Hypervisor and virtualization benefits

“

(upbeat music) - [Instructor] So far, we have talked about the virtualization and how it helps us run multiple network functions on shared hardware. But how exactly do we go from physical hardware to the virtual machines? And the answer lies in the powerful piece of software, which is called Hypervisor. So imagine you have a physical server with 8GB of RAM, you have CPUs, and you have certain storage and networking interfaces. Now, Hypervisor is the software layer that sits between the hardware and the virtual machines. It takes these physical resources and slices them into virtual components and how it works. For example, let's say you want to run three different applications. You have a 5G core network, you have application one, which is virtual machine one, maybe belonging to AMF in that case, which needs 2GB of RAM. So it will be allocated with the 2GB of RAM for this particular application of AMF. We then have another virtual machine for certain other application, maybe for UPF…
