I have a vps, what i need? 1gb ram? x gb? transfer size?
I'm not an expert on this... I followed the complete how-to on a clean debian box (8 XEON cores, 16Gb RAM). When i look at my server, it's load is around 0.2, and about 2,5 Gb memory was used... So i guess you can run an electrum server on a VPS, given that you have some swap space. Altough, during the loading fase where you install bitcoind and load the blockchain, a sufficient amount of processing power and ram might speed things up
