Google Cloud Functions
Google Cloud Functions is a lightweight, event-based, asynchronous compute solution that allows you to create small, single-purpose functions that respond to cloud events.
Key Features
- Serverless: No servers to provision, manage, or upgrade.
- Event-Driven: Responds to events from Cloud Storage, Pub/Sub, HTTP, etc.
- Scalable: Scales automatically from zero to thousands of functions.
Use Cases
- Data Processing: Process files as they are uploaded to Cloud Storage.
- Webhooks: Implement webhooks for third-party integrations.
- Lightweight APIs: Build simple microservices.
Key Concepts
- Triggers: The event that invokes the function (HTTP, Background).
- Runtimes: Supported languages (Node.js, Python, Go, Java, .NET, Ruby, PHP).
- Gen 2: Built on Cloud Run, offering longer timeouts and larger instances.
