Once the requirements are locked in, sketch out the bird's-eye view of the architecture.

Define the contract between the client and the server. Outline the exact REST endpoints, GraphQL schemas, or RPC parameters needed to satisfy the functional requirements. 4. Data Model and Schema Definition

: Step-by-step guides for designing essential components such as API Gateways , Load Balancers , Distributed Caches , Asynchronous Queues , and Unique ID Generators .

To design any large-scale application, you must master the fundamental building blocks of distributed systems. Interviewers look for your ability to piece these components together logically. Horizontal vs. Vertical Scaling

The best way to access the material is through legitimate platforms like Amazon or directly from the author's official distribution channels.
