Design of Disaster Recovery and Load Balancing Strategies in Traditional Centralized Distributed Web Systems

Abstract

This paper proposes an effective disaster recovery strategy and load balancing strategy for web systems based on traditional centralized distributed architecture, which are widely used in small and medium-sized enterprises. In the disaster recovery strategy, we have designed a global backup strategy and single node backup strategy to adapt to different system requirements and fault recovery scenarios. In the load balancing strategy, we take the database as the starting point, calculate the load proportion of task execution nodes, effectively determine the load status of each task execution node, and make the load of each task execution node in the distributed system tend to be balanced. The research results of this paper have certain reference value for improving early developed web systems with the same architecture. Future research will focus on optimizing the efficiency of disaster recovery strategies, improving the accuracy of load judgment, and exploring innovative methods to enhance the scalability and stability of web systems based on centralized distributed architecture.
