LLMs can now quite trivially write Terraform or Ansible code to setup infra, maybe harder for non-engineers to make those prompts for now. But ongoing maintenance and monitoring would require an online agent evaluating signals and deciding when to take what action or prompt the user. Like autoscaling decesions can be already automated and some failover/recovery for simple cases. Probably people releasing hobby projects do not need too much. And then there are things like exe.dev to wrap that and make it simply to give an execution env instead of you and your agent managing your own infra.
