What is an ideal use case for deploying Cloud Functions?

Deploying Cloud Functions is particularly well-suited for light-weight, event-driven, serverless, and microservices architecture. This is because Cloud Functions allows developers to write single-purpose functions that respond to events, such as HTTP requests or changes in data, without the overhead of managing server infrastructure.

The serverless nature of Cloud Functions means that developers can focus on writing code and implementing functionality without having to worry about the underlying servers or runtimes. Its microservices capability aligns well with modern application design, where each function can be a standalone service that performs a specific task, thus enabling efficient scaling and resource management.

Using Cloud Functions is ideal for scenarios such as responding to file uploads in Cloud Storage, processing messages from a Pub/Sub topic, or triggering workflows in response to changes in a database. Such use cases benefit from the scalability and reduced operational burden that Cloud Functions provide, allowing developers to deliver efficient and responsive applications quickly.

In contrast, the other options refer to scenarios that could require more complex setup and management, which diverges from the intended purpose of Cloud Functions.
