AWS Cellular Architecture: Scaling Event-Driven Systems with DynamoDB, SNS, and SQS

1. Introduction In the cloud-native era, scaling an architecture often leads to a massive, interconnected system where a single failure can cause a global outage. Cellular Architecture solves this by decomposing the system into independent, isolated failure domains called "cells." In this tutorial, you will build a highly resilient event-driven architecture by combining the cellular pattern with an asynchronous flow (DynamoDB Streams, AWS Lambda, Amazon SNS, and Amazon SQS). Instead of a single
