Well, if you're deploying in a container where the only useful userspace program is your http server web API, embedding the whole clib and cpplib just for a few functions, it is smaller and simpler to deploy to use static linking.

Aye, a container with the binary and the right versions of the supporting libraries is essentially static linking with extra steps.

Containers offer some tooling for resource management and such, though that is basically wrappers and other syntactic sugar dressing up OS facilities like resource groups so isn't anything you can't do with a statically linked binary too.
