Unikernel is - in short - an attempt to even more isolate an application and its libraries (and bind them together in a single binary). However it's pretty hard to setup and prepare, and therefore didn't gain massive adoption. I don't know if a XEN Unikernel such as MirageOS or Rump would construct it can provide even better performance than OS-level virtualization, but I suppose it was part of the goal. -- Pierre-Philipp Braun SMTP Health Campaign: enforce STARTTLS and verify MX certificates <https://nethence.com/smtp/> ^ permalink raw reply [flat|nested] 5+ messages in thread
