Maintaining multiple copies of data across different servers to ensure high availability and data durability. Networking and Communication
Estimate the scale of the system to inform your architectural choices. Calculate Daily Active Users (DAU), Queries Per Second (QPS) for reads and writes, storage requirements over 5 years, and network bandwidth. If your calculations show a write QPS of 50,000, you immediately know a single relational database instance will not suffice. Step 3: High-Level Design (10-15 mins)
