# Oracle Cloud Reference Architecture
## Overview
OCI architecture has more moving parts than AWS or Azure. Where AWS has VPC + subnets + internet gateway, OCI has VCN + regional subnets + Internet Gateway + NAT Gateway + Service Gateway + DRG (Dynamic Routing Gateway) + LPG (Local Peering Gateway) — and getting the routing tables wrong means silent packet drops with no error. This provides the standard 3-tier architecture (web/app/db) with every OCI-specific component wired correctly, plus Terraform code to deploy it.
**Purpose:** Produce a production-ready 3-tier OCI architecture with correctly configured networking, gateways, security rules, and compute/database tiers — deployable via Terraform.
## Prerequisites
- **OCI account** with an active tenancy — https://cloud.oracle.com
- **OCI CLI installed and configured** — `~/.oci/config` validated (see `oraclecloud-install-auth`)
- **Python 3.8+** with the OCI SDK — `pip install oci`
- **Terraform 1.5+** with the OCI provider — https://registry.terraform.io/providers/oracle/oci/latest/docs
- **Compartment OCID** for the target environment
