What are datacenters?

The Internet is a big place. With so much data traversing the globe everyday, how do companies WHAT ARE DATA CENTERS? ensure that their data is stored and processed securely? The answer lies in data centers, which are vital to the function of nearly every business. Let's take a look at how data centers work and the key THE BRAINS OF THE OPERATION role they play in managing our data. GLOBAL SCALE Total global data center traffic THE Storing data on the cloud doesn't mean that it's not stored on hardware. A cloud provider is maintaining CLOUD 2018 (еxpected) the data on their own host servers at a data center. 2013 Expected cloud* traffic to 8 10 account for data center traffic. 76% zettabytes* Cloud Traffic *What's a zettabyte? That's one sextillion (1021) bytes! Where are these 8,600,000,000,000,000,000,000 bytes in the future going to be stored and processed? DATA CENTERS. Think of a data center as the heart of a network. They provide a central location to house servers that collect, store, and process data, THE DATA HUB which companies access remotely via the Internet or over private networks. Data centers provide all the required elements to support servers: storage, backup and recovery, power, cooling, security and physical protection. THE DATA CENTER LAYOUT HEAT EXCHANGERS SERVER ROOMS CONCRETE AND STEEL CONSTRUCTION Located on the roof, they release the hot air from inside the building. House clusters of interconnected servers in a secure, climate-controlled room. Servers are essentially a computer without a monitor or keyboard. They store and process data Built to protect servers in the event of natural disasters. and connect to a network for input/output. AIR CONDITIONING Controlling the temperature is vital to prevent equipment from overheating. BACKUP GENERATORS Run on diesel and automatically turn on in the event of a power outage.
