There are levels to this question. If you are Junior, you just need to explain the flow. But if you are Senior, you need to design the architecture from scratch. In this video, I’m trying something completely new. The architecture is so in-depth that it’s practically impossible to use the whiteboard. So, we are moving to the laptop to break down exactly how YouTube handles billions of users, from the upload flow to the streaming experience. ⭐ Here is what we cover (with timestamps): 1️⃣ Junior vs. Senior Expectations — How the "Design YouTube" interview question changes based on your experience level. (0:00) 2️⃣ The "Farmer & Distributor" Analogy — A simple mental model to understand content distribution before getting technical. (2:10) 3️⃣ The Creator Flow — How massive files are chunked, uploaded via Edge Locations, and authenticated through API Gateways. (4:45) 4️⃣ Behind the Scenes Processing — Using Kafka queues, Metadata extraction, and the custom "Argo" chip for transcoding. (6:40) 5️⃣ Database Architecture — Why we use Cassandra for metadata, ElasticSearch for queries, and BigTable for comments. (9:15) 6️⃣ The Viewer Experience — Adaptive Bitrate Streaming (ABS), CDNs, and how the recommendation engine delivers content.
