vEPC using containers

Can someone please put a limelight for vEPC using containers if have used it - how is it different from virtualized VNFs of core launched as using till now used openstack/VM ware platforms or can share article/document to understand container based cloud packet core?

I have not heard about Core but RAN is deployment is happening in Containers.
Anyway either it RAN or core - all are VNFs.

Do you have Huawei support account? There is an amazing document series explain all 5G core principles regardless of vender
