Unless you’re in Erlang world (Elixir, Gleam..) and all that is already baked into OTP and the BEAM. You can go on holiday knowing it will be a while longer before you need to break out the pods (and at that scale, you will be able to afford a colleague or two to help you).

How does Elixir renew my certificates, mount networked storage mounts and create a VIP and internal DNS entries for my valkey instance?

Scaling is a sidenote, that it becomes easy is a result of hoisting everything else onto one control plane and a set of coherent APIs.
