dynos

Dynos are lightweight, isolated units of computing resources used to run applications on platforms like Heroku. Think of them as individual containers that host your app’s code, processes, and services. Multiple dynos can work together to handle more users or tasks, providing scalability and reliability. They’re similar to virtual machines but more efficient, allowing your app to run smoothly without managing the underlying infrastructure. When you deploy an app, you allocate a number of dynos based on your needs, ensuring your application can perform consistently under different loads.
