I am planning to run a web server any advices to share with me?

[Kiran Sehzadi]

First of all I don't want this question to be posted in off-topic.

To make it simple, I'm simply saying that I've plan to run a web server after crossing to an article how to set it up.
summary
I don't have a first hand experience setting up a server, but after witnessing the said article it was sort of easy to understand especially that I know how Linux/Ubuntu work.
question
I want to know exactly if is it possible to run a web server if the my internet connection have a data capped/limit with only 800mb per day?
to make it more simple does it affect my internet data if someone is roaming around the site? generally I want to make a forum exclusively in my local country but I have a consumable 800mb.
bottomline
I doubt if anyone have tried this before on a limited internet connection but I need ideas. bandwidth is not a problem I could just use a 1terrabytes for it.

How many visitors do you expect, and how many megabytes, on average, do you expect each user to download? Running your own server is a great way to learn, but 800 megabytes per day is really peanuts for a web server. I’m assuming upstream traffic (stuff your server would send to your visitors in response to their requests) also counts against your quota.

In any case, also remember to secure your server. Use updated software and apply safe configuration options so that your server won’t be compromised

I think to open a website like that must be secured using anti hacking.

Even a class of cryptocurrency that has a lot of sophisticated hacking is cracked, let alone just a website, it's easy to use MySQL injections.
