Can a unified approach to the creation of services to cover all the possible use cases and scenarios for new services? The paper emphasizes the need to address the prevailing trends in the design to create a standard. Also, we highlight the critical importance of such a thing as the time to market for new applications and services developed according to the proposed standards.
