FaaS (Function as a Service)

FaaS, or Function as a Service, is a cloud computing model that allows developers to run specific pieces of code—called functions—without managing servers. When an event triggers the function, the cloud provider automatically executes it, scaling resources as needed. This approach enables efficient, cost-effective, and flexible software development, as users pay only for the compute time they consume. FaaS is ideal for tasks like processing data, responding to user actions, or automating workflows, allowing developers to focus on writing code rather than infrastructure management.
