7 System Architecture Patterns Every Developer Must Know | System Design | Satyam Scripts

Coding is the easy part. Building systems that scale, survive traffic spikes, and don't collapse when one service goes down — that's what separates a senior developer from everyone else. And it all starts with knowing the right architectural patterns.

In this video we break down the 7 patterns that show up in every high-scale system design interview and every production codebase that actually works.
What we cover:

Microservices — breaking monoliths into maintainable, deployable units
Event-Driven Architecture — real-time systems that react instead of poll
Sidecar Pattern — keeping your main code clean while offloading logging and security
Strangler Pattern — migrating legacy systems to modern code without downtime
Horizontal Scaling — handling unlimited traffic without a single point of failure
Serverless — writing functions and letting the cloud handle everything else
API Gateway — the single entry point that manages security and traffic across all microservices

Whether you're prepping for a system design interview or just trying to level up how you think about backend architecture — these 7 patterns are the foundation.

💬 Comment "doc" and I'll DM you a detailed breakdown of all 7 patterns.
