OCI Functions and Serverless

OCI Functions is a serverless compute platform that lets you run code without managing infrastructure. Built on the open-source Fn Project, OCI Functions provides a standards-based, event-driven compute service.

What is OCI Functions?

OCI Functions lets you:

• Write small, focused pieces of code (functions)
• Deploy them without provisioning servers
• Pay only for the time your code executes
• Scale automatically from zero to thousands of concurrent executions

OCI Functions is based on the Fn Project, an open-source, container-native serverless platform.

How OCI Functions Works

1. You write a function in a supported language
2. The function is packaged as a Docker container
3. You deploy it to an application (a logical grouping of functions)
4. When invoked, OCI provisions the container, runs your code, and returns the result
