Enjoy Green cloud computing

Cloud computing can help companies reduce their energy costs by 12.3 billion of billions of dollars a year, which means a 85.7 million metric ton of carbon dioxide emissions per year for 10 consecutive years, according to a report by Verdantix research.

Last year the Pike Survey Company pointed out that using cloud computing could reduce energy consumption in global data centers by as much as 38% by 2020, compared with the growth rate of energy consumption in traditional data centers that have not shifted to the cloud. According to a survey last year by Microsoft, Accenture Consultancy and WSP Environment and energy consultancy, the transfer of business applications to the cloud could reduce carbon emissions by 30% for large, energy-efficient companies, and 90% for small and inefficient companies.

The reasons for energy saving in cloud computing are as follows:

1. Economies of scale. For large cloud computing providers, the overall increase in energy efficiency is cheaper because costs can be spread across a large number of servers and dedicated services are available to improve energy efficiency.

2. Diversity and aggregation effects. Cloud Computing Data Center has a large user community, these users distributed in different regions, have different habits of use. The diversity of user groups makes the data center as a whole in use, thereby increasing resource utilization. Traditionally, the utilization of internal data centers is generally at 5%-15% or lower, while the infrastructure utilization of major cloud service providers is as high as 30% to 40%.

3. Flexibility. Cloud facilities use virtualization and other advanced technologies to rescue software from physical servers (some people call it "physical abstraction in the virtual layer"). IT services are transferred from a traditional "rely on a hardware device" to a "dependent network". For example, if the software is routed through the perimeter of a physical server that is down, you don't need to run all the servers; And you can optimize the server design, discard the power of large equipment to reduce energy consumption.

4. Avoid organizational problems. Most companies have problems communicating with the IT department responsible for the purchase of the server and the Logistics department responsible for paying the electricity bill. Cloud service providers solve this problem to a large extent, they usually have a very clear data center budget and assign permissions to a certain person, so there is no communication problem.

At present, many manufacturers have made a lot of efforts in the green environment of cloud computing.

World Cloud Box launched the first domestic electric power operation of the commercial cloud Computing data center-cloud box is a very typical example.

Compared with the traditional data center PUE value 2.2~2.8, the energy Efficiency (PUE) of the cloud box can be reduced to the 1.18~1.63, and the calculation density is higher, and the power of the single cabinet is 5 times times that of the traditional cabinet, which can save 75% of the space. Through the use of efficient refrigeration technology in the closed space, the cloud box can greatly shorten the path of the cold and hot airflow, ensure the maximum utilization of the refrigeration capacity, so that the energy efficiency is greatly improved, the PUE value can be reduced to less than 1.3. Compared with traditional data center, the power consumption of cloud box can be reduced by 50% and the operating cost is reduced greatly. As early as 2009, Dell, together with Granville, in its latest launch of a cloud computing server vs11-vx8 first adopted the power of the Low-power processor nano. Industry insiders believe that this means that green computing for cloud computing has achieved a key stage results.

Using green computing to reconstruct cloud computing, allowing green computing to penetrate every level of cloud computing, is an inevitable trend for future cloud computing.
