IBM Cloud Functions is a software platform that provides provides identity and access management (IAM) capabilities for serverless apps running in the IBM Cloud. Cloud Functions software is based off of Apache OpenWhisk.
Rather than charging the customer for reserved capacity, Cloud Functions uses a Function as a Service (FaaS) business model. The platform is designed to allow lightweight code to run app logic written in any programming language to respond to HTTP-based application program interface (API) requests. Cloud Functions is well suited for microservice development projects and event-based data processing.
IBM Cloud Function stateless code snippets are referred to as actions and each action is designed to perform a singular task. A series of actions allows developers to create serverless sequences that will execute in real time in response to a specific event. The Cloud Function platform includes the following products and services:
