Re: Has virtualization become obsolete in 5G?

[Mel Beckman <mel () beckman org>]

An operating system is just a high-level machine. That the M-plane in VM is implemented in software isn’t relevant, as 
pretty much all hardware CPUs are implemented in software as well, so VM is just virtualizing software already.

Containerization is VM, but using the OS as the M-plane As long as the OS delivers all the functions needed by 
applications, it’s a perfectly reasonable, and even preferable, plane to virtualize.

That pretty much sums up Intel's view.

To quote an Intel executive I was corresponding with:

"The purpose of the paper was to showcase how Communication Service Providers can move to a more nimble and future 
proof microservices based network architecture with cloud native functions, via container deployment methodologies 
versus virtual machines.  The paper cites many benefits of moving to a microservices architecture beyond whether it is 
done in a VM environment or cloud native. We believe the 5G networks of the future will benefit greatly by implementing 
such an approach to deploying new services."

The paper referred to is this 
one<https://www.intel.in/content/www/in/en/communications/why-containers-and-cloud-native-functions-paper.html>.

Would anyone care to let me know his thoughts on this prediction?

Virtualization is not becoming obsolete ... quite reverse in fact in all types of deployments I can see around.

The point is that VM provides hardware virtualization while kubernetes with containers virtualize OS apps and services 
are running on in isolation.

Clearly to virtualize operating systems as long as your level of virtualization mainly in terms of security and 
resource consumption isolation & reservation is satisfactory is a much better and lighter option.

Thx,
