This document discusses OpenStack, an open source cloud computing platform. It provides details on several OpenStack projects including Nova (compute), Swift (object storage), Glance (image service), Keystone (identity), and Dashboard (web-based UI). It shares code statistics for some of the projects and discusses DevStack, a tool for quickly deploying OpenStack locally. The document emphasizes that OpenStack is a framework that requires choices around architecture, functionality, configuration, and more. It also discusses challenges around networking, storage, provisioning, and reliability.

27. 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 sessions
Are you down with RCB?

28. so you really want to
build a cloud?

29. We writes
the codes
we hates the servers

30. Freedom!

31. cool story, bro

can’t be clouds
all the way
down...

33. Someone
has to
make it
work...
It puts the scalability in
the basket or it gets the
hose again...

34. doing it
wrong
seriously, just say no

35. the secret sauce:
‘there is no secret

Progress comes to those who train and train;
reliance on secret techniques will get you
nowhere.

Compromise?

37. Networking
how does it work?
soooo many choices

38. Storage
hard problem

43. you have to solve this
both in and out of the cloud
might as well leverage the community
No?
