Green Cloud Computing Data center is the key

The biggest challenge for cloud computing is that the

  IT industry is a big contributor to energy consumption and data centers are large emitters.

According to a global authority, Gartner, the IT industry accounts for about 35 million tonnes of carbon dioxide a year, accounting for 2 of the total global emissions and a large carbon emitter in the data center. Global Data Center carbon emissions will reach 205.9 billion tonnes in 2020, becoming the fastest growing factor in ICT carbon footprint. Another Greenpeace report observed that by 2020, Golden Globe's main it operators "cloud computing" (including data processing and telecommunications network 1 of energy consumption, nearly 2,000,000,001,000 watts, more than Germany, France, Canada and Brazil, the total energy consumption of four countries.

A Low-carbon economy will accelerate the realignment of market order. The green energy utilization rate, directly affects the enterprise core competition strength, the well will become the enterprise not more the lifeline. At the same time, the Low-carbon economy has brought new opportunities to the IT industry. Despite the global recession, the 2008-year income of the low-carbon sector has risen by 75%. The Low-carbon economy, with green energy as its core, is the most ideal sustainable economic model of global consensus, which contains huge business opportunities. HSBC's research provides strong evidence that companies in the Low-carbon sector (including renewable power generation, nuclear power, energy management, water treatment and waste disposal) accounted for more than $534 billion trillion in 2008, exceeding the total business of the aerospace and defense industries of 530 billion.

in China, the IT industry's energy consumption is also staggering, in the cloud computing practice, if the green energy development and utilization, the domestic IT industry will be in the future of international competition in trouble.

The United States is one step ahead of the Low-carbon economy, and IT companies are sparing no effort to build a green data center, from government to business, and there are many ways that we can learn from it.

One is the government's suspension. In 2001, the Environmental Protection Department launched a "Green energy partner" project aimed at attracting renewables users to build energy generation projects for wind, solar, biomass, geothermal and other renewables. Over the past three years, more than 1200 business members have purchased 7 billion dry-watt hours of green energy, saving carbon dioxide equivalent to 644,000 families L years of electricity consumption.

Two is energy loss. Companies are signing "renewable energy transfer" contracts with public utilities to buy renewable-energy credits, such as Texas, a farmer using wind power, transferring renewable energy credits to Starbucks, and selling his power to the local grid, and Starbucks just through local utilities, To buy electricity for their shops.

Three is enterprise self-help. Pepsi-Cola, which has been buying renewable-energy credits, recently announced that it will not trade in electricityAfter three years of spending 300 million of dollars in the wood and developing renewable energy at its site, Intel's extensive energy-saving projects have saved 660 million of energy for the division and will be assembling a series of solar projects in the coming months. Microsoft is setting up a new European "large Data Center" in Berlin to reduce reliance on mechanical cooling by taking advantage of the cold local climate.

The development of green energy, the sustainable way, this is the future of China's economic development of the basic universal. It industry in the cloud when the green energy as the support, thus stepping into a benign sustainable development path.

Building a cloud computing solution

Green Data Center is the trend, virtualization, cloud computing can improve the efficiency of data center, so that the

reduce energy consumer, this is the industry's consensus. The concept of cloud computing advocates and pioneers ', most of them focus on the data center for the entire cloud computing opportunities. Whether it is virtualization, cloud computing technology and service providers, or switches, routers, application delivery equipment and other network infrastructure products enterprises, are in the cloud computing services to build a data platform, improve user Service input greatly enthusiastic, from different directions to help the user's data center to the green shift.

Cloud Computing is Google's first, and currently Google and industry Mazon companies in the application of the leading, but IBM is a combination of hardware and software "Elephant", Microsoft has the world's largest software users, Their respective cloud computing schemes essentially migrate and extend existing hardware and software technologies to cloud computing, and other companies are unmatched. There are people in the industry that analysis.

Microsoft is not the pioneer of cloud computing, but it can be said to be behind. Microsoft's 2008-1l-month release of Windows Azure platform officially opened its own cloud-computing scene. Today it has the fate of the company's future in the cloud computing, in recent years, Microsoft will spend 90% of the company's resources (manpower) in the cloud-related business. In Microsoft's view, cloud computing is a technological evolution. It can be divided into several major phases:

1, traditional datacenter. It is built often in accordance with the maximum demand to do, than the end of the month or quarter more busy, you will certainly according to its highest requirements to do hardware and software configuration, resulting in the traditional data center utilization ratio is low, according to the relevant data, think is generally 15% or less than 15%.

2, virtualization Data Center. Traditional data center construction does not take into account the energy-saving million-face things. How can you improve its utilization? Is virtualization, the first is to improve the utilization of the data center, Microsoft believes that this indicator can be raised to more than 50%: The second is to reduce costs. Of course, the premise is to manage well, if the management is not good, will bring more trouble.

Extends to cloud computing, Microsoft wants cloud computing, information Services, computing resources, just like water and electricity, so handy that users don't have to build a power plant to do this, and at the moment Microsoft has two main types of cloud for users to choose from, namely the public cloud and the private cloud. Microsoft has launched a public cloud platform named Windowsazureplatform. The cloud is run by Microsoft itself, providing users with a variety of application hosting services. The Windowsazure platform currently offers platform-service (PaaS)-type services, but Microsoft has announced the upcoming launch of Vmrole. In addition, Microsoft offers live services for individual consumers and online services for businesses.

At the same time, Microsoft offers private services that provide products and services to customers who want to build a private cloud. This private cloud is deployed within the customer's own data center to deploy the applications and services they need based on personalized customer requirements. Of course, when using cloud computing, users can use the above two different deployment types of cloud computing services.

Another cloud-computing leader, IBM, has been leading the virtualization landscape since the 60 's, and has recently launched the New Enterprise data Center vision. Also launched a new generation of cloud data center concept, let us see the next generation of data center development trend. The core of IBM's vision for

is the resilience of data centers however, the data center to achieve flexibility is not easy, if the data center is a simple drawing into the hardware and software 2 levels, the future of IBM's data center will be the bottom of the hardware, including servers, storage and network equipment fully virtualized, At the top of the software is the integration of the SOA architecture, so that the data center can achieve the desired operating environment, that is, to create a shared environment, data can be based on the different needs of business type, the temporary collocation of a variety of applications. Reach a service-oriented it architecture.

The IBM New Enterprise Data Center solution is based on virtualization and green technology, combining the web-centric cloud computing model with the advantages of the current enterprise data center, for all types of industry enterprises in the IT resource control, IT management unified, operation and maintenance cost control, resource sharing to improve utilization, Power consumption control, rapid response to demand and other aspects of convenience and operational efficiency.

According to IBM's vision, businesses will take a simplified, shared, dynamic, or resilient, three-stage deployment to achieve a transition to a new enterprise data center.

IBM believes that this new enterprise-class data center will be the key to enterprise deployments in the next few 10 years.

    However, the entire new Enterprise data center construction solution can not rely on the IBM company to complete, in addition to IBM's launch of the mainframe SYSTEMZ10, IBM and Jie, NETAPP, VMware, APC, A number of companies such as Intel cooperate. As a construction team to establish a new enterprise-class data center, we can meet the needs of enterprises.

Cloud Computing is based on high-performance computing, so a powerful and intelligent computing engine is critical in the cloud infrastructure. Hpbladesystensmatrix is what HP built for cloud computing--the body-building infrastructure. Based on HP Blade system and its virtual connection technology, storage system and management software, the system builds a virtual resource pool covering computing, storage and network infrastructure, and an admin domain can be extended to up to 1000 physical and virtual servers.

HP's solution is a combination of capacity planning, coordination management, disaster recovery, and other integrated services to automate infrastructure provisioning and reduce operational costs and power savings. By accessing the appropriate application infrastructure templates directory through self-service portals, the matrix can be used to coordinate the resources of each resource pool in the embedded environment to support appropriate enterprise applications. The

Novell has recently completed a turnaround in enterprise positioning through multiple acquisitions. Experts from Novell said. In the past few years Novell has been able to provide the infrastructure of a complete data center from the bottom to the top, starting with the traditional operating system manufacturers, making system management software and doing business software. Novell has a unique advantage in the assessment, migration, and scenario design required for the data center virtualization process. For example, Novell's assessment tool can be completed locally in the User data center to complete the evaluation process, and the current market cap more than the assessment of the user to upload the data to the vendor evaluation system to complete the evaluation, so that the user data sensitive to the needs of the telecommunications operators similar to the demand.

Novell has been in the domestic customer has no practice, is Tencent. For example, Tencent to online a network game, in the introduction of the virtualization scheme, the data center to avoid the previous purchase of the server approval process, in one hours may be online, but the cost of accounting more complex than the original, there is the problem of billing. Moreover, data centers are all about dynamic management, the workload will flow, for a while on the physical machine, for a while on the virtual machine, Novell management tools can be unified control of the data center, integrated management, dynamic discovery of resources, in the private cloud Master virtual machine platform, physical machine platform utilization, and the deployment of resources, At the same time for operators to provide a variety of billing interface, audit interface.

In addition to the above cloud computing aspects of the comprehensive platform and software enterprises. Data Center Network Equipment SupplyCompanies have launched data center Network Solutions for computing, to meet the data center network integration and Green, Low-carbon direction.
