That information includes the monthly price, the hourly price and tecnical characteristics of the virtual load balancer. Among the tecnical information you will see the amount of memory, the number of processors, the bandwith limit and the máximun number of farms.
Once you select the desired new size of your load balancer click on the bottom bar labeled "RESIZE". The process will take some time to finish with the reassignment of the new resources.
