Which Function as a Service does Google provide?

Google Cloud Functions is the correct answer because it is Google's official platform for Function as a Service (FaaS) that allows users to run code in response to events without the need to manage servers. This service enables developers to write single-purpose functions that are triggered by various events, such as HTTP requests, changes in Cloud Storage, or messages received from Pub/Sub.

By using Cloud Functions, developers can focus on writing specific units of logic while Google manages the underlying infrastructure, scaling, and maintenance. This fits seamlessly into the serverless architecture, enabling efficient deployment of applications without the complexity of running servers.

The other provided options, such as Google Lambda and Google Functions, do not represent recognized services offered by Google. Google Serverless Functions is also not the official terminology used by Google, making them incorrect choices when identifying the specific service provided by Google for Function as a Service.
