Foundations and Emerging Paradigms in Distributed Computing

Distributed computing is a computing model in which multiple interconnected computers work together to perform tasks as a single system, improving scalability, performance, and reliability. Its foundations include concepts such as transparency, communication through message passing or remote calls, synchronization, consistency management, and fault tolerance using replication and redundancy. Traditional architectures like client–server, peer-to-peer, clusters, and grids established the basis for sharing resources across networks. Emerging paradigms such as cloud computing, microservices, edge computing, serverless platforms, and blockchain have expanded distributed systems to support large-scale, real-time, and data-intensive applications. These advancements enable flexible, resilient, and efficient infrastructures that power modern technologies including big data analytics, IoT, and artificial intelligence services.
