In today's digital age, cloud computing has become a staple in many industries, including the medical field. These services contribute to improving operational efficiency, enhancing the quality of healthcare, and enabling rapid access to medical data. Cloud computing stores electronic health records and accesses them from anywhere and at any time. Doctors and patients can obtain health information quickly, which contributes to improving the speed of diagnosis and treatment . On the other hand : cloud computing reduces IT infrastructure costs. Instead of investing in expensive on-premises server hardware, medical organizations can use cloud resources on a subscription basis, reducing operational costs . Cloud computing provides high levels of security to protect sensitive health data. These services include data encryption, two-factor verification, and backup and restore features, which protects data from loss or hacking . Cloud computing also allows medical institutions to quickly expand the scope of their services to keep pace with increasing demand, such as increasing the number of patients or expanding medical services. Cloud resources can be increased or decreased as needed without complications . Cloud computing has several applications, including:<br />Electronic Health Records (EHR): The cloud is an ideal place to store and manage electronic health records. Doctors can easily access a patient's medical history, previous diagnoses, and treatments, which contributes to providing better health care .<br />Telemedicine: Cloud computing enables remote medical consultations, which helps bring healthcare to remote areas or groups that have difficulty accessing health facilities. Doctors and patients can communicate via video, and access medical records necessary to make treatment decisions .<br />Health data analysis: The cloud is used to analyze big health data, which helps discover health patterns and trends. These analyzes can be used to improve disease management, predict epidemics, and develop effective health strategies .<br />In conclusion, there are some challenges in cloud computing, as protecting health data remains a major challenge. Medical organizations must ensure compliance with laws and regulations related to data protection, such as the General Data Protection Regulation (GDPR) and the Health Insurance Portability and Accountability Act (HIPAA). Another challenge is service reliability , as medical institutions rely heavily on the availability of cloud services. Cloud service providers must ensure service continuity and provide the necessary technical support to avoid service interruption .
