Cloud infrastructure technologies form the backbone of modern computing by providing scalable, flexible, and cost-effective resources for deploying and managing applications. With the rapid growth of digital transformation, organizations increasingly rely on cloud infrastructure to sup-port dynamic workloads, big data processing, and distributed systems. This paper presents a comprehensive review of cloud infrastructure technologies, including virtualization, containeriza-tion, software-defined networking, and distributed storage systems. It examines key service mod-els such as Infrastructure as a Service, Platform as a Service, and Software as a Service, high-lighting their roles in enabling efficient resource management and service delivery. The study also explores the importance of automation tools, orchestration frameworks, and infrastructure as code in optimizing cloud operations. Security, performance, scalability, and reliability aspects are ana-lyzed in the context of modern cloud environments. Additionally, emerging technologies such as edge computing and serverless architectures are discussed for their role in enhancing cloud capa-bilities. The review concludes that cloud infrastructure technologies are continuously evolving to meet the growing demands of modern applications and digital ecosystems.
