A data center houses the IT infrastructure used to build, run, and deliver applications and services.
It also stores and manages the data associated with them, making it a physical foundation for operating computing resources.

What a data center is for
A data center is a physical room, building, or facility that houses IT infrastructure for building, running, and delivering applications and services. It also stores and manages the data associated with those applications and services.
This makes a data center more than a place to keep equipment. It provides the physical setting in which systems such as internal business applications, websites, and cloud-based services can be run and delivered.

Who can operate a data center
A data center can be privately owned and used by one company for its own traditional IT infrastructure. It can also be a remote facility, or a network of facilities, owned by a cloud service provider. In that model, virtualized IT infrastructure can be shared by multiple companies and customers.
The ownership model does not change the basic purpose: the facility supports the infrastructure and associated data behind applications and services. When evaluating a data center arrangement, start with the services that must run and the data that must be stored and managed. Those needs shape the required infrastructure and operating model.
