Server Load balancer and Redundancy

Server Load balancer and redundancy are two different technologies that can be used independently, but they can play a powerful role only when combined. Generally, they are both used in combination.

Server Load balancer (SLB): distributes traffic to servers. It is also called round robin. It is similar to distributing playing cards. All servers that distribute traffic to websites are activated.

Redundancy Technology: it is also called a server cluster, but only one server is activated. Other servers are used as backup servers. The backup server is activated only when the server is down.

Assume that a website has three shunt servers A, B, and C (ABC is activated), A1, B1, and C1 (a1b1c1 is in sleep state) they are backup machines A, B, and C, which are load redundancy technologies.
