Layer 4 Load Balancing

Layer 4 load balancing refers to distributing network traffic based on basic data like IP addresses and port numbers. Think of it as a traffic cop directing data packets to different servers based on where they're coming from and what they’re asking for. This method is fast and efficient, handling large amounts of data, but it doesn’t analyze the actual content of the data. It helps ensure no single server becomes overwhelmed, maintaining smooth and reliable access to online services.
