OCI Serverless Functions with Terraform (2024 Edition)

Master Serverless Architecture with Our OCI Serverless Functions Course

This OCI Serverless Functions course is a deep-dive, hands-on experience built entirely around real Terraform code and automation scenarios. It teaches you to build scalable, secure, and production-ready serverless applications on Oracle Cloud Infrastructure (OCI), with a strong emphasis on modular infrastructure using Terraform.

You'll also explore function orchestration, asynchronous processing, and security patterns like JWT token validation. Whether you're integrating real-time IoT data pipelines or triggering functions via Object Storage events, this course equips you with everything needed to confidently build production-grade OCI serverless solutions with Terraform.

You will work directly with a public GitHub repository that includes real-world Terraform modules for OCI Functions, API Gateway, Streaming, and Autonomous Database (ADB-S).

🔧 What You’ll Build in This Course

✅ Lesson 1: Hello World Function

Create your first OCI Function (fkfn) using the terraform-oci-fk-module. You’ll set up a complete VCN, subnet, security lists, and expose your function via OCI Container Registry. Everything is automated and invoked from Terraform.

✅ Lesson 2: Custom Python Function

Define a new function (fncustom) from scratch with Dockerfile, Python source (func.py), manifest (func.yaml), and requirements.txt. You’ll inject a custom environment variable and invoke the function via Terraform.

✅ Lesson 3: Two Functions, One Application

Create fncustom1 and fncustom2 under the same OCI Application, managing shared networking. You’ll reuse Terraform modules and outputs to inject the shared Application OCID. Both functions are deployed and triggered via Terraform.

✅ Lesson 4: Functions Behind API Gateway

Deploy fncustom1 and fncustom2 in a private subnet and expose them securely via API Gateway. You’ll add IAM policies to authorize Gateway access, simulate real-world production exposure, and unify endpoints.

✅ Lesson 5: Functions with OCI Notification Service (ONS)

Create fninitiator and fncollector to simulate asynchronous processing. You’ll trigger fninitiator via API Gateway, which pushes a message to ONS. The subscribed fncollector reacts automatically – showcasing event-driven architecture.

✅ Lesson 6: Streaming + ADB-S Integration

Add OCI Streaming and Autonomous Database Serverless (ADB-S) to your architecture. Messages go from fninitiator to both ONS and Streaming. The fncollector reads from the stream and inserts records into IOT_TABLE. You’ll also deploy fnadbsetup to prepare the database and user.

✅ Lesson 7: Service Connector Hub (SCH)

Swap ONS for OCI Service Connector Hub, connecting Streaming to fncollector directly. This reduces complexity, improves observability, and decouples your processing logic. Learn how to automate connector creation via Terraform.

✅ Lesson 8: JWT Authentication

Introduce a new function fnjwtauth to validate JSON Web Tokens in the API Gateway. You’ll secure fninitiator so only requests with valid JWT tokens are accepted. The API Gateway policy and deployment will enforce this in production.

✅ Lesson 9: Bulk Upload via Object Storage and Events

Automate file-driven data ingestion with OCI Event Service and Object Storage. The fnbulkload function is triggered when a JSON file (e.g., devices.json) is uploaded. Records are parsed and injected into the stream, then routed to ADB-S by fncollector.
