Cloud services in healthcare use internet-based remote servers to store, manage, and process medical data and applications, enabling secure, scalable, and cost-effective solutions for Electronic Health Records (EHRs), telemedicine, data analytics, and operational management, shifting from expensive on-premise systems to flexible models like IaaS, PaaS, and SaaS for improved efficiency, accessibility, and patient care. Key benefits include reduced costs, enhanced data sharing, real-time access, and support for AI/ML, but they also introduce security and compliance challenges.
