Theses - "The widespread introduction of architecture based on microservices made us take a critical look at the basic tools and dogmas of enterprise Architecture. The situation was aggravated by a significant decrease in the "entry threshold" to the new tool stack, which flooded the industry with developers and designers with incomplete and sometimes eclectic ideas about the theoretical basis for building complex distributed information systems. They prefer to experiment rather than "theorize", believing that since absolute knowledge does not exist, then let the market or the consumer evaluate the ready-made solution "more honestly" than listening to the criticism of technologists and fellow workers.
