Bonding (or link aggregation) combines multiple physical network connections into a single logical connection.
For Redundancy
If one physical connection in the bond fails, traffic continues flowing through the remaining ones without an outage.
For Increased Throughput
Some bonding configurations combine the bandwidth of multiple connections, effectively multiplying available capacity for a single server.
Where It's Used
Enterprise servers and data center infrastructure commonly use bonding for both the reliability and performance benefits, rarely relevant for typical shared hosting customers directly.
