ABSTRACT
In the previous chapter, we covered the defi nition of Cloud services and the different types of Cloud services. We also reviewed examples of previous manifestations of similar ideas.
Various surveys including those by IDC [1], Gartner [2], Mimecast [3] and others indicate a large and rapidly growing market for Cloud services across various industries. These adoption numbers seem to indicate two things: fi rstly, that Cloud-based services have certain advantages over the traditional packaged software and secondly, that some percentage of prospective users continue to have reservations about using Cloud services.
