Optimizing Cloud Service Models: A Comprehensive Analysis of Security and Scalability

Cloud computing is a transformative model offering universal, on-demand network access to shared resources, significantly benefiting both commercial and educational sectors. It provides reduced costs, increased storage, and flexibility, fostering widespread adoption. However, it also introduces vulnerabilities, particularly to internal threats. The challenge of maintaining high-quality services in dynamic environments has led to the concept of federated cloud computing. Despite its advantages, selecting the optimal cloud service remains complex. This paper explores cloud computing deployment models, service models, applications, security concerns, and presents a review of various models addressing these challenges.
