This video is Part 2 of the WhatsApp system design series, where we move from architectural thinking to concrete diagrams, real-world workflows, and documented decisions.
We build on the foundation from Part 1 and focus on how WhatsApp-like systems work at global scale.

🎯 Key Takeaway:

Part 1 covers requirements, event storming, component breakdown, quanta, and architecture style selection.
