Azure Cellular Architecture: Scaling with Cosmos DB Change Feed and Service Bus

1. Introduction Scaling cloud-native systems often results in a massive, highly interconnected web of services where a single corrupted payload or regional brownout can trigger a global outage. Cellular Architecture mitigates this by decomposing the system into completely independent, isolated failure domains known as "cells." In this tutorial, you will build a highly resilient event-driven architecture using Microsoft Azure, combining the cellular pattern with an asynchronous workflow (Azure Co
