3 Challenge: Conflict Between the Unified Access and Server Performance Server cluster 1. A cluster does not provide a unified interface. Users can access services only of a single server separately. 2. The system does not support any redundancy. If faults occur on a server, users that have accessed to the server are affected. 3. Services of a server cluster are not scheduled and managed in a unified manner. Service access requests are excessively frequent on some servers. These servers cannot respond to the requests in time. However, some servers receive a small volume of service requests. Resources of these servers are wasted.

4 LB Benefits Load balancing and unified access: Unified scheduling improves resource utilization efficiency. The cluster provides a unified access point for users. Failures of a server do not affect user experience. Server cluster
