At least from my point of view, it could be difficult to distinguish between a Cloud and a Data Center. As this article says, people often think about these in terms of data warehousing but it is difficult to know specifically the main differences.
One of the most important differences is capacity. Although both systems have a huge capacity, the cloud one is unlimited and, in several cases, public and this is one of the reasons that allows it to be more accessible. Then, the data center is created to firms that do not need a constant increase on its data amount.
