Sovereign AI Lakehouse - Zero-SPOF Cloud & Local RAG Lakehouse on Free-Tier OCI

👋 Hey Product Hunt community! I'm Aamir (@Amz34), an infrastructure engineer and data architect. Like many developers, I was frustrated by the exorbitant cloud bills required just to run real-time streaming and local AI RAG pipelines for testing and production edge cases. So I engineered Sovereign AI Lakehouse — an open-source reference architecture that deploys a 100% Zero-SPOF enterprise streaming + AI lakehouse on OCI's Always-Free ARM tier ($0/month). ### 🛠️ What's Under The Hood: 1. Zero-SPOF Multi-AD IaC: Automated OpenTofu landing zone across fault domains in OCI Jeddah (me-jeddah-1). 2. 512MB Redpanda Streaming: Kafka-compatible event ingestion handling 10,000+ IoT/industrial events/sec capped at 512MB RAM. 3. Columnar Lakehouse: DuckDB + Polars + PostgreSQL for ultra-fast vector & analytical queries. 4. Air-Gapped Sovereign RAG: Local bge-m3 embedding model + ChromaDB running without any external API calls or data egress. ### 🌟 100% Free & Open Source Everything is published under the MIT license on GitHub: 👉 https://github.com/Amz34/enterpr... I would love to get your feedback, hear what workloads you'd like to benchmark, and answer any questions about OCI Always-Free configs! If you find this useful, a star on GitHub would mean the world! ⭐
