How and where to buy power?

Question

Network administration

Hello.
There was a need to deploy a simple C # application (Web API) for a mobile game with a database (a table for storing a couple of hundred instances of a structure of 5 text fields) and cloud storage (for storing a couple of hundred files ~ 1MB each).
I don't know how much power is needed. The only information is about 200,000 unique users every day.
I saw micro tariffs on AWS for ~ $ 50 / month - is that enough?
Where to look? What to read?

Answer 1

It is not known whether enough or not - it is necessary to measure. But in AWS, you need exactly 2 things - to be able to set up horizontal scaling and do it right. Otherwise, this $ 50 is just the beginning)
In general, I will definitely advise AWS, it is good in any use case, you just need to use it correctly. I can tell you separately with the architecture, but with the calculation of power without current measurements, I can’t say

Answer 2

I don't know how much power is needed. The only information is about 200,000 unique users every day.

It is impossible to achieve such an amount from scratch. Users come gradually.
We take a cheap tariff, then gradually change it to a higher one as the load grows.
Modern hosters allow you to change tariffs even on the fly.
There can be no pre-assessments.
Maybe you have a very well-written application and a server for $10 per month is enough for 1 million users.
Or maybe you have a shithead. Where every 1000 users will require +$500 per server.
Run and try.
There are hostings with hourly payment even - you won't lose much.
In any case, save more due to the fact that you will not overpay for unnecessary resources.
