I need a server with very big size of RAM, so around a ~1TB, for a GIS DB, that would be not written to hard disk, because the data is irrelevant after a seconds. So i do not need a lot of disk space, i wish to hold all data in memory. So i need powerful CPU and very big RAM space. The write data would be 1% of INSERT'S and 99% of UPDATE's. Write/Read ratio would be 20/1. I have a choose, rent a dedicated server or rent a Amazon service. The problem is, that I don't understand, how to calculate the price of Amazon services. Traffic ~100TB/month.
Does not exists any calculator script for this purpose?
