Definition
Serverless architecture allows developers to build and run applications without managing server infrastructure. The cloud provider automatically scales resources up or down based on demand, charging users only for the compute time they consume. While servers still exist, their management is abstracted away. This model supports event-driven computing, enabling functions to trigger automatically in response to specific events, such as database changes or HTTP requests, reducing operational overhead significantly.
Summary
A cloud computing execution model where the provider dynamically manages the allocation of machine resources instead of the user.
