Google Cloud Run Functions Cheat Sheet

• A pay-as-you-go function as a service (FaaS) to run your code with zero server management.

Features

• There is no need to provision, manage, or upgrade servers.
• Cloud Run Functions can be written using:
  • Node.js
  • Python 3
  • Go
  • Java
• Automatically scales based on load without thinking about the infrastructure.
• Built-in security at role and per function level based on the least privilege principle.
• Allows you to trigger your code from Google Cloud, Firebase, and Google Assistant or call it directly from any web, mobile, or backend application via HTTP.
• To act on events, you shall define a trigger. Binding a function to a trigger enables you to act on events. The most common triggers are:
  • Google Cloud Storage 
  • Supported HTTP request types like: POST, PUT, GET, DELETE, and OPTIONS.
  • Pub/Sub

• All customers get 2 million invocations, 400,000 GB-seconds, and 200,000 GHz-seconds of compute time free per month.
• Use open-source FaaS framework to run functions across multiple environments (Cloud Run, local, on-premises, other Knative-based platforms) to prevent vendor lock-in.
• Integrated monitoring with Cloud Trace, Cloud Monitoring, and Cloud Logging for full diagnosability.
• Respond to events from: Cloud Firestore, Cloud IoT Core, Dialogflow, and third-party webhooks (Stripe, Twilio).

Use Cases

• Integration with third-party services: Send confirmation emails after Stripe payments or respond to Twilio text messages.
• Serverless mobile backends: Extend Firebase apps with event-driven notifications.
• Serverless IoT backends: Process IoT device telemetry data in real-time.
• Real-time file processing: Generate thumbnails, transcode videos, validate content upon upload to Cloud Storage.
• Real-time stream processing: Enrich streaming data from Pub/Sub for analytics.
• Virtual assistants: Build conversational experiences with Dialogflow and Cloud Speech API.
• Video and image analysis: Use Vision API and Video Intelligence API to derive insights from media.
• Sentiment analysis: Combine with Natural Language API to analyze text.

Pricing

• Priced based on:
  • Invocation count (2 million free per month)
  • Compute time (400,000 GB-seconds free per month)
  • CPU time (200,000 GHz-seconds free per month)
  • Outbound data transfer (5 GiB free per month)
• Billed in 100-millisecond increments. No charges when function is idle.
• Outbound data to Google APIs in same region and inbound data transfer are always free.
