Load Balancing Algorithms
TCP load balancers employ various load balancing algorithms to determine how traffic is distributed among the backend servers. The choice of algorithm depends on factors like server health, available resources, and the desired distribution strategy. Common algorithms include round-robin, least connections, and IP hash.
What is a TCP load balancer?
A TCP load balancer, also known as a Layer 4 load balancer, operates at the transport layer of the OSI model and is designed to distribute network traffic based on information available in the TCP/IP protocol. This type of load balancer is commonly used to enhance the performance, scalability, and reliability of applications by efficiently distributing incoming TCP traffic across multiple servers or resources.
