Server VS Serverless, VM's In Serverless Architecture [DevOps Low Down] 

Now your video has confused me because a VPS is a VM shared between a few people. Shared hosting as far as I know also can be on a VM. As far as I know from Google Cloud serverless like cloud functions are serverless because the company manages the VM cluster e.g. with Kubernetes and Docker containers and load balancing for you. On the other hand with a VPS or dedicated server you have a limited VM without load balancing or as a cluster of VMs or containers. Am I missing something here?
