INTRODUCTION

• Oracle Functions in Oracle Cloud Infrastructure
  (OCI) is a serverless, event-driven compute
  service that lets you run code without
  provisioning.
• Managing servers Its built on the open-source Fn
  Project, which makes it portable and easy to
  integrate with other cloud or on-premises
  environments.

What is Oracle Functions?

• Oracle Functions is a serverless compute service
  provided by Oracle Cloud Infrastructure (OCI)
  that allows you to run code without having to
  manage servers or infrastructure. It's designed
  to execute small, single-purpose functions in
  response to events, HTTP requests, or on-demand.

How It Works

• Trigger the Function

• Deploy to OCI

• Manually via Fn CLI or REST API.
• Automatically by OCI Events Service (e.g., object
  uploaded, instance stopped).
• Through an API Gateway (like a REST endpoint).
• Scheduled with OCI's Resource Scheduler or other
  services.

• Build the function (turns code into a Docker
  image).
• Push the image to OCI Container Registry.
• Deploy the function to Oracle Functions, which
  stores and manages it.

Supported Languages

• Since Oracle Functions runs your code in Docker
  containers, any language can be used as long as
• You can build a Docker image.
• The function listens for input via stdin and
  responds via stdout.
• This gives you full flexibility want to use
  Rust, PHP, or .NET? Just package it properly in a
  container.

Key Features

• Serverless Fully Managed
• No need to provision, scale, or manage
  infrastructure.
• OCI handles everything behind the scenes
  servers, patching, availability, etc.
• Focus purely on your code and logic.

• Based on Open Source Fn Project
• Uses the Fn Project, an open-source serverless
  platform.
• Portable Functions can run locally, on-prem, or
  in other clouds.
• Developer-friendly CLI tools and local testing
  environment.

Integration with OCI Services
One of the biggest strengths of Oracle Functions
is its tight integration with other OCI services,
making it easy to build event-driven,
cloud-native applications. Here's a rundown of
how Oracle Functions integrates across the OCI
ecosystem

• OCI Events Service
• Trigger functions automatically when events
  occur in OCI.
• Examples
• Object uploaded to Object Storage
• Compute instance created/stopped
• Database backup completed

Security Features
Oracle Functions provides several built-in
security features to ensure your serverless
applications are secure, isolated, and compliant
with best practices. Here are the key security
features of Oracle Functions

• Isolation with Containers
• Each function runs in its own isolated Docker
  container, providing security at the runtime
  level.
• This isolation helps prevent unauthorized access
  between functions.
• Functions dont share resources (e.g., memory,
  CPU) with other functions.

Summary Conclusion

• Oracle Functions is a serverless compute service
  on Oracle Cloud Infrastructure (OCI) that allows
  developers to build, deploy, and run event-driven
  applications without managing servers. Its based
  on the Fn Project, which makes it portable and
  open-source. Heres a recap of its key features
  and benefits

• Security Highlights
• Isolation Each function runs in an isolated
  Docker container, ensuring no resource sharing.
• IAM Integration Fine-grained control over who
  can access and invoke your functions.
• Secrets Management Integrates with OCI Vault for
  secure handling of credentials and secrets.
