Raya DC Cloud Migration.
Rather than run your own hardware or pay for use of some specific hardware in someone else's data center, you just pay for access to a massive pool of computing resources provided by Microsoft. This allows you to host web servers, email servers, databases, file storage servers, virtual machines, user directories, or anything else you might want. When you need more computing resources, you don't have to purchase physical hardware. Azure shares the hardware and automatically assigns the work, as necessary. You pay for as many computing resources as you need, and not a specific number of hardware servers on a rack somewhere. Services you deploy in this way can either be public servers available to everyone, or part of a "private cloud" that's just used in an organization.
