Replication is one of the most important concepts in distributed systems, powering everything from databases to large-scale cloud infrastructure.
In this video, we break down how replication actually works, the math and probability behind system reliability, master-slave and peer-to-peer architectures, synchronous vs asynchronous replication, and the real tradeoffs engineers make while designing scalable systems.
If you want to understand distributed systems beyond surface-level definitions, this video is for you.
