Cloud Data Center 101: What is and How to differentiate them?
What is Data Center Tier?
Founded in 1993, Uptime Institute has been committed to the exploration and research of data center infrastructure for more than 20 years, and is a globally recognized data center standards organization and third-party certification body.
Sustainability is an important standard basis for enterprise cloud computing infrastructure availability, reliability, and operations management service capability certification.
The standard was developed by uptime's long-term experience in the field of data centers combined with the accumulation of end-user knowledge and has had a profound impact in the industry. Based on the above two standards, Uptime TIER level certification is the most well-known and authoritative certification in the data center industry, and cloud data center has been highly recognized worldwide.
With the development of data center business on a global scale, higher and higher requirements are put forward for the reliability of data centers, and the acquisition of high reliability level certification will bring more business opportunities to data center owners. At present, there are more than 1,000 data centers in 85 countries around the world that have passed the citic telecom certification issued by Uptime.
How Important is Data Center Tier?
One level to another in a data center means additional expenses – for setting up capital expenditures, information security solution and maintaining its operating expenses, and the cost gap between levels is even more significant. Obviously, service providers pass on the cost of data centers to consumers. Therefore, the choice of data center should not be based only on availability factors, but also on the needs of IT to make deployments.
In most cases, Tier-II data centers are already able to meet most of the sd wan availability requirements. Therefore, the average small and medium-sized enterprise will not consider and need to use the third to fourth level data center.
Differences between 4 Data Center Tiers
Choosing a data center asia pacific should not only consider availability factors, but also consider the cost of hosting the system without causing waste.
Tier I, for traditional small businesses
- Power availability 99.671%.
- Downtime < 28.8h/year
- Redundant component N
- Parallel maintenance is not available
- Cost index 70%.
- There are no redundant devices
- Emergencies require frequent shutdowns
- Susceptible to harsh weather
- Any unplanned interruptions or failures are affected
- The infrastructure needs to be completely shut down to carry out annual inspections and repairs of the building
Tier II, Small and Medium Enterprise
- Power availability 99.9%.
- Downtime <8.76h/year
- Redundant component N+1
- Parallel maintenance cloud data center is limited
- Cost index 100%.
- Redundant structure reduces service interruptions
- Independent generator and moisture barrier
- More than 6 hours of power storage equipment
- There is a separation from the other data areas
- Redundant components are used to perform annual inspections and repair work of the building
- Single-path mains power connection
Tier iii+ data center, a large enterprise with operations all over the world
- Power availability 99.982%.
- Downtime < 1.58h/year
- Redundant component N+1
- Parallel maintenance is limited
- Cost index 136%.
- The infrastructure is the same as level 2
- Dual-path mains access (one with one backup).
- IT equipment must be equipped with dual power sources
Tier IV, a giant international enterprise
- Power availability 99.995%.
- Downtime <0.44h/year
- Redundant component 2N+1
- Parallel maintenance has sd wan
- Cost index 215%.
- The infrastructure is the same as level 3
- Independent dual-path mains access (simultaneous operation).
- 2N+1 redundant components
Types of Data Centers
According to the cpc different service objects, the data center is divided into enterprise data center and Internet data centers.
Enterprise data center is built by the enterprise or organization itself, providing data processing, data access and other information services for internal employees, associated customers, and partners, which can be a single-level advanced threat protection or a multi-level data center, or it can rent an IDC computer room to outsource IT operation and maintenance to a professional company.
Internet data centers are owned by service providers and provide paid information services to customers via the Internet. Due to the wider range of service objects, such data centers are generally larger in scale and the equipment and platform are relatively high-end. Its typical applications, such as MSN or QQ and other services similar to network hard disks, or the capacity space provided in telecommunications to small and medium-sized enterprises, small and medium-sized enterprises through data center backup software to backup local data centralized in the data center and so on.
