The first is pure technical means, that is, when a user connects, the node that determines based on the current load of the system to process

Load balancer can be used with LVS scheme, but to prevent single point of failure, you can choose lvs+keepalived combination to ensure high availability Focus : Each node synchronizes timeNtpdate time.windows.com1.
