The industry's controversy over cloud computing has shifted from cloud computing to cloud computing, but there are still many misconceptions. A few days ago, a large number of experts to discuss the matter, the landing of cloud computing, not all applications are suitable for virtualization, and the scale of the use of the cloud, good network conditions are essential.
do not virtualize for virtualization
generally believes that a feature of cloud computing services is that it is divided into virtualization technology and provided to users on the basis of user needs. However, Li Huewei, general manager of China Aviation Service outsourcing services, said that virtualization is only part of cloud computing and not virtualized for virtualization.
in 2008 began migrating to X86 and virtualization platforms, involving nearly 60 businesses, which took about a year to complete migration to a virtualized platform. But Li Huewei says that virtualized data centers include not only virtual machines, but also many X86 physical entities, not all services throughout the migration process, or not all applications are ideal for virtualization.
Wei further that Avic is more traditional, including the Web layer, application layer and database layer of the three-tier architecture, Web layer 100% virtualization, application system can only migrate percent, a lot of third-party tools, from the original server to the virtual environment, the operation will become very slow; So far, the 90% database is not running in the virtualization platform, where 20% of the database is running on the X86 server, more than 70% of the data is still running on UNIX.
Orange Business Services China's chief technology officer Liu Xin that the process of migrating to cloud computing is not just a technical issue, there are many aspects to consider, the need to integrate with traditional it architectures, some systems that are not suitable for virtualization or distributed deployments, and some applications cannot be virtualized. In other words, two sets of systems are coexistence.
, chief engineer of the Telecommunication Research Institute of Industry and Information technology, Lin Tao that the cloud will use virtualization technology, but he points out that the current technology for server virtualization is immature, especially since standards have not yet been established, and that technology between vendors is not compatible with each other.
A few days ago, when VMware provided a free VMware accept software to support the conversion of Microsoft's virtual machine format to VMware format, Microsoft introduced a software named Microsoft Virtual Machine Accept, Enables smooth conversion of VMWare virtual machines and virtual hard disk file formats to Hyper-V virtual machines and Microsoft virtual hard disk files.
However, because of the exclusivity of CPU hardware-assisted virtualization technology, users still need to choose between using Hyper-V (the upcoming Windows 8 built-in) and VMware virtual machine software.
Network is the base of cloud computing scale development
as the core of IT infrastructure, the network played the main role of interoperability, integration, 0 bearing. Lin Tao said that the cloud unit (the basic concept of cloud formation) needs to be connected by a high-speed broadband network, so broadband networks are the basis of the cloud. Huiling, deputy Dean of China Telecom's Beijing Research Institute, said the network capability is the basis of cloud computing scale development, without broadband network, cloud service is not.
Thus, cloud computing has brought tremendous changes to a new generation of networks and data centers.
However, Lin Tao pointed out that the current cloud computing network is quite immature, not to mention the broad sense of the network is simply impossible to use, at least the domestic network, used for cloud computing is not available, even if your data center network, this network is quite immature. If you hang up 10,000 servers, you can see which websites support it. So he thinks that technology is available, but it's all in the early stages of development.
H3C Cloud Computing business Minister Wu Jian also said that in the real cloud deployment process, servers and storage in the IT infrastructure are not too much of a problem, but the network segment can be a big challenge, or it is likely to be a bottleneck, with 50% of the problems appearing on the web, This is the problem that they discovered after they actually deployed the cloud computing agency.
Although the network bottleneck of people, are from telecommunications into the field of cloud computing, but cloud computing if the scale of application, the Network Foundation is really a problem that needs to be considered objectively.
Private cloud does not necessarily build
in China, because of security considerations, Oberyun first Private cloud view by users, Microsoft and other manufacturers also use private cloud as the main strategy of China's cloud computing market.
generally believe that the private cloud is built inside the enterprise, but the Chinese National Securities Information Technology Department general manager Yianyang pointed out that the concept of private cloud is often easy to confuse.
Yianyang says private clouds are not necessarily built within their own company, some are placed on external service vendors, and the cloud used specifically for an organization is called a private cloud.
Yianyang also believes that there will be a situation in the Alliance private cloud, in the United States to do some community cloud, there are common interests of organizations, they find the appropriate service providers to build a private cloud of the alliance, the organization to provide the corresponding professional services. Yianyang that this form is from the corporate private cloud to the road to public clouds.
information experts, Zhiyuan Cooperation Institute Dean Liu Guaquan pointed out that the use of the cloud, should be idle computing resources to use up, are built is a misunderstanding, the cloud should be distributed deployment, centralized use, specialization of division of labor.
future toward Big Data
Lin Tao that the physical entity of cloud computing is the data center, Huiling also said that the data center is the core of cloud computing scale development, Yianyang believes that it is necessary to improve the enterprise-level data center, if there is no integration between the system to put into the cloud, the price is very large. From the perspective of the securities industry, Yianyang that it can guide the change to data aggregation integration, to avoid the coordination of functional departments in the industry problems.
for some companies, the data center is not perfect. Yianyang further points out that with the landing and deepening of cloud computing, the entire enterprise-class data center must evolve into a social data center. From a semi-closed state to a fully open model. Such a shift would have a very large impact on the business architecture, the management structure and the technical framework. Therefore, how to deal with unstructured data, how to deal with massive data, how high-speed to deal with these data, we have to face large data three relatively critical latitude.
Li Huewei said that the data warehouse platform of the OLAP system, parallel processing capacity is more important, equivalent to multiple machines into a machine in use, this is the cloud itself a technology.
However, on such platforms, as the number of growth, the data loading cycle is getting longer. Therefore, the aviation letter also faces the request of the diversity of Internet data, the massive data processing, the unstructured data processing, this kind of high complexity processing, moreover in the Intelligent Analysis request quick response, faced these challenges, the system simply cannot cope with the deep level high agility this kind of visit, therefore needs to develop the big data development strategy.
