Welcome to cloud computing, where software is cattle, not pets.
There isn't a Linux server taking care of a couple of services.
There are services deployed as Kubernetes pods, or serverless language runtimes across a cluster abstraction, running directly on top of type 1 hypervisors, or minimal kernel images enough to power distroless container images.
Let me know when your local OS does multi-machine scheduling across heterogeneous hardware and application constraints, networking, observability, service accounts and a finer grained permissions system, in a way that’s far less confusing and piecemeal.
Also, this argument only works if you just broaden the definition of “OS” to “anything that runs that isn’t your apps”.
