 Function as a Service (FaaS) is a [cloud computing](/cloud-computing/) model that provides a platform for executing event-triggered functions, allowing for automatic scaling without manual intervention.
 At its essence, FaaS enables the deployment of individual functions that are activated by specific events, operate on a short-term basis, and then shut down, ensuring resources are not wasted.
 This model supports an [autoscaling](/auto-scaling/) feature, enabling a function instance to be initiated per request and terminated post-execution, emphasizing its [stateless](/stateless-apps/) nature.
-Consequently, FaaS platforms can implement a true pay-as-you-go billing approach, eliminating costs when functions are dormant, distinguishing it from other models like [Platform as a Service (PaaS)](/platform-as-a-service/), which require continuous resource availability.
