What are data center tiers?
Data center tiers are a method devised by the Uptime Institute to evaluate data center infrastructure. The Tier Classification System provides the data center industry with a consistent method to compare typically unique, customized facilities based on expected site infrastructure performance, or uptime.
There are four data center tiers:
Which tier should you choose for your business?
Tier I and Tier II data centers are typically sufficient for businesses that can tolerate occasional server downtime after regular business hours or on weekends. For those businesses that do not need 24/7 uptime, colocating or hosting in a Tier III or Tier IV data center may involve extra investment that is not critical.
However, for multinational companies whose business is run 24/7 around the globe or for companies where any downtime will adversely affect their business (e.g., airlines, SaaS, gaming companies, just to name a few), choosing a Tier III or a Tier IV data center is optimum.
Are you interested in managed hosting or co-location in a data center? The majority of Zenlayer data centers are Tier III or Tier IV. For more information regarding hosting, contact a representative.
