Key features

Key features

Simplified developer experience and increased developer velocity

Cloud Run functions has a simple and intuitive developer experience. Just write your code and let Google Cloud handle the operational infrastructure. Develop faster by writing and running small code snippets that respond to events. Streamline challenging orchestration problems by connecting Google Cloud products to one another or third-party services using events.

Pay only for what you use

You are only billed for your function’s execution time, metered to the nearest 100 milliseconds. You pay nothing when your function is idle. Cloud Run functions automatically spins up and backs down in response to events.

Avoid lock-in with open technology

Use open source FaaS (function as a service) framework to run functions across multiple environments and prevent lock-in. Supported environments include Cloud Run, local development environment, on-premises, and other Knative-based serverless environments.

Use cases

Use cases

Use case
Integration with third-party services and APIs

Use Cloud Run functions to surface your own microservices via HTTP APIs or integrate with third-party services that offer webhook integrations to quickly extend your application with powerful capabilities, such as sending a confirmation email after a successful Stripe payment or responding to Twilio text message events.

Integration with third party services workflow diagram: Box on left reads Push commits. Arrow leads right to GitHub box, another arrow, labeled GitHub push webhook, leads right to Cloud Functions. Arrow labeled Slack postMessage API leads right to Slack box
Use case
Serverless mobile backends

Use Cloud Run functions directly from Firebase to extend your application functionality without spinning up a server. Run your code in response to user actions, analytics, and authentication events to keep your users engaged with event-based notifications and offload CPU- and networking-intensive tasks to Google Cloud.

Serverless mobile back ends workflow diagram: From left to right: icon labeled New follower flows to Database icon, to Cloud Functions icon, to Firebase Cloud Messaging icon, and to New message icon
Use case
Serverless IoT backends

Use Cloud Run functions fully managed services to build backends for Internet of Things (IoT) device telemetry data collection, real-time processing, and analysis. Cloud Run functions allows you to apply custom logic to each event as it arrives.


From left to right, icon labeled “Sensor/temperature reached 80℉ flows right to Cloud IoT Core icon, to Pub/Sub icon, to Cloud Functions / Trigger configuration change, to Cloud IoT Core, to Ceiling fan / turn on
Use case
Real-time file processing

Execute your code in response to changes in data. Cloud Run functions can respond to events from Google Cloud services, such as Cloud Storage, Pub/Sub, and Cloud Firestore to process files immediately after upload and generate thumbnails from image uploads, process logs, validate content, transcode videos, validate, aggregate, and filter data in real time.

From left to right: Storage icon flows through arrow labeled Function triggered to Cloud Functions / Processes uploaded image, to Cloud Vision API / Detects offensive images, to Cloud Functions / Blurs images using ImageMagick, to Storage
Use case
Real-time stream processing

Use Cloud Run functions to respond to events from Pub/Sub to process, transform, and enrich streaming data in transaction processing, click-stream analysis, application activity tracking, IoT device telemetry, social media analysis, and other types of applications.

From left to right: Storage icon flows through arrow labeled Function triggered to Cloud Functions / Processes uploaded image, to Cloud Vision API / Detects offensive images, to Cloud Functions / Blurs images using ImageMagick, to Storage
Use case
Virtual assistants and conversational experiences

Easily build artificial intelligence into your applications. Cloud Run functions with Cloud Speech API and Dialogflow can extend your products and services with voice- and text-based natural conversational experiences that help users get things done. Connect with users on Google Assistant, Amazon Alexa, Facebook Messenger, and other popular platforms and devices.

Workflow from left to right. 3 boxes, labeled Slack, Messenger, and Google Home flow to Dialogflow icon, then to Cloud Functions icon, then branch to flow to AI Platform and Vision API icons at top, and Datastore icon at bottom.
Use case
Video and image analysis

Use Cloud Run functions with Video Intelligence API and Cloud Vision API to retrieve relevant information from videos and images, enabling you to search, discover, and derive insight from your media content.

Workflow moves from left to right: A blue box with right-facing white triangle (“Play”) flows to Cloud Storage / (Full-length video) icon. Flow branches up to Front end built on App Engine and down to Cloud Functions then Video Intelligence. Flow moves along lower path with arrow labeled “Video Metadata” to icon labeled Cloud Storage / (Video annotation JSON). Flow then moves up and left back to Front end build on App Engine.
Use case
Sentiment analysis

Use Cloud Run functions in combination with Cloud Natural Language API to reveal the structure and meaning of text and add powerful sentiment analysis and intent extraction capabilities to your applications.

Sentiment analysis workflow diagram: Starting on left, icon labeled Text Message has speech bubble on top: “Devoxx is such an amazing event!” Solid arrow leads right to box labeled Twilio, from which dashed arrow leads left to the Text message. From Twilio, solid arrow leads right to Cloud Functions icon, from which dashed arrow leads left to Twilio. From Cloud Functions, bi-directional arrows lead to Natural Language API / Sentiment extraction icon and to BigQuery/Trend analysis icon
