Heroku is a cloud platform-as-a-service (PaaS) founded in 2007 and acquired by Salesforce in 2010 for $212 million. Heroku pioneered the modern PaaS model, enabling developers to deploy applications without managing infrastructure.
Heroku offers container-based deployment, managed databases (Postgres, Redis), add-on marketplace, and CI/CD pipelines. The platform is popular for prototyping, startups, and side projects.
Heroku's infrastructure runs on AWS, providing an abstraction layer for deployment. The platform has faced criticism for ending its free tier but remains popular with developers.
DNS for heroku.com uses Amazon Route 53 with global distribution. Heroku also provides SSL and custom domain support for customer applications.
