What is the best method to deploy a RASA chatbot that may be used less frequently?

Hi Community!

How do you go about deploying a RASA chatbot that has less traffic to it? i.e it is used infrequently throughout the day.

If I am using GCP or AWS, then I have to keep a server up throughout the day and that may be costly considering the actual usage of the chatbot.

Using free alternatives like Heroku won’t work because they only have 512 MB RAM for free usage.

What do you recommend?
