In the context of cloud computing, what does FaaS stand for?

Function as a Service (FaaS) is a cloud computing service model that allows users to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching microservices and serverless applications. In this model, developers can write code in response to events, and the cloud provider manages the server resources required to execute that code.

FaaS enables developers to focus purely on writing functions, which are small, single-purpose pieces of code that are executed in response to triggers, such as API calls or changes in data. This helps in enhancing scalability, as the functions can be executed in parallel without needing to manage server instances manually. Additionally, it offers a cost-efficient way to run applications, as billing is typically based on the number of executions and the duration of the execution, rather than pre-allocating server capacity.

Options referring to frameworks, facilities, or files do not accurately capture the serverless architecture and execution model that is integral to FaaS, therefore making those choices less aligned with the established terminology in cloud computing.
