The existence of a robust model is just one component of the solution, and not the whole of Generative AI (GenAI) systems, to be successfully implemented. We consider in this chapter a systematic strategy to build high-strength and useful GenAI systems, various kinds of failure (hallucinations and biases amplification), and recommend architectural design patterns of high availability and high scalability, such as global load balancing and multi-region models. This is to be displayed by required operating principles, e.g., retrieval-augmented generation (RAG) to make the information accurate, and circuit breakers in sufficient performance of the system. Improving the reliability, best practices, etc. Observability on the basis of metrics, logs, and traces is significant to continuous monitoring of pro-active and model governance. These technical, working factors may help facilitate the application of a GenAI through proof of concept to an effective production level. Our conceptual framework proposes a method via which we can design trusted systems in the future yet not relying on the cloud.
