How is a High Availability deployment referred to compared to a Load Sharing deployment?

In a High Availability (HA) deployment, the configuration focuses on ensuring system uptime and redundancy. This setup typically involves one unit being active and the other unit standing by, ready to take over in case the active unit fails. This is referred to as an "active/standby" configuration because only one unit processes traffic at a time, with the standby unit waiting to engage when necessary.

In contrast, a Load Sharing deployment allows multiple units to share the load of processing traffic simultaneously, which is termed "active/active." In this setup, both units are active and working together, distributing the network traffic between them.

Therefore, the distinction between High Availability and Load Sharing can clearly be understood through these terms: "active/standby" for High Availability as it emphasizes redundancy and failover, and "active/active" for Load Sharing as it emphasizes efficiency and traffic balancing.
