Serverless computing is a cloud computing execution model where the cloud provider dynamically manages the allocation and provisioning of servers. In this model, developers can build and run applications without having to manage the underlying infrastructure. Instead, they focus on writing code, and the cloud provider handles the execution, scaling, and maintenance of the backend services on an as-used basis.

A. A computing method of providing backend services on an as-used basis. Serverless computing is a cloud computing model in which the cloud provider automatically manages the infrastructure and dynamically allocates resources as needed. Developers can focus on writing code without worrying about server management, and they are only charged for the actual usage of resources rather than pre-provisioned capacity.
