What are the requirements for a laying server with nginx in a highly loaded project?

Question

Nginx

For example, there is a main server and a laying server with nginx through which all traffic goes.
The traffic is simply redirected by nginx, without any modification.
What parameters are critical in this case on such a server?
Should it have a powerful processor, the amount of RAM as on the backend (for example, 16 GB) - in order to simply redirect traffic?
What can be saved in this situation, and what can not be saved on? (taking into account the growth of the project)

Answer 1

If it's just forwarding, without SLL and other things, then you need a minimum of resources.
If with SSL, then you need a CPU, if with a cache, then memory.
If there are millions of permanent connections - then the memory, if there are millions of short sessions - then the CPU.
So simply according to your description of the server are not configured. Take either a small one and build it up or a large one and cut it off =)
