lbd (Load balancing detector) is a Linux tool that helps you find the load balancing of a website. This tool detects load balancing using DNS and HTTP. And it’s very easy to operate.
Load balancing definition?
Load balance is the process by which network traffic is distributed across multiple servers. This ensures that no server is overloaded. By spreading the work evenly, the load balance improves the response of the application. It also increases the availability of applications and websites for users.
