Emerging Paradigms in Cloud Computing: Towards Sustainable, Secure, and Intelligent Architectures

Abstract Cloud computing has evolved into the backbone of modern digital transformation by enabling flexible, scalable, and cost-efficient services to enterprises, governments, and individuals. Despite its immense growth, cloud platforms face challenges related to energy efficiency, security, interoperability, and inclusivity. Traditional centralized architectures consume large amounts of energy, leading to sustainability concerns, while rising cyberattacks necessitate robust security models. Moreover, with emerging paradigms such as blockchain, serverless architectures, and edge computing, there is a growing need to reimagine cloud design for improved trust, efficiency, and accessibility. This paper presents a comprehensive framework for sustainable and intelligent cloud computing, integrating green resource management, blockchain-based security, and edge–serverless synergy. Extensive literature review, proposed architecture, and real-world case studies highlight how the next generation of cloud platforms can reduce carbon footprints, ensure trustworthiness, and extend cloud access to underserved regions. Finally, experimental analysis demonstrates potential improvements in latency, cost savings, and sustainability, establishing this framework as a pathway for inclusive and secure cloud transformation.
