Do you know why "Kubernetes on Baremetal" is important for Telcos?

Because you cannot deploy any media (data plane) functions on “K8s hosted on the cloud” i.e. worker nodes running as VMs.

Media functions are nothing but high-performance routers.
Examples of media or dataplane functions are -

𝗜𝗻 𝟰𝗚 - SBC, SGW, PGW, CGNAT, etc.
𝗜𝗻 𝟱𝗚 - UPF (User plane function).

All these data plane VNFs/CNFs require SRIOV (bypassing the hypervisor of the host server) for a telco-grade performance which you cannot achieve if your worker nodes are working as VMs on top of a cloud environment.

Rest all VNFs/CNFs are majorly signaling nodes & can be deployed either on cloud or on Baremetal also.
