Why does cloud matter beyond AWS, Azure, and Google Cloud?


https://www.schneier.com/blog/archives/2014/06/chinese_hacking_1.html

Industrial Espionage

“Chinese hacking of American computer networks is old news. For years we've known about their attacks against U.S. government and corporate targets. We've seen detailed reports of how they hacked The New York Times. Google has detected them going after Gmail

accounts of dissidents. They've built sophisticated worldwide eavesdropping networks. These hacks target both military secrets and corporate intellectual property. They're perpetrated by a combination of state, state-sponsored and state-tolerated hackers. It's been going

on for years. ”- Bruce Schneier(Emphasis mine)


Many enterprises want to control and lock down at least part of their cloud

presence.

You could standup OpenStack yourself or………


Use A Distribution

http://www.openstack.org/marketplace/distros/


Numerous public clouds around the world

Choose Your Own Adventure

1. Build Apps For OpenStack

2. Contribute to OpenStack

3. Standup OpenStack

So, You Want To Build An App For OpenStack


The OpenStack APIs are “basically” the same everywhere


Start with DevStack or a public cloud


developer.openstack.org


Use An SDK … if one exists


API permutations can and do happen

Ask Questions… ask.openstack.org


Or use IRC wiki.openstack.org/wiki/IRC


So, you want to contribute to OpenStack itself…


DevStack Environment


Make sure you have enough hardware horsepower


Setting Up DevStack1. Start with Linux (eg., Ubuntu)

2. Clone DevStack$ git clone https://github.com/openstack-dev/devstack.git

3. Create a config (what services and what they use )

4. Start DevStack$ cd devstack; ./stack.sh

5. Start Using It


Let’s start with Github


Github is a mirror


Gerrit – review.openstack.org


Who Uses Gerrit?


Zuul - status.openstack.org/zuul/


Get Setup in Gerrit


How To Start Hacking On OpenStackInstall git-review$ pip install git-review

Get a project to work on$ git clone git://github.com/openstack/horizon.git

Work on a branch (bug/[bug id] or bp/[blueprint name])$ git checkout –b TOPIC-BRANCH

Make changes which should be in a single commit then send for review$ git review


The Review on review.openstack.org


The Tests and Reviewers


Update A Change (alternative to pull request)Get the changeset up for review$ git review –d 1234

Make changes and amend commit$ git commit -a --amend

Send updated changeset to Gerrit$ git review


The same review contains the patchset history


Jenkins handles all merges


So, You Want To Standup OpenStack…


Why not use a distribution?


If It’s Just For Development


Standing up OpenStack is like building your own Linux Distribution
