With serverless, the cloud provider abstracts away the servers, runtimes, scaling, and capacity planning from the developer. The developer focuses on the application code and business logic, while the cloud provider handles provisioning servers, auto-scaling, monitoring, etc., under the hood.

But from the developer’s perspective, there are no visible servers to manage. The cloud provider handles the servers, operating systems, and runtimes.
