Re: [Publicity] A thought piece: Docker and Unikernels



Sarah/Libby,

I've attached a slightly modified post.

I'd rather see this in Linux.com rather than XenProject.org so it won't be mistaken as an "official" Xen Project position.

Regarding Amir's comments:

I've finally had the time to give your comments the consideration they are do.  And, while I see your argument and look forward to your development of the concept into a substantial article somewhere (and I am sure the XenProject.org blog will be happy to publish that piece when you have it completed), I don't feel I should severely modify the piece I've written.

Amir is rightly concerned that my post will be perceived as a (rather myopic) official position paper.  In fact, it is nothing of the sort.  I've written many such pieces over the years to call out what I perceive as dangerous errors in a populist "hive mind" position.  The purpose of the piece is to cry, "Whoa!" to a team of horses which are in danger of inciting an ill-considered stampede.  The carefully detailed whitepapers describing a meticulous counter proposal are still needed, but they will not be heeded until the crowd in motion slows down enough to read.

My piece is the cry to slow things down.  I look forward to Amir's piece (and others) which give us a reasoned argument for a better direction.  But those pieces will be ignored and trampled unless we can first halt the stampede and get people to slow down enough to heed reason.

Amir, I have pitched a talk for CPOSC in November about the rise of the unikernel.  I'd be thrilled to see how your workflow justification matures so I can possibly incorporate elements of your thought into that talk (with attribution),  I believe a talk like that would be an excellent place to introduce a more logical positioning of unikernels.

Hi Russ,

Do you have a revised, updated blog to share? If so, please email it so I can review it again. Might want to publish today or tomorrow to catch some of the VMWorld momentum.

There is just enough code to make the application run, and precious little for a malefactor to leverage.  All the code that is present is statically type-safe, from the application stack all the way down to the device drivers themselves. It's not the “end-all be-all” of security, but it is certainly facing the right direction.

They can be viewed as the natural evolution of Linux containers - maintaining their packaging and deployment benefits, but adding much more specialization into the mix to reduce resource wastage and external attack surface.
