The experience of developed countries of the world and developing countries in carrying out digital transformation of social and economic processes that can be carried out on the basis of digital platforms, which allows to increase their efficiency and form information systems for the provision of high-quality digital services, is studied. The necessity of transformation of digital processes at the level of the state, regions, business and family is substantiated. The importance of innovative mechanisms for the integration of new institutions or new categories is highlighted business entities in the IT sector, whose role as service integrators is growing significantly, as it allows for the effective interaction of network services with any business entities, government agencies and households. It is determined that in order to ensure a high level of digitalization using digital platforms, it is advisable to develop a set of measures to ensure the reliability of information data (Big Data) and close interaction between all participants in the IT services market; high level of cybersecurity; standardization and unification of such processes. We propose to consider platformization as a process of dynamic changes in the organization of activities of all market participants based on the use of modular digital platforms, service (cloud) technologies, as well as the related transformation of the concept of business models in the direction of their maintenance. We believe that the educational sector should offer a methodical approach to the implementation of innovative systems for improving the competencies of specialists in the field of digitalization of the economy, social sphere and interpersonal relations based on the all-consuming use of IT technologies. The existence of digital gaps in the coverage of online education in developed and developing countries has been proven. The concept of digital transformation of socio-economic systems in the context of the Fourth Industrial Revolution has been developed.
