Key Principles & Goals
Explore the fundamental principles like scalability, reliability, maintainability, and efficiency that guide system design decisions.
What Guides Design Decisions?
Why are some apps fast and rock-solid while others crawl and crash? Good system design. Let us explore the core principles that guide every decision.
Principle 1: Scalability
First, scalability: when your app goes viral, it must grow without crashing. Think adding lanes to a highway as traffic climbs, not widening the old ones.
