System design is choosing the boxes and arrows behind an app, and knowing how they behave when millions of people show up. This track starts with requirements and honest back-of-the-envelope numbers, grows one server into many behind a load balancer, and adds caches and CDNs. Then it tackles the hard parts: scaling the database, queues and duplicate messages, rate limits, consistency, and seeing inside a running system.
Most lessons are concepts, small numbers and diagrams, with code only where it makes an idea concrete. The track ends with you designing a home feed and a live leaderboard, step by step.

מה תדעו לעשות
- Turn requirements into load estimates with back-of-the-envelope math
- Scale stateless servers behind a load balancer with health checks
- Use caches, TTLs and CDNs without serving stale or unreachable content
- Scale a database with pooling, replicas and, as a last resort, sharding
- Move slow work to queues and make consumers safe against duplicates
- Choose consistency per feature and alert only on what users feel
