I've pasted the text from that page below so we can comment on it inline. One of overall comment I have is that the "buildings" analogy is a misleading analogy and leads to false conclusions. Rather than using any analogy it would be better to describe what it is and what is actually happening. This is part of the problem with public cloud is people are already, for various reasons, falsely not acknowledging that running on a public cloud is doing your computing on top of Software, that you can't inspect the running copy, on hardware you don't have access to, made available as a Service. > * Cloud * www.d.o-draft * philoshphy > > Draft for a "philosophy", "freedom", or "viewpoint" page about clouds > on www.debian.org > > Having a private cloud is like owning a bunch of buildings on your > own land and keeping most of them empty most of the time. If you run a private cloud you don't need to "keep them empty most of the time". You can have your running VMs expand and shrink their resource usage as hardware resources allow, when they are less crammed in they will (mostly) run better. You can run lower importance computing jobs less or more depending on how much higher importance jobs there are. You could run DACA stuff, DI tests, test FTBFS and/or some lower importance CI tasks with any spare resources. > Putting some servers into a data-centre is like owning a bunch of > buildings built on land rented from someone else. > > Using IaaS (public cloud) is like renting an empty building with the > usual utilities; electricity, water, gas. > > Using PaaS is like renting a pre-furnished room in a building. > > Using SaaS is like visiting the library, post office or a > restaurant. This is where the "buildings" analogy really breaks down, leads to false understanding and false conclusions. What using public cloud *is* (rather than perhaps what people would like to pretend it is) is doing your computing on top of Software, that you can't inspect the running copy, on hardware you don't have access to, made available as a Service. This is the same whether what is being used is a spreadsheet, a programming runtime environment or a cloud computing solution. It is the very antithesis of what the Free Software Movement is about. Let's remember the initial press release draft press release: > <p> > As you may know, starting with the upcoming stable release <q>Wheezy</q>, > Debian will <a href="http://www.debian.org/News/2012/20120425";;>make > it easier for its users to deploy private clouds</a>. > As a free software project, we care deeply about the freedom of our users > and we recommend to them to run their own private clouds whenever possible. > </p> > > <p> > While we recommend running your own cloud Unfortunately, this was shouted down. But it makes it so clear that a cloud computing solution *is* Software. The software to do a cloud computing solution is in main in wheezy. That Debian is a free software project and committed to the freedom of its user. And has the statement that if you are going to run a cloud computing solution then Debian recommends you do it on your own private cloud, which fits with Debian's commitment to the free software community. > Everyone makes a trade-off when they decide where in the spectrum > they feel comfortable with.

I disagree with pretty much everything in this bit! Is this really about "trust in society"? Are the public cloud providers society? Is wanting to be free a trust issue? Would you make the same statements about non-Free Software? Should Debian? Are people not wanting to run non-Free Software just not "trusting" enough? What about instead saying "it all comes down to how much you value your freedom.". > I think that it would be nicely complemented by a final paragraph > explaining how Debian support the use of Free software at various > levels of trust in the cloud systems.

The reason for main, contrib and non-free is more than non-free firmware but also non-free software. Perhaps there should be a 'saas' archive, this wouldn't have anything in it or all the packages would be empty because with SaaS you don't even get the executing software. This would help bring clarity to the situation for many. My argument would be that running on public cloud is a bit like running on one massive non-free firmware blob (only worse, of course, as explained). I would hope that Debian would, if it is provides support for public clouds, at least say on cloud computing that it is preferable to run a private cloud. > Debian is the > universal operating system, which can operate a network > infrastructure, virtualised hardware, cloud systems, remote services, > and the client systems that access them." Probably the word "provide" rather than "operate". > This misses Free hardware. Do we distribute packages that are > related to the conception and production of free hardware ? Here is one: http://packages.qa.debian.org/g/geda-gaf.html In conclusion, please could we have a statement in the sentiment of the original press release draft, available at: https://lists.debian.org/debian-cloud/2013/03/msg00000.html which is more in keeping with Debian's philosophy. I think the subscribers here might not be reflective of the views of the project as a whole. Please could the statement be posted to a list where it will receive more project wide feedback before it becomes the official statement. And I urge people to read "Who does that server really serve?" <http://www.gnu.org/philosophy/who-does-that-server-really-serve.html>. Regards, Mike. P.S. If you ever thought that Open Source and Free Software "are the same thing" then hopefully this discussion dispelled that, see "Why Open Source misses the point of Free Software" <http://www.gnu.org/philosophy/open-source-misses-the-point.html>. -- FSF member #9429 http://www.fsf.org/register_form?referrer=9429 http://www.fsf.org/about "The Free Software Foundation (FSF) is a nonprofit with a worldwide mission to promote computer user freedom and to defend the rights of all free software users." -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
