What is container in general

It is a lightweight, isolated environments that provide compute, memory, an OS, and an ephemeral filesystem. Containers are typically run on a shared host, yet are completely isolated from each other.

What is Dyno in Heroku

The containers used at Heroku are called “dynos.” Dynos are isolated, virtualized Linux containers that are designed to execute code based on a user-specified command. Your app can scale to any specified number of dynos based on its resource demands. Heroku’s container management capabilities provide you with an easy way to scale and manage the number, size, and type of dynos your app may need at any given time.

Scale your deployed app

Ensure that at least one instance of the app is running

heroku ps:scale web=1

Scale app in cloud

Open your app

Write below command to open your application url live cloud based.

I like the simplicity and easy steps to deploy an app on Heroku Cloud. Their documentations are excellent source of learning. I did deploy my first node.js app over Heroku as well See my app live here
