Introduction to Self-Healing Systems I've spent years building and maintaining complex systems in production, and one concept that always seemed appealing was self-healing. The idea that my system could automatically detect and fix issues without human intervention was a dream come true. Honestly, who wouldn't want that? But as I delved deeper into implementing self-healing mechanisms, I discovered a phenomenon I call the "Dual Loop Law" – where self-healing can actually hurt your system. I was working on our 3-server setup last Tuesday when I realized just how big of a problem this was. The Dual Loop Law I had implemented a self-healing loop that would detect failed services and restart them automatically. This seemed like a great idea, as it would reduce downtime and minimize the need for human intervention. But turns out, this loop was causing more problems than it was solving.…
