use cases

wager most people are interested in…

Nova

stack.sh: shell scripted source install

quickest path to running code that is accessible to change

see everything that gets installed and configured

nova services, glance, keystone, dashboard and munin

runs all the services in named screen sessionsAre you down with RCB?

so you really want to build a cloud?

We writes

the codes

we hates the servers

Freedom!

cool story, bro

Compromise?

Cost

Performance

Failure

Networkinghow does it work?

soooo many choices

Storage

hard problem
