Аннотация:This paper is devoted to the digital transformations
and digital economy programs. In particular, we are considering
programs for the transition to a digital economy in the Russian
Federation. It is obvious that telecommunications represent the
basis for digital transformations. The paper discusses the
software development and mathematical modeling issues relating
to the program of Digital Economy, in particular, "Digital
Economy of the Russian Federation”. The main focus of our
review is an information infrastructure. As examples of digital
transformation, we are considering the largest information
systems in the US. It seems to us that the lessons of their
implementation are applicable to Russian problems. We discuss
the movement from circuit switching to packet switching and
some challenges of transformation. We consider information
network interfaces (control points) and discuss Federal
Enterprise Architecture, namely, e-Government. Particular
attention is paid to issues of cybersecurity and to the issues of
system modeling, which, in our opinion, are greatly
underestimated.
