How to choose a server (hardware) for your needs?

Question

Highload

A question for professionals and all lovers of benchmarks.
There was a question to buy iron and take it to the data center and provide yourself with your own server.
In the choice of performance and iron, I'm not very strong.

The server is needed to provide API (NGINX/PHP-FPM), load 300-700 requests per second.

Therefore, the question is: is it worth taking a processor 2 x Intel XEON 10 Core E5-2690 V2 3.00 GHz (SR1A5) and 64 GB RAM (used) the issue price is 1.8k dollars or choose for that kind of money, something simpler but with more recent processor? And is there enough power for my needs?

PS : maybe there are some calculators for calculating the power of iron for the needs of the server?

Answer 1

No calculator will calculate the allowable load on your application, only spherical parrots. The easiest way is to rent a server from a hoster (or get it somewhere else), pile your software on it and arrange load testing. Based on the results, it will become more or less clear how much cooler iron is required. Or maybe not needed.

Answer 2

Pay very close attention to the real resource of the hard drive. The advertisement is lying. Many are stumped on this. And it was with me =(

Answer 3

At the present time, renting iron is cheaper than buying it and colocation
