Enterprise information systems are always prone to high loads during active sessions. This issue is becoming more and more actual with the increase of digital enterprise systems. The key to the solution is the use of load-balancing algorithms, which ensure system stability at high workloads. This work analyzes common load balancing algorithms and provides a comparison analysis. The paper also performs a complexity analysis of load balancing algorithms, differentiating between the static and dynamic algorithms. The results show that static algorithms are easy to implement, yet they are unable to adapt to different changes. Dynamic load balancing algorithms require deeper knowledge of the system, but at the same time providing higher efficiency in changing environments. This research paper also provides a recommendation for selecting a load-balancer for enterprise information system.
