Why Oracle Cloud Free Tier?

Oracle Cloud's Always Free tier includes:

• 4 ARM Ampere A1 cores (total)
• 24 GB RAM (total)
• 200 GB block storage
• 10 TB/month outbound data
• No credit card expiration — truly free forever

This is enough to run a production NestJS backend, PostgreSQL (via Supabase), and Redis for thousands of daily active users.

The Setup Problem

First-time Oracle Cloud setup takes 4-8 hours:

• Create Oracle Cloud account and configure compartment
• Provision ARM instance with Ubuntu
• Configure security lists (firewall rules)
• Install Docker and Docker Compose
• Set up SSH access and keys
• Configure GitHub Actions for automated deployment
• Set up SSL/TLS with Let's Encrypt

How AI App Factory Handles It

• Docker Compose configured for NestJS + Redis
• GitHub Actions workflow for build → push → deploy
• SSH deployment script included
• Environment variable management via GitHub Secrets
• Health check endpoint for monitoring

Architecture

GitHub Push → GitHub Actions → Docker Build → SSH Deploy → Oracle Cloud

                                                    NestJS + Redis
                                                    (ARM, 24GB RAM)
