Benefits of SLB

SLB improves network performance by:

Server Load Balancing

The server load balancer changes one of the source and destination IP
addresses. When a packet arrives from a client to a server, the load
balancer changes the destination IP from the Virtual IP address to the
Real IP address. When a packet is sent from a server to a client, the load
balancer changes the source IP address from the Real IP address to the
Virtual IP address.

• Minimizing server response time.
• Maximizing server availability.
• Increasing server utilization and network bandwidth. This is
accomplished by balancing session traffic between the available
servers, according to rules established during configuration.
• Increasing reliability. If any server fails, the remaining servers
continue to provide services seamlessly.
• Increasing scalability. Server configuration can be performed
without disrupting the network.
