Preface





IT industry continuous development and innovation, on the one hand bring more wonderful perfect user experience, on the other hand also in the process of increasing energy consumption on environmental resources caused pressure. Green Environmental protection is our hot topic, cloud computing is the trend of it, when Green computing encounter cloud computing, green cloud can become feasible?





It energy consumption





in the 21st century, when people's environmental consciousness reaches an unprecedented level, new energy, emission reduction and green economy are more and more appearing in front of us. In the focus on heavy industry, mineral mining, processing, transportation and other traditional industries energy consumption, we ignore it this new industry has sprung up.





current IT-related emissions have become one of the biggest sources of greenhouse gas emissions, with 860 million tonnes of carbon emissions in 2007, and a rapid growth in emissions in this sector. Data center energy consumption accounted for 56% of the total cost, including 36% of the power and 20% of the mechanical (refrigeration) costs. And even as people improve energy efficiency in devices and data centers such as equipment and components, global IT-related carbon emissions will reach 1.54 billion tonnes by 2020.





Marvell Technology CEO Zhou Xiwen pointed out that the world every year there are more than 300 million computers, 1.2 billion mobile phones, and more than 100 million TV sets put into use, 10 years after the cumulative is likely to be more than 20 billion sets of electrical appliances. This means that the world will have to build about 200 nuclear power plants to meet this demand.





in the traditional concept, electronic games, software programs and other virtual applications of resources consumption is very low, but the fact is not as people wish:





Virtual Community Game "Second Life" individual energy consumption per virtual role is greater than the average energy consumption of a Brazilian, and a 15000-person virtual community consumes a unit of electricity that has reached the energy consumption of a small town in Brazil.





Local web Game "Happy Farm", since 09 has become one of the hotspots, New Year's Day before and after the breakthrough 1 million. According to statistics, happy farm the highest number of active users more than 16 million people, the resulting electricity consumption is amazing.





And as the world's largest search engine, Google consumes 100 million-kilowatt of the electricity per year, if the 5 cents per degree to calculate the words, Google's annual payment of electricity costs amounted to 50 million yuan.





as one critic put it, virtual life has no form, but it leaves traces.





Green Computing





"Green computing" refers to people to reduce the use of information technology hardware energy consumption, such as the consideration of power consumption, space occupancy, heat dissipation and other factors to achieve energy saving, environmental protection requirements. One of the traditional ways is to turn off the power or limit the power consumption of the server when the facility is not in use. For example, companies like healthcare are using energy Star, which is said to have saved millions of of dollars.





in order to solve the problem in the product design, it can be reformed from the following aspects:





chip: Power consumption is a major goal in the design of a chip, many times more important than how fast it can run. The traditional CPU in the same chip produced a large number of transistor structure, and let it run in a very high frequency, the result is CPU chip consumption of electricity and generated more and more heat, increase the energy consumption of the server, and the system design to bring heat is not easy problem. Today, chips made up of 1 billion transistors will leak 60~70 watts of electricity. How to reduce the power consumption per unit of chip under the same performance, this research mainly revolves around the research and development support multi-core, multithreading chip. Companies such as Intel, Sun, ARM and Samsung are investing a lot of human resources in this area, touting their chipset performance per watt rather than simply emphasizing simple performance.





IDC Transformation: The use of IT resources in the enterprise is inefficient, only a very small number of computing resources (about 3%) is really effective use, a large server group brings strong demand for electricity. Existing solutions include: memory power off technology, reduce the power consumption of free memory chips, water-cooled technology, speed up heat dissipation. such as the IBM Power Server provides such a green feature. Digiplex,scandinavian, a data center company, claims that putting servers in their Oslo machine rooms is greener than anywhere else in Europe because 99% of Norway's electricity comes from hydroelectric power.





Software: Increase system usage (7% ~50%) through cloud computing and virtualization technology, thereby reducing the number of servers. Of course, this requires a higher degree of data security and network security.





In addition, the use of more efficient power supply system, using dynamic cooling technology to speed up the heat dissipation, the promotion of green PCs and peripherals, photovoltaic energy, pay attention to equipment recycling, etc., are the application of green computing ideas and positive effects.





Cloud Computing




The core idea of
cloud computing is to provide a large number of network-connected computing resources/systems/software as a always-on service, which can be run on hardware devices that provide public services and reduce actual it resource input.




The three service models for
Cloud computing include SaaS, PaaS, IaaS.





Saas:software as a service software. It is a way to provide software leasing over the Internet, eliminating the cost of software acquisition by users.





Paas:platform as a service platform. It is an application of the SaaS model and submits the software development platform as a service to the user. The advent of PAAs can accelerate the development of SaaS, especially the development of SaaS applications.





Iaas:infrastructure as a service infrastructure that serves. Consumers can get services from a sophisticated computer infrastructure through the Internet.





in the past two years, cloud-related application services through Microsoft, Google, Amazon, Salesforce, and other major IT giants in the global scope gradually promoted.





Microsoft's cloud-based operating system Windows Azure was officially commercially available in 2010, with the main goal of providing a platform for developers to help develop applications that run on cloud servers, data centers, the Web, and PCs. Cloud developers can use Microsoft's Global data center's storage, computing power and network infrastructure services. The Azure Service platform includes the following major components:





l Windows Azure;





l Microsoft SQL database service, Microsoft. NET service;





L Live services for sharing, storing, and synchronizing files;





l for business Microsoft Share Point and Microsoft Dynamics CRM services.





and Salesforce.com as the world's first formal provider of commercial applications of cloud computing has been a great success in the past 10 years, the annual revenue has been more than 1.4 billion dollars, more than 72,500 paid customers, cloud computing as a mature technology platform for the world's many businesses have provided a good solution 。  Salesforce.com is not only responsible for physical and environmental security, but also provides infrastructure, application and data-related security-control solutions that greatly reduce the user's responsibility and human and material requirements in running and using.





Blue Shield "green cloud"





in fact, the idea of green computing has been reflected in cloud computing. Blue Shield shares on the definition of green cloud more focused on its practicality, integrity and product shape, that is, the concept of green computing, cloud computing service model for the framework, security applications for the bottom and research and development to meet the energy-saving, efficient, security of the three major needs of the network security products.





1 High Performance low Power architecture





To achieve lower power consumption of equipment performance, the Blue Shield shares from the chip architecture to optimize. We have focused on the latest MIPS64 architecture, which delivers up to 48GHz of 64-bit computing power in a single chip, which delivers high performance and application acceleration for secure data centers and cloud computing applications. In addition, the processor uses a new technology that can dynamically adjust power according to the application layer's processing requirements to provide higher efficiency. Power consumption can be as low as 25W, compared with the traditional X86 architecture based chips (such as Intel Xeon 2.5GHz), power consumption is one of 5 points, while the industry's lower power consumption based on the PPC cell chip and SPARC architecture UltraSPARC T1 chip power to 80W.





2 4D-UTM system of Blue Shield high efficiency virtualization





to adapt to the development of cloud computing, the implementation of network security applications efficient operation, the current Blue Shield shares of the network security products, based on the Blue Shield 4d-utm scalability function on-demand customization/on-demand expansion of the system design.





4D-UTM is 4 dimensional unified Threat Management, four-dimensional unified threat management. Unified threat Management (Unified Threat Management), unified terminal Management (Unified Endpoint Management), unified channel management (Unified Channel Management) and unified Strategy Management (Unified Policy Management) organically integrated into a whole linkage framework, which solves the problem that the network "point" (i.e. the host), "line" (i.e. boundary), "face" (that is, Security Policy Association Management) is difficult to unify the security specification, Through the linkage mechanism of private encrypted tunnels, a security defense system covering the whole network and equipment is formed, which makes the overall protection efficiency of the network greatly improved, and the whole network security protection is really achieved.





in the 4D-UTM system, the Blue Shield shares introduced the concept of virtualization, that is, the operating system and applications to build a virtual environment, a physical device based on customized functional modules into multiple devices, allowing users to not consider where the application resources, what form, how to install, And just call the program directly through the known path, on demand. In terms of network security requirements, customizable functional modules include the following 10 items:





from the cloud computing service level to understand how the virtual application module is obtained:





first, the IaaS layer realizes the virtualization of hardware resources and allocates, dispatches and manages the resources based on the virtual machine.





Secondly, the PAAs layer provides the service interface, realizes the basic and the common function, including the massive data storage and the backup, the massive security information collection, the analysis and the monitoring, the coordinated defense;





Finally, in the SaaS layer, the user through the Web service interface, in the form of network services to obtain all kinds of application-oriented software services, including the scheduled network security module, as well as cloud storage, cloud backup, Cloud Search virus, cloud firewall and other software services.





compared with the traditional way, the virtual function module of the Blue Shield shares has the strong business pertinence, reduces the hardware demand, greatly enhances the user's operation efficiency.





3) Comprehensive safety protection





Blue Shield shares "green cloud" product security protection function is mainly embodied in three aspects.





a security vulnerability scan of virtual machine software, virtual machines, management modules, Guest OS, and third-party applications in virtualized environments through cloud security scanning modules to ensure that the environment architecture of cloud computing centers is secure.





II ensures data security through cloud storage security systems, cloud backup systems, and cloud audit systems. The cloud storage security system adopts distributed file system, identity authentication, proprietary data encryption and decryption technology, to achieve the cloud storage of a large number of data application and management, at the same time solve the cloud storage System file transmission security issues, data node security protection issues, cloud services in the user identity and key centralized unified management, Multi-user batch audit and mass backup, and then through the virtualization integrated gateway to solve the cloud storage server Trojan Horse and virus defense problems, cloud data storage security protection issues, to achieve online storage, mass storage, secure storage three major functions.





Three is through the Blue Shield 4D-UTM Architecture Unified Strategy Management system UPM to the network each important information point, as well as the information equipment carries on the centralized unified policy management, the security linkage, realizes the dynamic security.








End Language





People's worry about it energy consumption leads to the concept of green computing, the rise of cloud technology provides a timely solution, but how to correctly guide the development direction of green cloud, improve market acceptance, and in-depth study of its technical bottom, is still the current global environmental protection under the major theme of a major lesson.





technology is a symbol of the progress of human history and civilization, environmental protection is the promise of the future of the Earth. Blue Shield "green cloud", let technology and environmental protection peers.
