Re: proposal: unik & cloud foundry

Hi, Idit,

Is there any updates on the concerns Daniel raised? Also, note comments in

According to our process, when comments are not addressed, proposals become
stalled and then are subject to be removed from CF-extensions consideration.

Thanks in advance for addressing all comments.

Hi Idit,

Thanks for sending out the proposal, and thanks for giving your talk in
Santa Clara last year, which I attended and was excited by.

I've read the proposal and heard the talk, but I'll be frank - I still
don't get it. That may well be because I'm a simpleton who doesn't know
much about kernels, let alone unikernels, but if I don't ask some silly
questions I'll probably never know.

- Cloud Foundry aside, how does Unik go from receiving some app code
to know exactly which kernel features are needed for the application at run
time? This is the part that seems most magical to me.
- Where is the Unik daemon running - presumably somewhere of the
operators choice, mostly likely as a BOSH-deployed job?
- What happens if the Unik daemon dies - is it stateful? Will
unikernels continue to run and be manageable?
- Does the unikernel image get created at app staging time?
- Has there been any discussion about how to strategically implement
this alongside Diego, instead of the tactical solution of 'going through'

I'm excited by the promise of unikernels - being able to cut out so much
bloat and indirection would be a massive win for efficiency if they usurped
containers as a unit of currency. I wonder how much CO2 emission we could
avoid by stripping abstraction away, instead of piling it on!

Thanks for this submission Idit and Dell/EMC.

I look forward to comments from community as we work this though the
CF-extensions process.

One clarification, we propose it to the CF incubation program.

Hi all,

We at Dell EMC would like to propose to contribute project unik ( and its integration with Cloud
Foundry ( to Cloud
Foundry community.
