A data center is an in-house data storage setup by internal experts. It comprises of physical and virtual elements for better management and storage. Cloud computing, on the other hand, is not a physical setup, the service is only available in the cloud.  It is a data storage service that is virtually available, making internet mandatory for access.There are many similarities between the two, making the decision of suitability a tricky one. As per the general analysis, small businesses with limited capital and other resources should opt for on-demand and subscription-based cloud data centers. And companies that have enough capital and resources, whereby they feel the need to exercise complete control and employ great security should then opt for in-house data centers.
