Guosong Liu: China's leading cloud storage service provider

Guosong Liu: 1997 into the computer department of Tsinghua University, 2001 years after graduating from direct reading PhD, during which he served as a student counsellor and the Department of student leader. 2006 in Tsinghua Science Park Enlightened holding work, 2009 independent Entrepreneurship, and partnership founded Beijing Xing Yuzenko Investment Co., Ltd. Current Beijing Xing Yuzenko Technology Development Co., Ltd. General manager. Beijing Xing Yuzenko Technology Development Co., Ltd. is actually a young company, founded in 2009 to now only 3 years, the company team is also very young, more than 70 and generation, but this young company and the young people to find a new direction, grasp a future trend, They strive to become China's leading cloud storage service provider, providing security, privacy, convenience and high speed cloud storage services and products for the public and enterprise, contributing to the popularization of cloud storage applications and the promotion of social development. "Water wood Tsinghua": Now cloud storage technology has become a hot topic in the IT field, please introduce the global and domestic development situation in this respect. Guosong Liu: Technically speaking, cloud technology has fully integrated and applied the computing technology and communication technology such as parallel computing, grid, cluster computing, distributed computing and storage. Cloud concept launched, there are a lot of arguments about what "cloud" is, in fact, I think it is really difficult to judge from the technical, because in the cloud, all computing, transmission, storage units, all together, connected to the cloud from the acquisition of data and computing resources, but also for the cloud to provide resources. No matter which country, region, or even space these users are physically from, we can provide services as long as there is a need, and the customer does not need to care about the source and path of the information. I think from the application point of view, super large-scale, intensive management brought about by the very low unit cost and easy to expand and use is the core characteristics of the cloud. Conversely, small scale, separation, high cost is not the cloud. There is no doubt that the future of computing and communication is the world of clouds, for example, 15 years ago I bought a computer, playing DVDs will jump frames, because the computer's computing power does not reach the requirements of the movie, so I need to replace the higher performance of the computer. But in the cloud world, the "cloud" (server-side) computing capacity can reduce the ability to compute the terminal requirements, the cloud tube end of the structure so that very large amounts of data are hidden behind the scenes, and users use and care of the display work, only to complete the terminal. Cloud in the world, as long as the network cable, pay a certain fee, and do not need to care about the provision of services infrastructure platform, greatly reduce the personal IT facilities update and maintenance of the time and cost. The cloud is a service, web-based and large-scale computing technology for IT services. Many multinationals are already offering their cloud services, and many have already profited from this area, such as Amazon, Google, EMC, Cisco, and domestic IT leaders such as Baidu, Huawei, Ufida, Ali software and major operators. Due to the limitations of infrastructure such as network bandwidth, cloud applications in China are notSo fast to go into thousands of households. Now it is more widely used by the government, the enterprise uses the private cloud or called the exclusive cloud. Various internet organizations are also moving some non-critical applications (such as: Non-secret Web sites, backup, training, etc.) gradually migrated to the public cloud system, and those who have high data security requirements, must run in the enterprise firewall applications are more inclined to private cloud system. Cloud applications are divided into cloud computing and cloud storage, which, in contrast, may be an application that can travel earlier into millions of households. Ordinary people will not have such as weather forecasts, oil exploration, such as large computational requirements, more demand is such as the lack of disk space, the need to organize office and personal computer or synchronization, in this respect, cloud storage will be a more extensive application. Users in the cloud has a storage space, such as foreign Dropbox, the domestic Dbank, Jinshan, Sohu, NetEase and other portals launched the network disk, the background technology of these nets is cloud storage. "Water Wood Tsinghua": Please brief introduction of the company's main business and the main purpose of the product, who will use the company's products? Guosong Liu: Our core product is actually a cloud storage engine, now mainly to do two aspects of service, on the one hand is to provide enterprises and institutions of cloud storage, backup, disaster recovery services, on the one hand, to provide personal network storage and sharing services. Now the company operates a cloud storage System-99 disk, already has nearly million registered users, thousands of T storage space, more than 200 million of the files are stored on our system. In addition, our servers are distributed in six cities, connecting telecom, Netcom, education network of more than 10 data centers, can provide users with the fastest access services, multiple backup provides a high degree of security mechanisms. At the same time our long disk client, can provide users with hardware encryption data, similar to the bank U shield level of high data confidentiality. At present, according to our statistics, the users of cloud services, white-collar workers, business people and students are mostly users, because they accept new things more ability, and often have the demand for mobile office, our products are mainly facing such customer groups. "Water wood Tsinghua": Cloud computing related technologies are currently in the promotion of concepts and improve technology, supporting services, the foundation stage, most potential users of cloud storage security, reliability, stability doubts, Xingyu technology companies in this area do a better business, You and Tsinghua University jointly developed with independent intellectual property rights of the cloud system to better solve the problem of security and reliability of cloud storage, please introduce compared with other similar products, the system's technical characteristics, the use of bright spots, as well as the company to build the confidence of the user to do the work. Guosong Liu: Xing Yun system is Xingyu technology and Tsinghua University jointly developed a new generation of environmental security mobile cloud computing platform, is 99 disk background cloud storage core. Xing Yun system based on virtualization and cloud storage and other core technologies, providing network, computer, mobile storage integration solutions. Xing Yun System has two technical characteristics, one is centralized in the terminal virtual desktop, provides a safe use environmentThe second is the secure communication mechanism based on distributed system, which provides a fast and secure data storage channel. China now do a lot of network plate, for example, Huawei, Jinshan, 115, cool disk and NetEase, their services have their own characteristics, but the more common problem is to upload through the client or Web page download, only rely on 10-bit software password encryption, which can not guarantee the safety of the terminal use of the environment, There is no guarantee of data security. Just think, if let the user do not use U shield, but use net silver to do large amount of fund management, the user certainly does not trust, this is too easy to be hacked to crack. The network storage is the general trend, but the security, the speed is the service provider needs to solve the core question, is also the user most concerns. For these two issues, our security certification system can be installed on U disk, removable hard disk or other solid-state hard drive. The user who inserts this disk into the computer pops up a personal desktop that is commonly used in software that is separate from the software I use for this computer. That is, no matter where you go, just plug in the device, it is your personal work environment, we provide the space is the cloud storage space. Mentioned earlier, our server covers Netcom, telecom, Education Network, no matter where the user access to our 99, the system will have a routing algorithm, the nearest to find a data center to provide storage services for him. Users use our 99, the first will pop up a personal desktop, on this desktop running stock software, Office software or send and receive email, completely in our controllable environment, will not be used in this computer left traces. This 99 disk is a familiar office environment, but also your personal cloud storage data is a key, but also the data upload download cache, through our cache and storage system structure innovation, effectively solve the security and speed of two major issues. "Water wood Tsinghua": In the research and development process, have encountered any problems? How to solve these problems? Guosong Liu: Security has always been a problem for us, through several methods to enable our system to achieve a high degree of security. First, file encryption, in the terminal cache to the file encryption, then cut, a file by size cut to more than 10 to hundreds of different, then do a random sort, upload to the routing server, the routing server to determine where these files fragments to which nodes, so that both maintain security and maintain data redundancy. File encryption is the use of our improved data encryption algorithm, the current encryption algorithm after years of application and improvement, practice has proved to be very safe and reliable, effective guarantee of data and passwords in the transmission process security. Another is the disaster recovery backup mechanism, our server automatically and real-time data image to the geographically remote backup server, because we have to consider the background server some storage hard disk may be bad, even if the user's information will not be lost, this is our solution to the security of the document a process. The greater the redundancy means that the cost of your resources and hardware isLarger, our architecture can minimize this cost, so wherever we go, we can present the data in the cloud space to the user. "Water wood Tsinghua": Xingyu technology company was founded only two years, has applied for 9 invention patents and access to 6 software copyrights, please talk about the company's long-term planning goals and your work experience. Guosong Liu: Our long-term planning goal is to continuously accumulate technical advantages, and strive for more users to use our system, and constantly optimize and improve to achieve our business objectives. Now the biggest problem is still the reliability of the problem, first of all, we have to reassure customers, in the marketing process, from the technical point of view of the user publicity. This is like Taobao just launched Alipay, with few people, but now use Alipay has a lot of people, as the company slowly grow, the user's trust will also increase. Trust mechanism needs to be cultivated slowly, market development will encounter some difficulties, and because of this, do cloud storage manufacturers are trying, but now there is no real mature application. Now our main direction is to promote the personal cloud storage services, this process may be more difficult and long stage, to cultivate the user's consumption habits, while cultivating the user's confidence in the market. 99 Disk
