Is data center a cloud? The main difference between the public cloud and a data center is where the data is stored. In a data center, data is most often stored on the premises of your organization. Some data centers may be in locations not owned by your organization—in this case, your data center is colocated, but not in the cloud.
How is data stored in data center? Data centers contain physical or virtual servers that are connected internally and externally through networking and communication equipment to store, transfer and access digital information. Each server has a processor, storage space and memory, similar to a personal computer but with more power.
Why do we need data center? Why are data centers important? Data centers support almost all computation, data storage, and network and business applications for the enterprise. To the extent that the business of a modern enterprise is run on computers, the data center is the business.
