I've probably written a lot about how people link their shops, companies, businesses, and products online to advertise it globally and to basically sell more stuff. It's one way of getting your business known to others, thus, in that way you are also expanding it. Right? But once you're linked online, it takes a whole lot to maintain it. So we have companies who offer things like data center virtualization to save you the hassle of losing data in you quest to make your mark online. No matter how much of a techie you are, you still need help from people who make it their mission in life to make yours easier. =)
