- IAM enablement
- Namespaces can now be explicitly managed and show up on the dashboard
- Manage Namespace Settings
Run your application code without servers, scale it automatically, and pay nothing when it's not in use.
What's New:
- Updated action runtimes
- Increased maximum memory for actions to 2048MB.
- Added support for monitoring the performance of your actions using metrics.
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.
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.
Go to tutorialMobile 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.
Go to tutorialCase-Study: Weather Gods Fire, Ice, Water, Air & Moon delivering you the weather as you have never experienced it before.
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.
Case-Study: With Skylink, a drone is continuously taking and analyzing pictures while flying using an IBM Watson service.
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 Event Streams—an IBM Cloud managed Apache Kafka—integration.
Check Out a Sample AppConversational Scenarios
Implement serverless conversational applications, like chatbots, by passing chat messages to your functions for further processing.
Go to tutorialScheduled Tasks
Execute your functions periodically. Define schedules following a cron-like syntax to specify when actions are supposed to be executed.
