NLB (Network Load Balancing) is a technology used to distribute the workload of a server across multiple servers. This helps to improve performance, scalability, and availability of the system.
Benefits of using NLB:
1. Improved Performance: NLB distributes the workload of a single server across multiple servers, thus improving the performance of the system. For example, if you are running an e-commerce website, NLB can help balance the load of the website across multiple servers, thus providing a better user experience.
2. Improved Availability: NLB helps provide high availability by ensuring that if one server goes down, the workload is automatically shifted to another server. This helps to ensure that the system is always available and running. For example, if you are running a web application, NLB can help ensure that the application is always available even if one of the servers goes down.
3. Improved Scalability: NLB helps to easily scale the system by adding more servers to the cluster. This helps to improve the scalability of the system and allows it to handle more traffic. For example, if you are running a web application and the traffic increases, you can easily add more servers to the cluster to handle the increased load.
