What is serverless applications?

Serverless applications are a cloud computing execution model where the cloud provider dynamically manages the allocation of machine resources. Instead of provisioning and managing servers, developers deploy code, typically in the form of functions, and the cloud provider executes the code in response to triggers (e.g., HTTP requests, database updates, scheduled events). Users are typically charged based on the actual consumption of resources, rather than a pre-purchased amount of capacity, which can lead to cost savings. Serverless architectures allow developers to focus on writing code without worrying about server management, scaling, or infrastructure maintenance.
