Yup, If you're running unikernels in a VM for "improved performance" you're doing it wrong. Containers are a much better solution. Unfortunately people see containers now as a packaging mechanism rather than an alternative to hardware virtualization. Also doesn't help that everyone runs their applications in The Cloud where you're required to run on a VM. I'd really like to see containers services like Joyent's take off.

Interesting. I'd like to see a return to owning/renting whole machines and running containers on them directly (as several major tech companies do). A lot of the value proposition for the cloud service providers is a multi-host hypervisor that's really easy to get started with (compared to buying vSphere). If it becomes really easy to deploy your own instance of an open-source container scheduler across your own boxes, we can return to cost-competitive commodity boxes instead of overpaying for AWS.
Agreed, private cloud systems that leverage OS level virtualization like Joyent's solution is completely production ready from a software perspective. IMO, the biggest challenge past getting CTO approval is finding production 24/7 support for the complete stack.
For SMB private clouds, its a no-brainer; I just buy a FreeNAS or TrueNAS box (FreeBSD based) from iXSystems and have them customize the box for extra ram and CPU. You get ZFS, DTrace and a wicked NAS, OS level virtualization with jails and even linux binary support if required. I've done this successfully in production and could not be happier.
Note: I don't work for iXSystems but I do love their products and services.

Same here, especially since the zones that the Joyent containers are built on are really easy to use and provide entire miniature yet full fledged UNIX servers, not to mention itβs all open source and gratis and the community is really competent.
