Multi-site Load Balancing Definition
Multi-site Load Balancing distributes traffic across servers located in multiple sites or locations around the world to facilitate disaster recovery and business continuity.
What Is Multi-Site Load Balancing?
Multi-site load balancing, also known as global server load balancing (GSLB), distributes traffic across servers located in multiple sites or locations around the world. The servers can be on-premises or hosted in a public or private cloud.
Multi-site load balancing is important for quick disaster recovery and business continuity after a disaster in one location renders a server inoperable. GSLB multi-site load balancing automatically diverts requests away from the failed server to servers in other locations not affected by the failure.
How Does Multi-Site Load Balancing Work?
Multi-site load balancing preserves data and business continuity when there is a sudden server failure or service disruption. Multi-site load balancing redirects traffic to the nearest server not affected by the failure. The automatic application traffic management is based on predefined policies. This load balancing solution provides seamless failover and failback without the need for manual intervention, which results in a lower mean time to recovery (MTTR).
