How a server handles thousands of simultaneous connections depends heavily on its underlying design pattern. Non-Blocking I/O vs. Thread-Based Architectures
: Communication patterns, network protocols, and how the OS interacts with your backend application. What You Will Learn
In the modern digital landscape, we often judge a book by its cover—or an app by its interface. We marvel at smooth animations, intuitive drag-and-drop features, and responsive buttons. However, beneath every polished user interface lies a hidden world of servers, databases, APIs, and logic. This hidden world is . udemy fundamentals of backend engineering
Created by Meta, GraphQL solves the common REST problems of over-fetching (getting more data than you need) and under-fetching (not getting enough data, requiring multiple API calls). With GraphQL, clients submit a precise query detailing exactly what data they want, and the server returns exactly that—nothing more, nothing less—via a single endpoint. gRPC and Webhooks
A transaction groups multiple operations into a single unit of work. ACID properties guarantee that either all operations succeed or none do, preventing data corruption when multiple users try to modify the same data simultaneously. How a server handles thousands of simultaneous connections
