Heroku

Heroku is a container-based cloud Platform as a Service (PaaS) for deploying, managing, and scaling modern applications.

Heroku is a fully managed, container-based cloud Platform as a Service (PaaS) that drastically simplifies the application delivery lifecycle. Developers use Heroku to deploy, manage, and scale their applications without the operational burden of maintaining servers or infrastructure: it handles the complexity. The platform supports a polyglot environment (Node.js, Ruby, Java, Python, Go, PHP, Scala) and uses 'dynos' (smart containers) for application execution and scaling. Deployment is streamlined via Git, GitHub, or Docker, allowing teams to focus on code and business logic, not system administration. Key features include managed data services (Heroku Postgres, Redis), an Add-ons Marketplace, and seamless integration with the Salesforce ecosystem.
