System Design: Break, Fix, and Scale Your App

Summary

Outcast HQ shares a new system design course video that deliberately breaks an app under heavy traffic, then tackles each bottleneck with load balancers, replicas, caching, and queues. The practical approach shows why architectural tradeoffs matter as AI makes writing code easier.

๐Ÿšจ New video just went live!

Building an app with AI is easy. Surviving popularity is the hard part.

In this system design course, we take a perfectly good app and break it ๐Ÿ’ฅ. On purpose. Over and over.

Every time it crashes under the traffic, we fix exactly one thing ๐Ÿ› ๏ธ (load balancers, replicas, caching, queues) and learn the hidden cost of adding it.

System design isn't about perfectly clean architecture. It's about deciding how your app is allowed to be wrong, on purpose.

AI can write the code, but making that call is your job ๐Ÿซต.

Let's break some things.
