In the past, when running a large web application, it was necessary to run a large web server. Because your application attracts a large number of users, you will have to add more memory and processors to your server. Today, the "Large server" model has passed, replacing it with a large number of small servers, using a variety of load balancing technologies.The advantages of "more small servers" over the "l

replaced by the backup switch. The vrrp virtual gateway address is configured on the terminal in the network. When a fault occurs, the virtual switch remains unchanged and the host remains connected. The network will not be affected by single point of failure, in this way, the core switch switching problem in the network is well solved. 4 vrrp for Server
