COVID-19 has pivoted the way we do business today. Data centers have helped transformed digital commerce and online businesses giving digital infrastructure a vital role in business operation and growth. What are data centers? A data center is a centralized facility that houses storage systems, routers, servers, security devices, and electrical switches where data can be accessed virtually thru applications and websites. As money is deposited in a bank, data is stored in a data center. Data centers are not only repositories but also the ones that process, back up, and recover a large amount of data.

What's the best type of data center for your use? The most common data centers are colocation, cloud, and hyperscale. Colocation data centers provide physical space, power, and cooling systems for servers and connections to local communication networks. Some of the most reliable colocation data center companies are QTS Realty Trust Inc (NYSE: QTS), Digital Realty (NYSE: DLR), and Equinix (NASDAQ: EQIX). Cloud data center, on the other hand, is a host of different companies in one facility such as IBM Cloud (NYSE: IBM).

On the contrary, a hyperscale data center is a facility that is run by the company that it supports. The e-commerce giant Amazon has Amazon Web Services. Other most popular data center giants are Microsoft and Google to name a few. Green data centers are gaining popularity as well for promoting sustainability for maximizing energy efficiency while minimizing the environmental effects of a traditional data center. Some of the green data centers you may know are Facebook (NASDAQ: FB) wherein they were able to reduce the number of backup generators because of locally generated hydroelectricity on their site in Lulea, Sweden. Apple (NASDAQ: AAPL) on the other hand utilizes solar, wind, hydro, and geothermal resources to support their cloud services and operations. According to a recent study of Technavio, the hyperscale market alone expects a compound annual growth rate of 21% from 2020 to 2024 even with the impact of COVID-19. The construction of green data centers in North America accounts for the positive growth rate during the forecasted period.
