Distribution A Dialogue on Distribution

Summary: Part IV
A Dialogue on Distribution
Professor: And thus we reach our final easy piece in the world of operating
systems: distribution.
Student: But what is distribution, oh glorious and all-knowing professor?
Professor: Well, I bet you know how this is going to go...
Student: There's a peach?
Professor: Exactly! But this time, it's far away from you, and may take
some time to get the peach. And there are a lot of them! Even worse, some-
times a peach becomes rotten. But you want to make sure that when any-
body bites into a peach, they will get a mouthful of deliciousness.
Student: This peach analogy is working less and less for me.
Professor: Come on! It's the last one, just go with it.
Student: Fine.
Professor: So anyhow, forget about the peaches. Building distributed sys-
tems is hard, because things fail all the time. Messages get lost, machines go
down, disks corrupt data. It's like the whole world is working against you!
