Running Production AI Agents on Oracle Cloud Free Tier

The article discusses how the Oracle Cloud free tier can be used to run production-grade AI agents, contrary to the common perception that it's just a student sandbox. The author shares their experience of running a multi-agent orchestration system, bot endpoints, vector storage, and more on the free tier infrastructure.

Details

The author has been running a production-grade AI agent infrastructure on the Oracle Cloud free tier for months, serving real customers and maintaining high uptime. The free tier provides 4 ARM cores, 24GB RAM, and 200GB storage, which is more generous than the free tiers of AWS or GCP. The real value, however, lies in the production-grade features that Oracle doesn't gate behind paywalls. The author runs a multi-agent orchestration system, WhatsApp and Telegram bot endpoints, vector storage for RAG pipelines, real-time monitoring, and backup failover instances - all on the free tier. The key constraint is the limit of two VMs, which forces architectural decisions around managing physical servers rather than spinning up new instances for every microservice. The ARM-based VM shapes are capable for AI workloads, but memory management is crucial, with each agent process taking 200-400MB baseline and vector operations spiking to 2GB. The author also highlights the benefits of the free Autonomous Database, which provides fast, reliable, and autonomous state management for conversation histories, user preferences, agent performance metrics, and workflow definitions.
