Filter as a Service (FaaS) is a cloud computing model that allows developers to build and run applications without managing the underlying infrastructure. In this model, cloud providers dynamically manage the allocation and provisioning of servers. Developers write and deploy code in small, discrete units called functions, which are triggered by events. These events can be anything from an HTTP request, a database change, to a file upload.

When an event occurs, the cloud provider automatically spins up the necessary resources to execute the function. Once the function has completed its execution, the resources are released. This pay-as-you-go pricing model means users are only charged for the compute time they consume, making it highly cost-effective for many applications, especially those with variable or infrequent workloads. FaaS abstracts away the complexities of server maintenance, scaling, and patching, allowing developers to focus solely on writing business logic. Common use cases include building APIs, data processing pipelines, real-time file processing, and powering IoT devices. Major cloud providers like Amazon Web Services (AWS Lambda), Microsoft Azure (Azure Functions), and Google Cloud Platform (Cloud Functions) offer FaaS solutions.
