Layer-4 is the transport layer in the OSI model, and layer-7 is the Application layer. OSI MODEL LAYER-4 LOAD BALANCER A layer-4 load balancer has an established connection with the back-end and sends the data to the dedicated back-end for the particular request and gets the response back. Azure Load Balancer operates at layer 4 of the Open Systems Interconnection (OSI) model. Itu0027s the single point of contact for clients. Load balancer distributes inbound flows that arrive at the load balanceru0027s front end to backend pool instances. These flows are according to configured load-balancing rules and health probes.

These load balancers operate at Layer 4, the Network layer, and load balance the load balancers. Layer 4 load balancing. At Layer 4 the load balancer acts just like a firewall. It routes connections between servers and clients based on simple IP address and port information, combined with health checks. This Transport Layer manages end-to-end connections. Layer 4 handles flow and error control, data communication between devices, systems ... A load balancer acts as the 'traffic cop' sitting in front of your servers and routing client requests across all servers capable of fulfilling those requests in a manner that maximizes speed and capacity utilization and ensures that no one server is overworked, which could degrade performance. Layer 4 load balancing uses information defined at the networking transport layer (Layer 4) as the basis for deciding how to distribute client requests across a group of servers. For Internet traffic specifically, a Layer 4 load balancer bases the load-balancing decision on the source and destination IP addresses and ports recorded in the ... Layer 4 Load Balancing - Avi Networks Layer 4 load balancing, operating at the transport level, manages traffic based on network information such as application ports and protocols without visibility into the actual content of messages.
