One of the most prominent trends in cloud computing is making business services available through the Internet. Cloud storage is an example of this trend in action, being the practice of storing data on virtual storage space maintained by cloud storage service providers. Businesses, particularly small and medium-sized businesses, find services such as cloud storage useful because they are cheaper than their in-house counterparts. Not only are businesses spared from purchasing and then setting up the in-house solutions to such problems, but the maintenance needed to keep such solutions running are handed over to the service providers. Furthermore, cloud computing services are scalable, meaning that businesses pay for what they use and nothing more.
