Open Source and CloudThe Two Great Tastes...

April 6, 2012 The Future of Gluster.org - John Mark Walker

WTF is Cloud

Cloud is a distributed and automated service deliverysystem

Origins:

Increasing emphasis on automation Increasing reliance on network services

Increasing commoditization of hardware andsoftware components

Increasing scale-out of operations Goals: flexibility, agility, automation and economies

of scale


3/31

WTF is Open Source

Open source: distributed software developmentsystem Origins:

Increasing commoditization of software +downward price pressure Increasing connectivity and knowledge sharing

between interested parties Increasing demands for easy adoption

Deploy first, ask questions later A sprinkling of advocacy

Goals: quicker development, economies of brainscale, defining (and defending) fair marketplace


4/31

What They are not

Open source != distribution system

Freely available != open source

See, eg. Splunk

Cloud != virtualization or any specific type of software

Automated, scalable service delivery over a

network


5/31

Similarities of OSS and Cloud

Both reflect a changing landscape in the datacenter towards automation and agility

Both reflect increasing independence on thepart of developers and operations

Both also drive more of the above Positive feedback loop for more data

center automation


6/31

Similarities of OSS and Cloud

Open source facilitates adoption-led model

Cloud computing thrives on an adoption-led

model Open source facilitates faster development

Cloud computing thrives on faster

development


7/31

Theories, Hypotheses and otherHeretical Things

Hypothesis #1:

Cloud computing is not possible without opensource

How do we test?


8/31

Party Like It's 1998

You have a really cool research project atStanford, do you...

A.) buy lots of expensive proprietary software,

hardware and hope the investors don't mind B.) DIY with lots of custom glue around freely

available open source bits


9/31


Pros and Cons of A:

Con: It's really expensive

Con: It's difficult to change course

Pro: Will (probably) be easier to deploy, configureand admin

Conclusion: how much is your business agilityworth?


10/31


Pros and Cons of B:

Con: It's really expensive

Con: A lot of necessary customization

Con: Domain experts are essential

Pro: I can do whatever I want

Change on a dime; mix and match vendors

Conclusion: how much is your agility worth?


11/31


It's not about up-front cost

It's about agility, fast adoption, iterative coursecorrections, no gatekeepers

Ergo, Open source is necessary for cloud toexist

Prediction: every cloud player will utilize opensource on a massive scale


12/31

The Cloud Ecosystem

What major companies couldn't exist as weknow them sans open source?

See Paul Krugman's work on geographicimpact on economies

Geographic ecosystems emerge and benefit eachother


13/31

Impact of Cloud

The opposite isn't true

Cloud isn't necessary for open source to exist

What is the impact of cloud on open source?


14/31

Impact of Cloud

3 possible hypotheses:

cloud computing deemphasizes software ingeneral, therefore will reduce production and/orconsumption of open source software

cloud computing will neither augment nor reduceproduction and/or consumption of open sourcesoftware

cloud computing will increase the production andconsumption of open source software


15/31

Impact of Cloud

I chose #3! Prediction: cloud computing will speed up the

development of open source software


16/31

Hypothesis debunking

Hypothesis: cloud computing deemphasizes software in general, thusreducing need for open source software

yes, local software and traditional desktops are less relevant

Local computing is also a delivery model, like cloud

BUT - open source isn't a delivery model, it's a development model

Cloud computing still needs to run software And cloud demands efficiency and agility

open source will continue to be utilized to build cloud-y services

Prediction: open source will continue to dominate cloud computing, andthe need for open source software will only increase


17/31

Hypothesis debunking

Hypothesis #2: cloud computing will have no impact on opensource software, because they're orthogonal

Yes, yes, one is a delivery model, the other is a developmentmodel, therefore there's no causal connection, right?

competition == increasing demands for agility and efficiency ==open source

competition drives community participation

increasing popularity of cloud computing will drive increasing usageof open source software

separation of services from software actually makes thiseasier ie. Open core is dead


18/31

Hypothesis Bunking

Hypothesis #3: cloud computing drives more open sourcesoftware + participation

if #1 and #2 are false, then #3 must be true!

if open source software gives companies more agility and helps

them deliver services more efficiently, then there is definite ROI therefore, a company would be foolish not to invest in open

source development

the adoption-led model of open source ties directly into the credoof cloud computing:

build first, ask questions later


19/31

The Outer Limits

Ok fine, Open source begets cloud, whichbegets more open source, now what?

Will cloud services be open sourcedthemselves?

What does that even mean?


20/31

The Outer Limits

Let's review the software world: Remember 1999? Whathappened?

Linux started the long trek to glory in the data center

So did apache

And MySQL. And PostgresQL

And later Mongo, Hadoop and GlusterFS :)

And lots of other infrastructure technologies

But open source never took over the desktop/workstation


21/31

The Outer Limits

Huh? Android! New mobile paradigm!

The apps are, alas, mostly non-free

Prediction: cloud services, like mobile apps anddesktop applications, will remain mostlyproprietary/non-free


22/31

23/31

Open Source in Cloud-y World

What does open source mean in a cloud-y world?

Hypothesis: in a world where the distinctionbetween copyleft and liberal licensing is

diminished, liberal licensing will grow

I, for one, welcome my new Apache overlords.


24/31


GPL was made for local computers

delivering a service over a network does notconvey software, according to the GPL v3

the central driver of vanilla GPL is obviated

Apache licensing will continue to grow


25/31


The Affero GPL was created to address this

closes the service provider loophole

copyleft in a cloudy world

is it enough?


26/31


27/31

Lock-in The world is full of monopolies

No such thing as frictionless economy

Data represents the exit blocker

Entity 1 Entity 2 Entity 3

Entity 4 Entity 5


28/31

Open Source in a Cloud-y World

Is there an economic driver for Open Data?

Hypothesis: er... maybe? In some cases.

In some social media cases, maybe walled

gardens do not lend themselves to totalopenness

Too much value in keeping some data locked up

Will competition prove the difference?


29/31

Open Source in a Cloud-y World

Is there an economic driver for Richard Stallman?

Probably not

Why is email (mostly) free?

Competition drove adoption of email standards


30/31

Summary

Open source enables cloud computing

Cloud computing, in turn, enables more opensource

May not graduate to the service/app/data layer NEEDZ MOAR RICHARD STALLMAN
