Cloud technologies are technologies of distributed data processing, in which computer resources and capacities are provided to the user as an Internet service. Simply put, it is a system where all your data is stored on a remote computer (server) and its processing is also performed there. Medicine has always worked with large amounts of data, which, until recently, were simply stored in archives and then on local servers within the organization. In fact, this was the main drawback of such systems - access to information was also possible locally, which is becoming increasingly inconvenient, especially given the increasing mobility of patients and the rapidly growing volume of information. All of this has resulted in the need, in many countries, to integrate modern technology into healthcare. Over the past few years, the adoption of cloud-based systems in healthcare has been gaining momentum. To date, organizations have mainly focused on modernizing back-office systems, moving financial, operational and HR applications to the cloud. At the same time, there is a growing need to transform core medical systems and applications to improve patient care through new digital services. And that's where things are already starting to change. Cloud services are beginning to be in demand in the medical market because they offer an infrastructure that allows hospitals, clinics, insurance companies and research organizations to improve their computing resources at low cost. But those aren't the only benefits. The cloud can help support heavyweight health IT today, such as electronic health records, patient portals, mobile apps, medical devices with IoT technology, and big data analytics underpinning modern decision support systems and therapeutic strategies. Cloud technologies are transforming the way clinical research is conducted, providing enhanced support for knowledge sharing and clinical trial management. At the same time, the need for IT resources can be reduced by using cloud services, since the bulk of the responsibility lies with the cloud service provider. From an operational perspective, cloud services offer scalability and the ability to quickly adapt to rapid business growth. Because healthcare processes extremely sensitive data, modern cloud computing meets the most stringent security requirements. In particular, they provide not only protection against unauthorized access to data, but also end-to-end encryption in the transfer of information, as well as the highest level of protection against accidents and emergencies. The medical organization's need for scarce IT security expertise is also minimized because the cloud provider also provides this, which is significantly cheaper than keeping its own experts in the field. While cloud technology promises many benefits, the transition to the cloud is not as easy as it may seem. This is due to the many complex factors that need to be considered, including regulatory compliance, information security and organizational changes. Indeed, the role of information security is growing because of the increasing number of cyberattacks on healthcare providers. This has led many healthcare organizations today to consider options for deploying their systems in private and hybrid cloud environments that meet or exceed the requirements for securing sensitive data in public cloud systems.
