There are perhaps six reasons to switch. First, Google offers a simple cloud-based infrastructure. By switching, customers are able to make use of a variety of applications, which under traditional circumstances would cost a huge amount of money individually.
Second, and following on from the last point, businesses can also save a lot of money by not having to purchase license fees. I haven’t counted the number of apps available but there are a lot, and Google seems to be incorporating many more over time.
The software is also integrated, with access being just a click of a button away. This includes Gmail, GDocs and so on.
Furthermore, as Google Apps for Business is a cloud-based system, access is easy. All that’s required is an internet connection. This means that you can use any mobile device and work anywhere in the world. Any business that isn’t at least looking at using mobile technology combined with cloud I think are missing a trick.
A fifth and related point is the fact that cloud is designed for collaboration. Since collaboration within a business and between businesses is massively important, then here again a business that isn’t using cloud is missing out.
Finally, and perhaps more pertinent for Google rather than cloud in general, users get a very generous 25GB allocation for use on their Google Mail account. Not to mention how well ordered Gmail is.
