Load Balancing

The main purpose of load balancing is to optimize resource utilization, maximize throughput, minimize response time, and avoid overloading any single resource.

OSI L4 vs OSI L7 load balancing

L4 load balancing is focused on network-level traffic distribution, while L7 load balancing is focused on application-level traffic distribution and can perform advanced functions such as SSL offloading, content-based routing, and application-layer security. L7 load balancers are typically more feature-rich and complex than L4 load balancers, but may also be slower and more resource-intensive.
