This paper presents an example of the formation of a digital educational ecosystem, developed at the Teacher Training Institute of North-Eastern Federal University (NEFU), as an integral socially significant multi-level system, whose participants are students and employees of the educational system of the republic. In general, the digital educational ecosystem is a socio-technical ecosystem, which includes a set of interacting independent educational and social actors, representing students, educational institutions, and a variety of potential customers of educational services. The important thing for the functioning of the digital educational ecosystem is the availability of resources: material and technical, human resources represented by teachers with formed digital competencies, software (digital educational resource), and used modern technologies (blended learning, distance learning technologies, and so on). It is expected that practical activities within the project should create collective digital competencies, will accumulate new intellectual capital, and will develop new mechanisms of collaboration in the interaction of new participants from the perspective of territorial, geographical, national, and other aspects.
