Many scientists have to do high-performance computing and store large amounts of data during their work. This requires expensive equipment, and sometimes a whole IT department that supports and configures it. An effective solution can be cloud services that quickly provide access to the necessary resources, make it easy to exchange data and store it outside of local computers, and significantly reduce the cost of equipping laboratories and research centers. Cloud technologies are already widely used in mathematics, physics, archeology, atmospheric and climate research, medicine, space research, energy and other fields. They expand the possibilities of scientific research at the expense of their own capacities, contribute to the development of science in disadvantaged countries and areas, help develop international scientific cooperation, provide a high level of cybersecurity, and optimize costs and environmental impact. Cloud services are also being introduced into small startups and large businesses with a large number of employees, customers and suppliers, as they provide constant synchronization and mobility.
