Resumen
The article develops the design features of data-intensive systems. Sources of recent years are analyzed, international experience in creating information systems is considered, the concept of high load is formulated and common practices and technologies are listed. Based on a number of sources on this topic, it has been revealed that specific solutions for developing the application infrastructure are selected individually, depending on the features of the project and the tasks to be solved. At the same time, the basic requirements are universal for the sphere of information systems: the reliability, the scalability or ease of maintenance and the architectural patterns used in the design. The article summarizes new information, including international experience in this area, and draws conclusions about the most common practices in the design of high-load systems.
