Concept Explanation gRPC (gRPC Remote Procedure Call) and Protocol Buffers (Protobuf) are powerful technologies designed for high-performance, low-latency communication in distributed systems. gRPC and Protobuf are widely adopted in microservices architectures by companies like Google, Netflix, and Uber, enabling efficient,…

Introduction Representational State Transfer (REST) APIs have become a cornerstone of modern software architecture, facilitating seamless communication between clients and servers in distributed systems. As of 05:39 PM IST on Friday, October 10, 2025, REST remains a dominant paradigm for…

Concept Explanation REST (Representational State Transfer) and GraphQL are two prominent paradigms for designing APIs, enabling communication between clients (e.g., web or mobile applications) and servers in distributed systems. Both are widely adopted in modern architectures, powering applications at companies…

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…

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…

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…

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…
