Primitives & Concepts

The core building blocks of iii-powered applications.

iii is built around three core concepts: Function, Trigger, and Worker.

We recommend learning the primitives and concepts behind iii before going deeper. But if you prefer to get started building then go to the How to use Functions and Triggers guide. Or if you want to learn about the deeper aspects of iii's architecture then go to the Architecture section.

Every worker sees every function in the system — and gets notified when functions appear or disappear as workers connect and disconnect.
