Cloud Functions
Cloud Functions is a serverless compute service that allows developers to run event-driven code without provisioning or managing servers. It automatically scales in response to events and executes functions in response to triggers from various cloud services or HTTP requests. This enables building lightweight, scalable applications and microservices with minimal operational overhead.
Developers should use Cloud Functions for building event-driven architectures, automating workflows, and creating microservices that respond to real-time events like file uploads, database changes, or message queue updates. It's ideal for scenarios requiring rapid scaling, cost efficiency (pay-per-use pricing), and simplified deployment, such as data processing pipelines, webhooks, and IoT backends.
