So I am starting to plan out how to launch services and stuff for apps and games and what have you. But there are a lot of questions with different opinions as to what is the best way to do things.

Maybe you could give some opinions and insight to some of these?

Web Requests:

the AGAPI and Apps will need many web requests. I used to use PHP, but I am thinking of using something more efficient.

Should I use Node.js? Does it need to be installed on the server? Seems to have a learning curve so it would take some time to get into.

Hosting:

So along with these requests, I wonder at what point I would need dedicated hosting. How many people can be using a think like agapi or other apps we are making at once? As a side note, I would consider bluehost.com as an alternative to godaddy prices, but I am not at that point yet.

Secure requests:

I am curious if anyone knows the best way to make secure requests to the server? I have been using a method of POST requests to url from the app, and using a hash with seed of the information to make sure that it is a legit request. I wonder if there is a better way to accomplish this task?

Monitors:

Would it be worthwhile to purchase a 1440p monitor? There are the "4K/UHD" monitors coming out recently, but I dont know if that is too much space where it would be annoying to manage windows on full screen haha. But I would like about a 7" with 1440p im thinking. Would be btter than leaning into my montor all the time

Thats all I have for now. Hopefully some people know what I'm talking about with this lol
