Which service allows for serverless event-driven computing?

The service that enables serverless event-driven computing is Google Cloud Functions. This service is designed to execute code in response to various events, such as HTTP requests or changes in data storage, without the need to manage servers or infrastructure.

With Google Cloud Functions, developers can deploy functions that automatically scale depending on the number of events they receive. This means you pay only for the computing resources your functions consume when they are triggered, making it a cost-effective solution for handling sporadic workloads. The event-driven nature allows for quick and efficient response to events from other Google Cloud services or external sources.

While Google App Engine also offers a platform for building and deploying applications, it does not focus solely on event-driven execution in the same manner as Cloud Functions. Google Kubernetes Engine is a container orchestration service that requires managing clusters of servers, which diverges from the serverless paradigm. Google Cloud Dataflow is primarily used for data processing and analytics, allowing for complex data pipelines but does not fit the criteria for serverless event-driven computing as closely as Cloud Functions does.
