Heroku enables developers to deploy applications using modern software design patterns for software-as-a-service. Applications benefit from continuous deployment with frequent code releases, easy management of dependencies, and configurability through environment variables. Heroku provides tools for managing data and services for building, running, and monitoring applications.
