What do containers have to do with microkernels?
If we're talking about BSD jails, Solaris/Illumos zones, and Linux cgroups + namespaces, there are basically two scenarios: Either multi-tenancy is handled through hardware virtualization (mainstream cloud providers), or all of the containers are run on a shared monolithic kernel (Joyent's Triton, running Linux binaries in containers via LX-branded zones on Illumos). I suppose the former scenario could be seen as a vindication of microkernels, if you consider the Xen hypervisor a microkernel. But that has nothing to do with containers.

- vertex-four 10y agoContainers are not VMs.
- SwellJoe 10y agoBut, they can be (and are) used in similar ways. I think it's reasonable to talk about VMs and containers in the same conversation.
- vertex-four 10y agoSure, but the conversation brought up microkernels in relation to containers specifically - which is nonsensical.
