It has been known as a paradigm in which a shared pool of computing resources is accessible for users. The rapid growth of the healthcare environment provides better medical services to reduce costs and increase competition among healthcare providers. Despite its crucial role in the cloud, no thorough study exists in this domain. This article presents a systematic study for healthcare services in the cloud environment. A well-organized overview of all the databases has been explored. By clustering the research goals of the found papers, we have derived four main research groups. We have further evaluated the papers concerning the background of the paper, QoS parameters, application area, or methods used for applying and formulating the main ideas presented in the works. This survey emphasizes the challenges, needs, benefits of using cloud computing in healthcare systems and provides a comprehensive and detailed study on cloud healthcare services, strengths, and weaknesses of the existing methods. Highlighting cloud health services can be the major focus of research for developing the urban healthcare system.eninfo:eu-repo/semantics/closedAccessAuthentication SchemeDisease PredictionRisk-AssessmentIotEnvironmentsOptimizationArchitectureEfficientSecurityQueryAuthentication SchemeDisease PredictionRisk-AssessmentIotEnvironmentsOptimizationArchitectureEfficientSecurityQueryReview733WOS:00076854870000110.1002/ett.44732-s2.0-85126184705N/AQ1
