Concept Explanation A webhook is an event-driven mechanism that enables asynchronous communication between systems by allowing one application to send real-time data to another application via HTTP callbacks when specific events occur. Webhooks have become a fundamental component in modern distributed systems,…
Concept Explanation Real-time communication is a cornerstone of modern web and mobile applications, enabling instantaneous data exchange between clients and servers for functionalities such as live chats, stock tickers, real-time notifications, and collaborative tools. Technologies like WebSockets, Long Polling, and Server-Sent Events (SSE) are…
Concept Explanation Service discovery is a critical mechanism in microservices architectures, enabling individual services to dynamically locate and communicate with one another in a distributed, scalable environment. Microservices have become a dominant architectural pattern for building large-scale applications, such as…
Concept Explanation An API Gateway is a specialized server that acts as a centralized entry point for managing, routing, and processing API requests in distributed systems, particularly in microservices architectures. API gateways have become indispensable for modern applications, enabling seamless interaction between…
Concept Explanation Load balancers, reverse proxies, and API gateways are critical components in modern system design, each serving distinct yet overlapping roles in managing network traffic, enhancing performance, and ensuring security and scalability. These technologies are fundamental to distributed architectures,…
Concept Explanation A proxy server and a reverse proxy are intermediary systems that facilitate communication between clients and servers, but they differ fundamentally in their orientation, purpose, and operational context. These technologies play pivotal roles in modern network architectures, addressing…
Concept Explanation A Content Delivery Network (CDN) is a geographically distributed network of servers designed to enhance the delivery speed, reliability, and scalability of digital content, including web pages, images, videos, and applications, to end-users across the globe. CDNs have…
Concept Explanation The Domain Name System (DNS) is a hierarchical, distributed naming system that serves as a critical infrastructure component of the internet, facilitating the translation of human-readable domain names (e.g., www.example.com) into machine-readable Internet Protocol (IP) addresses (e.g., 192.0.2.1).…
Concept Explanation System design interviews are a critical component of technical evaluations for software engineering roles, particularly at leading technology firms, where candidates are assessed on their ability to architect scalable, reliable, and efficient systems. The “10 BIG Questions of…
Concept Explanation Answering a system design interview problem demands a systematic and structured methodology to effectively demonstrate an understanding of architectural principles, trade-offs, scalability considerations, and practical implementation strategies. System design interviews are designed to assess a candidate’s capability to…
