The governance case for keyless Azure: why shared keys are a liability, how managed identity plus RBAC fixes it, and how security, network, and platform teams enforce it.

I keep a page like this open in a browser tab. When a team asks which pattern fits a new service, I would rather point at a decision tree and a comparison table than argue it from memory for the third time that month. So I wrote the reference I wanted: the 16 patterns I actually reach for in .NET systems, each with its diagram, a code sketch, and the trade-off it forces on you.

TL;DR: This guide walks you through building a production-ready RAG system using FastAPI, ChromaDB, MinIO, and OpenAI. Learn document chunking, vector embeddings, hybrid search, and real-world deployment strategies. Introduction # As a .NET developer watching the AI space move fast, I found myself both excited and skeptical. When tools like Claude.ai and ChatGPT started offering out-of-the-box RAG solutions, I wanted to build my own system with full control over the implementation.

The Birth of the Stretch Tracker: A Developer’s Story # As developers, we often find ourselves deeply immersed in our work, sitting for hours on end in front of our screens without even realizing how much time has passed. I was no different. During a particularly intensive project, I noticed the toll these long coding sessions were taking on my physical health - back pain, stiff neck, and decreased productivity became unwelcome companions in my daily routine.
