Abstract

The article is devoted to modern engineering approaches to building scalable and fault-tolerant high-load systems. It defines key architectural principles that ensure predictable system behavior under increasing load, distributed data processing, and complex multi-component integrations. Methods of reliability engineering, observability, and architectural models used by the world’s leading technology companies are examined. Special attention is paid to the role of horizontal scaling, distributed architecture, and SRE culture in ensuring the resilience of digital products. The article is intended for engineers, architects, and technical leaders seeking to apply structured methodologies when developing mission-critical systems.

Keywords: High-Load Systems, Scalability, Fault Tolerance, Reliability Engineering, Distributed Architecture, DevOps, SRE, Observability.
