Layer 7 Load Balancing

Layer 7 load balancing refers to managing network traffic at the application level of the OSI model, which is responsible for delivering user data and ensuring proper application communication. This type of load balancer directs requests based on content, such as URL or headers, allowing for more intelligent routing. For example, it can send image requests to a server optimized for media, while sending API requests to another server. By efficiently distributing traffic, Layer 7 load balancing enhances performance and reliability of web applications, ensuring users have a smoother experience.
