Small meeting to explore cloud computing

According to Xiaobian know, recently Guidu Hotel in Shanghai held a "cloud forward - Symantec cloud computing seminar." Zheng Weimin, Director of High Energy Institute of Tsinghua University and Dr. Liu Lifeng of Network Development Department of Jiangxi Telecom attended the meeting. Xu Qi, director of IT and New Business Planning Institute of Jiangxi Posts and Telecommunications Planning and Design Institute, Mr. Mao Lifeng, senior technology manager of Symantec Eastern Region, Mr. Lin Yumin, a senior information security consultant of Tieke, attended the meeting and conducted in-depth exchanges and discussions on Symantec's technology application in cloud computing and the value that Symantec Cloud Computing brings to enterprises and users.

Please tell Professor Zheng in the end what is "cloud", why do we need "cloud"?

Zheng Weimin, director of Tsinghua University's High Energy Institute: cloud computing has been very popular in the recent two years. Among them, the first is infrastructure services, the second is platform-level services, and the third is software-level services. A few years ago we call it grid computing, cloud computing in recent years. What grid computing and cloud computing have in common is that they provide easy web services for tasks through resource sharing systems, emphasizing virtualization. We use the technology is distributed processing technology, this grid and cloud computing is the same. The difference is that the grid emphasizes the omnipotent supercomputer. A few years ago I did a grid computing, Tsinghua University has a computer, Peking University has a computer, Shanghai Jiaotong University, Guangdong also has. Four computers are connected via a network, providing you with a service that handles high-performance computing in parallel. However, the current cloud computing is from the commercial mode of operation to provide services. The two calculations provide different perspectives of technology.

Now generally think of "cloud" there are two main categories, one is a public cloud, one is a private cloud. Private Cloud refers to the cloud computing platform that is used by only one organization or company. The common cloud refers to putting the computing platform on the Internet for everyone to use. Cloud computing is the computer, memory, software on the "cloud", submit a request, "cloud" on the computer, memory, software will retain your request. Here I give two examples, take a look at Tsinghua cloud computing platform.

How to meet the different requirements of different users? This is the service. We have provided a "cloud", this "cloud" is specifically for storage, you need to store the content on the "cloud" on it. According to different users on different memories, different numbers of hard disks, different operating systems, different runtime requirements, automatically configure and run. Perhaps in the past can only meet some of the requirements of users, but now different users are able to meet the different needs. Cloud computing is not to buy a computer, do not buy memory, do not have to buy software, "cloud" can provide you with the environment, and ultimately solve the problem.

Moderator: From a technical point of view, now the changes in the IT environment prompted us to think about cloud computing such a topic?

Mao Lifeng: From the perspective of operators, cloud computing entry point, and its business-driven what? We can from both internal and external perspectives, first of all, as we in the enterprise with the increasingly complex needs of IT, our business processes are also based on the above IT equipment, we have a very large demand for IT, As more and more businesses and IT architectures become more complex, we now urgently need a means to consolidate IT resources. Formerly a business platform, not an isolated business platform, the need for a host, the need for a backup system, the equivalent of a channel of information, then how to use effective means to integrate IT resources? We found that it is very sudden and very sudden for some businesses. For example, our SMS business is very large in the Spring Festival or New Year's Day when we send New Year's messages, but the sending volume of ordinary SMS is not very large. In order to cope with the short period of peak, we put forward the concept of low cost and high efficiency in our enterprise. We have to use good means to integrate resources. Cloud computing provides us with a solution.

From the outside of the enterprise, we have proposed to innovate the business. Just now, Professor Cheng talked about some business models and some cases of cloud computing. I think it is possible to give SMEs some of our business or provide our clients with cheaper computing rentals or storage Of the rental, which is not the same with our original idea, before we are hosting the way, and now with cloud computing, this is a change in business model, but also the concept of innovation. There is also an external side, just said PPT and photos can be put in the cloud, you have to visit will go through the network, for example, I do not have a laptop, my phone can be accessed, so that customers increase the network demand, so that Resources into the terminal, through the network to access the terminal, thus stimulating the development of the network, which for our business is also a new business growth point. Therefore, we have two aspects to be explored in this area.

Moderator: Next, we ask Dr. Liu Li-feng, companies need what kind of "cloud", "cloud" can bring what kind of help for the enterprise?

Dr. Liu Lifeng, Department of Network Development, Jiangxi Telecom: The mobile business support system has been developing for many years and has been around for a long time since 2001. Such a long time business support system is also accompanied by changes in the complexity of the business, the increase in business types and the growing number of users. On this basis, the relationship between business systems and internal interdependence is more and more complicated. The previous idea of ​​supporting the system platform was to centralize users, computing, and data, which increased efficiency while lowering operational costs. As the system continues to evolve, we find that larger concentrations cause more problems, such as reliability issues such as investment costs and operating costs, such as the impact on the entire business when switching systems. All kinds of problems are constantly emerging and we hope we can solve these problems well. Now it looks like Symantec cloud computing such a platform, such an architecture can well help us solve the problems encountered.

Moderator: Cloud computing development prospects and the challenges faced?

Xu Qi, Director of IT and New Business Planning Institute, Jiangxi Posts and Telecommunications Planning and Design Institute: Chinese users are not paying more attention to cloud computing than western countries such as Europe and the United States because China is facing a very high demand for energy and environmental protection and energy conservation. Therefore, challenge. The development of China's business in these years is very rapid, which has brought some support to the IT business. In summary, cloud computing actually has many advanced technologies and concepts that can help Chinese enterprises to solve more realistic problems.

Lin Yumin, Symantec senior information security consultant: a credible "cloud" will be users. Symantec hopes to provide viable and reliable cloud services throughout the "cloud" strategy and to help users build viable and reliable "clouds." There are several ways cloud computing can protect data security: 1, you can use storage technology to prevent other customers to steal. 2, to take the encryption technology. Symantec is developing storage-related user key management to protect the data of these users from being compromised. 3, management process. Whether to provide quality cloud services is the key to the success of cloud service vendors.

Moderator: Finally, please Mr. Lin Yumin to share Symantec's cloud computing strategy and application examples.

Lin Yumin, Symantec senior information security consultant: Wan always mentioned why Symantec is a security vendor, but here to talk about "cloud." Symantec has long been doing the concept of "cloud", research and development also do related applications. Share with you the following points:

First, cloud technology has changed people's lives. Cloud computing has brought new business models. Previously on the phone navigation software is to buy a traditional software to install a CD, now as long as Google can connect to navigate, to different countries do not need to download and install new navigation software. This can significantly reduce costs, because only the use of the "cloud" will pay. Navigation software is updated once a year, with cloud computing can be updated at any time. Cloud computing has brought a new computing model, many companies bought so many servers, so much storage, is not it all used? If you only need to buy storage space, this can save a lot of operating costs. The data above the "cloud" is passed from the traditional structured data to the unstructured data. There are many benefits to the "cloud," which are agile and flexible and have a low unit cost that can provide different service combinations for different services.

Second, about cloud computing strategy. Symantec is currently the world's largest cloud storage and cloud security software service provider, we provide a considerable number of "cloud" related services. 1, to provide software-level services. 2, whether to provide public cloud or private cloud providers, can have the original user interaction and connectivity. 3, Symantec provides cloud computing infrastructure and related software to help "cloud" providers and service providers to build the entire cloud computing technology platform.

Third, from the example of Symantec Cloud Computing, the best known is the cooperation with Amazon. Amazon is a well-known cloud computing service provider. Symantec assists Amazon in providing public cloud services and the corresponding infrastructure. First, to help Amazon cloud computing server to provide anti-virus services; the second is to help Amazon do virtual storage. Users do not need to do any installation and changes.

Fourth, about Symantec cloud security technology and services. Symantec uses cloud technology to credit global websites. There are three traditional ways, one is through "crawlers" to see if these sites contain malicious code. Second, if a virus can be directly fed back to our "cloud" above, if there is information released to know that these files are problematic. The third is based on the downloaded file name and signature and URL, so that managers better analyze the problems encountered. We are using two-way interaction to provide the relevant security. In addition to PC-side security, we also provide the defense mechanism of the cell phone, which is also achieved through the "cloud" approach.
