Multi-Cloud and Hybrid Cloud Strategies: A Comparative Study of Adoption Models

Abstract

As enterprises increasingly migrate to cloud environments, the choice between multi-cloud and hybrid cloud strategies has become a defining factor in shaping digital transformation. While both approaches aim to optimize performance, cost efficiency, and resilience, they differ in architectural models, adoption drivers, and operational complexities. Multi-cloud strategies emphasize the use of multiple cloud service providers to mitigate vendor lock-in and enhance flexibility, whereas hybrid cloud combines public and private cloud infrastructures to balance scalability with security and compliance. This paper provides a comparative study of adoption models for multi-cloud and hybrid cloud, analyzing technological, organizational, and economic perspectives. It further examines real-world case studies, challenges such as interoperability and governance, and future trends such as AI-driven orchestration. The study concludes that while both strategies offer transformative potential, the choice of adoption depends on organizational priorities, regulatory landscapes, and evolving digital ecosystems.
