Verma, Ashutosh (2025) A comparative analysis of cloud providers for scalable and reliable systems. World Journal of Advanced Engineering Technology and Sciences, 15 (2). pp. 2520-2529. ISSN 2582-8266

This article presents a comparative assessment of major cloud providers (AWS, Microsoft Azure, and Google Cloud Platform) for building scalable and reliable systems in today's digital landscape. It evaluates the architecture, features, and economic considerations that influence cloud adoption decisions across enterprises. The comparison encompasses three critical dimensions: scalability capabilities including auto-scaling mechanisms and containerization support; reliability features such as high availability architectures and fault isolation boundaries; and pricing models with cost optimization strategies. Through detailed examination of each provider's technological approaches and business models, the article illuminates their distinct strengths and suitability for various organizational needs. AWS demonstrates comprehensive breadth and depth of services, Azure excels in enterprise integration and hybrid capabilities, while GCP offers performance advantages in networking and innovative pricing structures. The insights provided offer decision-makers concrete criteria for selecting cloud infrastructure aligned with their specific operational requirements, existing investments, and strategic objectives.
