I live out in the middle of nowhere (Brazil interior). I have been reading a lot about cloud computing. I use an Ubuntu server in my wifes office (file server, print server, DHCP, and backup). We have 5 computers on our LAN. I am upgrading to 9.10 and am wondering if we need cloud computing. I am not sure what it is or if it would be something that would benefit our office. Could someone shed some light on what cloud computing is and how we could use it in our small LAN.
