System Design and Architecture

Scale a service under rising traffic and see every trade-off in motion.

What you’ll learn

  • Load balancers, caches, queues and databases as pieces you wire together
  • Watch p99 latency climb as traffic grows, then fix it
  • Replication, sharding and failure, simulated tick by tick

For example: Add a cache until p99 drops below 100 ms.
