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.
What is a Data Centre?
A data centre or data center 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.
Tier 2 Data Centre
The benefits offered by Tier 2 facilities include:

Tier 2 data centres are for small and medium enterprise customers. It is more efficient than the level II system. Secondary providers can also handle more customers.
Companies whose network traffic matches small businesses are best suited for this level. In most cases, it is much cheaper than Tier 3.

Large enterprises use tier 3 data center specifications and have the following characteristics:
- 99.982% uptime (Tier 3 uptime)

Companies that use Tier 3 providers are usually growing companies or companies that are larger than the average small and medium-sized enterprise. Most data centre companies ranked by the Uptime Institute have a Class 3 ranking.
The tier 3 also has lower charges than the tier 4. If you have a budget constraint, you can choose tier 3 and expand to higher levels in the future.
