What are some example of some better web servers

Answer 1

Edit: Correction to misinterpreted question. I'm not terribly knowledgeable in this field, but here are some considerations:
Apache:
- Long history, therefore tried and tested codebase.
- Apparently easier to develop upon.
- Heavier on resources (see architecture).
nginx:
- More modern. Designed for modern web with the full power of concurrency.
- So far as resources, nginx is lighter weight.
- More robust, but more complex.
General:
- They can work together. Like layers of an onion so I understand. An Apache server can be "wrapped" in an nginx one (via proxy), thus you get the best of both worlds.
- Honestly, it's better to move with the times and nginx is growing fast.
- Honestly, it's easier going from complex to simple than the other way around,

My verdict as a lay person: nginx (or both).
I am just a lay person, though. You'd do best to speak to an expert. Still, hope this helps.

Answer 2

Oops, my bad for not reading the question in context. I get so many people ask me, "What's the best OS for my server?" that my response has become generic. I've deleted that crappy answer and replaced it with something useful -- I hope.
