What is Data Centre - Which tier (1,2,3,4) is right for your business

Every day, we check emails, post our latest updates to various social media platforms. Some of us even manage our personal blog or website. Have you ever wondered what is behind all these online activities? When you post or upload something online, where does the data go?

The answer is Data Centre.

But, what is a data centre?

A data centre is a facility composed of networked computers and storage. Companies, big or small, use the facility to organize, process, store and distribute large amounts of data. Enterprises usually rely heavily on the applications, services, and data contained in the data centre, making it the focus and key asset of their daily operations.

Data Centre Tier Ratings. How to choose the right tier for your business?

When looking for a data centre, it’s important to understand these ratings because they can provide you with uptime guidance, and uptime determines how long the data centre can be fully operational.

Uptime Institute‘s rating began in the mid-1990s. This is a white paper, “Classification Defines Site Infrastructure Performance”. The purpose is to outline the standards for data centre design and investment. Since then, these ratings have been helping data centres achieve high-quality levels to ensure uptime.

Data centres can be divided into 4 tiers. Each tier has increasing requirements.

Tier 1 Data Centre

Small businesses usually take advantage of the requirements of Tier 1 data centres, which have the following characteristics:

  • 99.671% Uptime
  • Zero redundancy
  • 28.8 hours of annual downtime
  • If you are a small business, tier 1 may be ideal for you. This is a cost-effective solution.
  • Although tier 4 data centres do not have the functions of large centres, they have generators or backup cooling systems.
