Heroku Platform

The Heroku Platform, now from Salesforce, is a platform-as-a-service based on a managed container system, with integrated data services and ecosystem for deploying modern apps. It takes an app-centric approach for software delivery, integrated with developer tools and workflows. It’s three main tool are: Heroku Developer Experience (DX), Heroku Operational Experience (OpEx), and Heroku Runtime.

Heroku Developer Experience (DX)
Developers deploy directly from tools like Git, GitHub or Continuous Integration (CI) systems without the need to manage infrastructure. The web-based Heroku Dashboard makes it possible to manage applications online and gain visibility into performance.

Heroku Operational Experience (OpEx)
OpEx helps developers troubleshoot and remediate issues and customize the ops experience to identify and address trends in application health. Heroku provides a set of tools to alert teams if something goes wrong, or to automatically scale web dynos if the response time for web requests exceeds a specified threshold.

Heroku Runtime
Heroku runs apps inside dynos—smart containers on a 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 then monitored, patched, and upgraded. The runtime keeps apps running without manual intervention.
