What are the main types of Google Cloud Functions?
HTTP Functions: These functions handle HTTP requests and use HTTP triggers. You can implement functions that respond to specific web requests. For example, processing an API request or generating a custom response for a specific URL.
Event-bas functions: These functions handle events within your cloud environment. They use event triggers to respond to changes in services like Cloud Storage, Firestore, Pub/Sub, and more. For example, you can run a function when a file is upload to Cloud Storage or when a new document is add to Firestore.
What development possibilities does Cloud Functions offer?
Cloud Functions is a highly versatile tool, which is why we use it at IKAUE, in addition to other reasons already mention. This tool allows you to:
Task automation: You can create functions to automate repetitive processes. For example, notifying users when a product is updat in your online store or processing data in real time.
Image Processing: Use Cloud Functions to automatically resize images when they are upload to your app. This is useful for creating thumbnails or adapting images to different devices.
Integration with external APIs: Connect your functions to external services, such as sending messages through Slack, Twilio, or SendGrid. For example, you can receive notifications of errors in your app and send alerts to a Slack channel.
Webhooks: Create HTTP endpoints that are trigger in response to specific events. For example, receiving notifications of changes to a database or message queue.
Firebase Event Processing: If you use Firebase, you can leverage Cloud Functions to process events such as user authentication, database changes, or sending push notifications.
Validation and Security: Implement functions to validate data before saving it to a database or to authorize API requests.
Auto-scaling: Cloud Functions automatically scale bas on demand, making them ideal for applications with peak traffic.
