server configuration strategies
While this isn't exactly on the topic of _debian_ ISPs, it is related
to ISPs running Linux in general.
I'm running a very small ISP. I mainly only host domains for clients
I consult for; no dial-up. I add machines to my "server-farm" as I
can. I usually buy pre-owned equipment to save on costs (since all of
my capital comes out of my profit). For instance, I have an old Sun
SparcServer 20, Apple PowerMac 9300, and a K6-III/450 (they all run
debian). None of these machines are speed demons; but, they get the
job done. As I get more load, I'm thinking more and more about the
upgrade path.
Are there any strategy guides that talk about how/when to split up
services on differnet servers? Are different platforms better at
different tasks (like network I/O, disk I/O, cpu)? For instance,
when do you decide that your database should be moved off your web
server? When should mail be split out? How do you know how much
cpu/RAM you need to handle all your mail traffic? How do you know how
many hits/hour a particular apache box can serve?
My guess is that this is all a matter of personal tastes/experiences.
In my case, you get a box and put stuff on it. If it's loaded (using
top or something) you try and move stuff off of it.
