Open source and cloud computing are two terms that everyone seems to be talking about. Powerhouses on their own, when paired together open source and cloud computing can create a developer’s dream scenario. In this session, Bret Piatt, technical alliances at Rackspace Hosting will discuss the history of open source software development and the spread of open source across the internet. Cloud computing providers are now incorporating open source into their business models through open APIs and contributions to various open source projects such as Cassandra and Drizzle, and Bret will discuss these developments while taking a close look at the intersection of cloud computing and open source to cover: How cloud computing is changing open source How cloud computing can benefit from open source How open source will lead the interoperability push How the success of cloud is tied to mass adoption that requires interoperability

2. History of Open Source

3. GNU to Linux (1983-1992)
"Bell Labs, the MIT AI Lab, UC Berkeley - these became the
home of innovations that are legendary and still potent."1
GNU Project GNU GPL Linux 0.12
Founded (1983) Issued (1989) Released (1992)
FSF Founded "The Hurd"
(1985) Released (1991)
"Linux was the first project to make a conscious and successful
effort to use the entire world as its talent pool."1
1) Quotes from "The Cathedral and the Bazaar", by Eric Raymond

4. The Internet Boom (1993-1999)
Linux becomes #1 server OS on the Internet1
OSS built in the boom continues today:
112 million websites running Apache HTTP Server2
24.23% of Internet browsing uses Firefox3
64.8M downloads of OpenOffice 3.14

2) As of 2/23/2010 http://blogs.apache.org/foundation/entry/the_apache_software_foundation_announces2
3) http://www.browser-watch.com/2010/03/02/browser-market-share-february-2010/
4) http://marketing.openoffice.org/marketing_bouncer.html

5. Open Source Era (1999-Present)
138 projects 150 projects
300 members 164 member companies
2000 committers 1179 committers
SourceForge.net®
230,000 projects
2,000,000 registered members
34,000,000 unique visitors monthly

6. The "hobby" of writing software
SourceForge and bowling leagues have the same number of members1
Over 8,000 plug-ins with nearly 80,000,000 downloads for Wordpress®
Over 4,000 add-ons created for World of Warcraft® listed on Curse.com
1) "More than 2 million compete regularly in league play certified by the USBC." http://www.bowl.com/about/index.jsp

7. Early in the life of OSS as a business
Only two "pure OSS" companies have gone public
VA Software (now Geeknet) Red Hat
Examples of major "pure OSS" acquisitions
MySQL (by Sun Microsystems) - $1B
SpringSource (by VMware) - $362M
SUSE (by Novell) - $210M

8. How Cloud Computing
Benefits From
Open Source

9. Communities form around problems
Cassandra (Rackspace, Digg, Twitter, Reddit, Facebook)
Hadoop (Yahoo!, Cloudera)
Xen (Citrix, Oracle, Fujitsu, Intel, HP, AMD, & more)
Eucalyptus (Eucalyptus, Canonical)

10. 1
"Release Early, Release Often"
Cloud designed RDBMS Drizzle builds constantly with Hudson
Service providers can patch
software -- no waiting for vendors.
Partners can do a complete
integration and understand how.
Customers can contribute bug
fixes and additional features.
1) Quote from "The Cathedral and the Bazaar", by Eric Raymond

11. OSS & cloud isn't a one way street
Many open source applications
work great "once running".
Cloud computing eliminates the need
to be an expert to try using OSS.
Time needed to get started
reduced from hours to minutes.
Cost to get started below
the price of a Happy Meal(TM).

12. Open Source
Is Leading Cloud
Interoperability

13. Do you like to be a hostage?
Don't design your system to use
features or technologies tied to a
specific vendor unless you want
a life sentence.
Let OSS abstract the underlying
foundation so your application
is portable across cloud providers.

14. OSS creates interoperability
Deltacloud Libvirt
Link virtualization & cloud Pick a hypervisor, any hypervisor
Libcloud
Write once, use many clouds
jclouds
Like Java, like many clouds?
Rackspace Cloud APIs
Specs any provider can use

15. Standards organizations cement it
Standards only emerge when the
result is available to everyone,
de-facto proprietary is not a standard.
Standards emerge slowly over time
and should avoid trying to solve
"world hunger", go domain by domain.
Service Providers need to collaborate
with the users in open discussion
and debate, un-conferences are
a perfect venue.

16. Cloud Needs
Mass Adoption
To Succeed

17. Cloud promises economies of scale
Wimshurst (19th Century) Nuclear (20th Century)
(AKA "Typical IT Environment") (AKA "Clouds of the Future")
VS.
Small clouds will not have the size to financially outperform
providers that can operate at massive scale. They won't be
price or feature competitive in the end.

18. Cloud requires scale
Cloud, like many other
industries has high upfront
costs in both expertise and
one time development
charges.
OSS amplifies this as it has higher
upfront implementation costs but
no additional per unit license costs
as services are scaled.

19. OSS driving interoperability will speed things up
For Cloud to reach the desired scale rapidly...
"Help me Open Source Software,
you're our only hope..."
Vendors with proprietary
technology that believe they
can corner the market have
no incentive to interoperate.
Service Providers, customers,
and enthusiasts that want an
open cloud computing world
need to work together.

20. Short Attention Spans
Meet the one minute summary

21. As promised, all in one minute
Section 1 - The History of OSS
OSS started in the early 80s and continues to grow today
Business takes time to evolve, just understanding OSS now
Section 2 - How Cloud Computing Benefits from OSS
OSS helps cloud through collaboration
Cloud helps OSS by making it easier to try and use
Section 3 - OSS is Leading Cloud Interoperability
Unless you want to be a hostage watch out
OSS is creating interoperability today
Standards organizations will cement it over time
Section 4 - Cloud Needs Mass Adoption To Succeed
Cloud promises economies of scale like the power grid
Cloud has high one-time costs
OSS driving interoperability will speed cloud adoption

26. CatB's 19 "rules" (suggestions)
1. Every good work of software starts by scratching a developer's personal itch.
2. Good programmers know what to write. Great ones know what to rewrite (and reuse).
3. "Plan to throw one away; you will, anyhow." (Fred Brooks, The Mythical Man-Month, Chapter 11)
4. If you have the right attitude, interesting problems will find you.
5. When you lose interest in a program, your last duty to it is to hand it off to a competent successor.
6. Treating your users as co-developers is your least- hassle route to rapid code improvement and effective debugging.
7. Release early. Release often. And listen to your customers.
8. Given a large enough beta-tester and co-developer base, almost every problem will be characterized quickly and the fix
obvious to someone.
9. Smart data structures and dumb code works a lot better than the other way around.
10. If you treat your beta-testers as if they're your most valuable resource, they will respond by becoming your most valuable
resource.
11. The next best thing to having good ideas is recognizing good ideas from your users. Sometimes the latter is better.
12. Often, the most striking and innovative solutions come from realizing that your concept of the problem was wrong.
13. "Perfection (in design) is achieved not when there is nothing more to add, but rather when there is nothing more to take
away."
14. Any tool should be useful in the expected way, but a truly great tool lends itself to uses you never expected.
15. When writing gateway software of any kind, take pains to disturb the data stream as little as possible - and *never* throw
away information unless the recipient forces you to!
16. When your language is nowhere near Turing- complete, syntactic sugar can be your friend.
17. A security system is only as secure as its secret. Beware of pseudo-secrets.
18. To solve an interesting problem, start by finding a problem that is interesting to you.
19: Provided the development coordinator has a medium at least as good as the Internet, and knows how to lead without
coercion, many heads are inevitably better than one.
