Xen and Microservices.
Hello,
Why microservices use containers like Docker and not Hypervisors like Xen?

Thanks.

Jason,
containers, like Docker and kubernetes are designed to let you
sandbox/isolate one application or one service... without having to also
host an operating system for each container.

Hypervisors like XEN are designed for operating systems, not single
applications.

Hope this helps

Thank you.
How about Unikernel?

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.

Thanks.
Thus, Unikernel is something like Microservice? Any success?
