Layer 4 load balancers route traffic based on IP address and port configurations without inspecting application payloads, while Layer 7 load balancers inspect application message contents like headers, cookies, and JSON payloads.
Layer 4 load balancers handle only UDP traffic, whereas Layer 7 load balancers handle only TCP traffic.
