        Getting Started with IBM Cloud Functions

        IBM Cloud Functions (based on Apache OpenWhisk) is a Function-as-a-Service (FaaS) platform which executes functions in response to incoming events and costs nothing when not in use.Learn more

        New on GitHub:

        Try Composer for IBM Cloud Functions: build complex applications and workflows, 100% serverless. Available now as a Tech Preview from IBM Research.

        Save costs, scale and integrate.

        Cost-Effective Computing

        Pay for what time you use down to one-tenth of a second.

        Automatically Scale

        Run your action thousands of times in a fraction of a second, or once a week. Action instances scale to meet demand exactly, then disappear.

        Easy Integration

        Trigger your actions from events in your favorite services, or directly via REST API.

        Runtimes

        Work with what you already know and love. Develop your functions directly in your favorite language, or provide us with a Docker container to develop using any compiled language such as Go or C.

        Event Providers

        Benefit from an ecosystem of event consumers and emitters from different areas like analytics, cognitive, data, IoT, mobile, and more. Using our open event-provider interface, you can enable any service you would like to use.

        What would I use Cloud Functions for?

        Serverless Backends

        Expose application logic by implementing serverless microservices. Simply map your functions to well-defined API endpoints any client can call by making use of Web Actions or our latest API Gateway integration.

        Mobile Backend

        Allow mobile developers to easily access server-side logic and to outsource compute-intensive tasks to a scalable cloud platform. Let them implement functions in languages like Swift and easily consume server-side functions using our iOS SDK.

        Data Processing

        Execute code whenever data is updated in your datastore. Easily automate processes like audio normalization, image rotation, sharpening, noise reduction, thumbnail generation, or video transcoding.

        Cognitive Data Processing

        Analyze data as soon as it becomes available. Let your function make use of powerful cognitive services like IBM Watson to detect objects or people appearing in images or videos.

        IoT Ready

        React to and process IoT sensor data. Let any IoT device send data to our IBM Watson IoT platform and define cloud rules to call your functions and execute custom application logic.

        Event Stream Processing

        Process data in-motion and make your functions react to incoming messages. Benefit from our IBM Cloud Message Hub—an IBM Cloud managed Apache Kafka—integration.

        Conversational Scenarios

        Implement serverless conversational applications, like chatbots, by passing chat messages to your functions for further processing.

        Scheduled Tasks

        Execute your functions periodically. Define schedules following a cron-like syntax to specify when actions are supposed to be executed.
