Distributed Computing Architectures: Scaling Modern Software in Multi-Cloud Environments

Cheekuri, Karthik Chakravarthy (2025) Distributed Computing Architectures: Scaling Modern Software in Multi-Cloud Environments. World Journal of Advanced Engineering Technology and Sciences, 15 (3). pp. 508-515. ISSN 2582-8266

This article details the fundamental principles and implementation strategies of distributed systems that enable modern software applications to support millions of concurrent users across multi-cloud environments. The transition from traditional centralized architectures to distributed paradigms reveals how resource sharing, concurrency management, and fault-tolerant design contribute to enhanced system resilience. We introduce the Resilience-Latency-Consistency (RLC) taxonomy as a novel framework for evaluating architectural decisions in distributed systems. Key scaling techniques include horizontal expansion, data sharding, and load balancing, alongside comparative assessments of prevailing architectural models such as client-server, peer-to-peer, and microservices. Case studies of production systems from leading technology organizations illustrate practical applications of these principles. Emerging trends in edge computing, serverless architectures, and the influence of hardware innovations on distributed system design provide insights into future developments. Effective orchestration of distributed components proves instrumental in delivering responsive, globally accessible applications that maintain performance integrity even under extreme usage conditions.
