Has virtualization become obsolete in 5G?

Tue Aug 4 15:38:06 UTC 2020

Wondering whether the industry will consider containerised data-plane in addition to control-plane (like cRDP). 

Having just control-plane and then hacking to kernel for doing the data-plane bit is …well not as straight forward as having a dedicated data-plane VM or potentially container.

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.  

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%20> .

Cheers,

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,
