cloud services that developers can use to immediately extend their apps with a range of functionality such as data stores, logging, monitoring and more. Heroku provides two fully-managed data service Add-ons: Heroku Postgres and Heroku Redis.
