What are data centers? How they work and how they are changing in size and scope

A data center is a physical facility that enterprises use to house their business-critical applications and information. As they evolve from centralized on-premises facilities to edge deployments to public cloud services, it’s important to think long-term about how to maintain their reliability and security.

What is a data center?

Data centers are often referred to as a singular thing, but in actuality they are composed of a number of technical elements. These can be broken down into three categories:

  • Compute: The memory and processing power to run the applications, generally provided by high-end servers
  • Storage: Important enterprise data is generally housed in a data center, on media ranging from tape to solid-state drives, with multiple backups
  • Networking: Interconnections between data center components and to the outside world, including routers, switches, application-delivery controllers, and more

These are the components that IT needs to store and manage the most critical resources that are vital to the continuous operations of an organization. Because of this, the reliability, efficiency, security and constant evolution of data centers are typically a top priority. Both software and hardware security measures are a must.
