You end up needing a whole new team to do HA/scaling for a core service. It's not limited to some. You absolutely need a whole new team (or teams) to handle your infrastructure, your high availability needs, and also your security. The nifty serverless offerings and other features are just nice-to-haves in comparison to the core infrastructure work that cloud providers put into your system to keep it running. Just because cloud providers like GCP and AWS and Azure and etc have everything put together to let you setup your whole infra by running a small script that does not mean nothing needs to be done in order for that to work.
