Jira Cloud add-on run continuously on website

[Vi Phung]

Hello there, 

I successfully created a simple add-on for Jira Cloud. I've been using a Linux box to connect/run the code from my local machine to Jira Cloud site. Now that it completes, I would like the code to run 24/7. Have anyone done this? I am not sure how/where I can use to have the add-on run all the time. 

Thank you for your time!
