We will analyze hosting for application deployment

How much will it cost to host an app such as a telegram bot that consumes 300 MB of RAM?

Amvera Cloud - 290 rub. (~3$ per month)
Heroku - 25 $ per month
Clever Cloud - 6 euro per month
Application engines from Azure, GCE, AWS and Digital Ocean - The engines themselves work for free, but you have to pay for virtual machines, which start at
