Load balancing and failover serialization

Load balancing and failover 1, mission objectives

This task is to solve the server load balancing and failover, this load balancing is to achieve a true sense of load balancing, the actual use, according to the server's various performance indicators for task allocation, in order to achieve fast response, experience high effect. Second, failover is a complement to load balancing that combines fast response and high availability. The goal of this task is not only to achieve, but also to avoid hardware changes and additions, software-level implementation, reduce implementation costs.

The task environment is Windows Server R2, IIS7.0 or more.

2. Solutions

Because the environment is in Windows, considering compatibility issues, special consideration is given to using the Network Load Balancing components and the failover cluster components that are available with the Windows Server R2 system.
