Where,

Weight
Controls the number of requests that are directed to the application server. Even though you specify a value of 0 to 20 as the weight of a server, the weight that is assigned to the server is a proportion, in which, the weight assigned to the server is the numerator, and the sum of the weights of all members of the cluster is the denominator.
