What is the difference between a dyno and a worker on Heroku?

On Heroku, a dyno refers to a lightweight container that executes the application code. It provides a single, isolated environment for running web or background processes. Dynos are responsible for receiving HTTP requests and handling web traffic or executing tasks. On the other hand, a worker is a specific type of dyno that handles background jobs or tasks that are time-consuming or resource-intensive. Workers are designed to process tasks independently from the web application, ensuring smooth performance. The primary difference between a dyno and a worker is their purpose and the type of processes they execute. Dynos handle web traffic, while workers are dedicated to background tasks, ensuring optimal resource allocation and enhancing the overall performance of applications on Heroku.
