In the end it is supposed to be a decentralised AWS/cloud computing service with the benefits that computation is more or less private (limited to no snooping) and (the actually important bit) with market driven pricing that seems to be driving the cost below that of AWS. Sia and a number of other projects are trying to address hot and cold storage while Golem and company are addressing the compute. With some clever architecture design, these decentralised systems could be combined to make a decentralised remote server.
