Heroku is a cloud @Platform as a Service (PaaS) that enables developers to build, run, and operate applications entirely in the cloud. Originally launched in 2007 and later acquired by @Salesforce in 2010, Heroku supports multiple programming languages, including Ruby, Node.js, Python, Java, PHP, Go, and Scala. The platform simplifies deployment by abstracting server management and infrastructure, allowing developers to focus on code rather than configuration. Applications are run in lightweight containers called “dynos,” which can be scaled horizontally or vertically to accommodate demand. Heroku integrates with a marketplace of add-ons for databases, caching, logging, monitoring, and other services, making it a flexible choice for rapid development and experimentation. It is known for its simple Git-based deployment model, developer-friendly interface, and strong alignment with agile and continuous delivery practices. Heroku remains a widely used platform for startups, hobby projects, and enterprises seeking quick iteration without the complexity of traditional infrastructure management.
