Oracle Cloud Infrastructure (OCI) offers without question the most generous "Always Free" tier in the cloud computing industry.
While AWS and Google Cloud offer 12-month trials or tiny f1-micro instances, Oracle provides high-performance Ampere A1 ARM compute resources that remain free indefinitely.
What You Get for Free
- 4 OCPU Ampere ARM Compute Cores: Can be allocated as a single 4-core machine or up to 4 separate instances.
- 24 GB of RAM: Massive memory overhead sufficient for running Docker containers, databases, and microservices.
- 200 GB of Block Storage: High-speed NVMe block storage with flexible automated boot volume backups.
- 10 TB of Monthly Outbound Data Transfer: Perfect for serving APIs and web applications.
Best Practices for Always Free Architecture
1. Pair with Cloudflare: Place Cloudflare DNS and Edge caching in front of your OCI instances for DDoS protection, SSL termination, and static asset caching.
2. Use Docker & Docker Compose: Containerize all services so you can easily migrate or spin up services with zero vendor lock-in.
3. Automate Backups: Configure Oracle's automated volume backup policies to snapshot your instances weekly.
