Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Comparative Analysis of Technologies for Constructing Distributed Information Automated Systems for Complex Objects Integrated Modelling V.A. ZELENTSOV, V.A. SOBOLEVSKII Using the example of the sustainability integrated assessment problem for forest ecosystems, a comparative analysis of software and technology solutions for building information automated systems for integrated modeling (IAS) of complex objects is performed. The main requirements for complex modeling systems are formulated: scalability, ease of operation and high manageability, availability and fault tolerance, deployment speed and adaptability to load changes, cost-effectiveness, the ability to include different types of calculation models, as well as organize the processing of heterogeneous source data, including Earth remote sensing data and video streams from ground and airborne surveillance equipment. Based on the analysis of these requirements, a basic technology for building an IAS is defi ned, based on the use of container orchestration systems with multiservice architecture components. The proposed technology provides a solution to the problem of integrating heterogeneous distributed software components operating in various software environments, allows for maximum automation of data processing, and reduces dependence on the human factor, thereby minimizing errors in assessing the actual state of forest vegetation and other complex objects. Keywords: integrated modeling, information automated systems, technologies, integral assessment, container orchestration system, sustainability, forest ecosystems.
