Stop Building Fragile Systems! A Guide to High Availability

Scaling your system to millions of users is a massive achievement—but what happens when a single server fails? If your platform goes dark, your scale doesn't matter. In this video, we move beyond just "handling load" and dive deep into Architecting for Resilience. We explore why Availability is the ultimate measure of trust in engineering. From the mathematical beauty of "The Nines" to the high-stakes world of multi-region redundancy and circuit breakers, we break down how to build systems that stay online even when the world is falling apart. What you’ll learn in this video: The Scaling Gap: Why availability is different from scaling and reliability. The Power of Parallelism: How to turn "unreliable" parts into a 99.9999% stable system. Failure Modes: Understanding the 4 culprits: Hardware, Software, Network, and Human Error. Redundancy Strategies: Active-Passive vs. Active-Active and the "Backhoe Scenario." High Availability Patterns: Load Balancing, Database Replication, Queue-Based Leveling, and the legendary Circuit Breaker. If you’re a software engineer, system architect, or a student preparing for system design interviews, this deep dive is for you.
