According to an IDG center for the country "which issues facing virtual extension" of the investigation and found that the ease of difficulty order, followed by technical problems (33%), capital costs (23%), currently there is no apparent demand (20 %), safety (15%). This shows that the technical, financial, security, storage virtualization is still in the development of the main difficulties in the process of maturation. Survey results show that the majority of the respondents virtualization maturity rather pessimistic view, only 14% thought that the technology is mature, and four percent of people believe that immature.
Survey, "worrying about the cost of adopting new technologies is too high," "no applications", "lack of maturity of the program and success stories," "there is no uniform standard platform for virtualization" and "concerned about security, do not want to host eggs in one basket, "" product prices "that have hindered wider application virtualization five bottleneck.
This article does not hides on display in, try on the current domestic virtualization symptoms of an in-depth "examination", "prick" "pouring cold water", and made humble opinion, hope the industry can sober self-reflection, proactive, positive response, for domestic virtualization continued bring healthy growth of beneficial warning.
Promote the use of five major virtualization bottlenecks
1, no uniform industry standard platform for virtualization and open protocols, increase user investment risk.
Currently providing virtualization solutions many companies, the market is no uniform objective criteria, various manufacturers of equipment for storage virtualization is basically a "entertain, every one in his administration," the state, so that manufacturers are now placed before the user solution that enables users to feel like Mangrenmoxiang, IBM has IBM virtualization, VMware has its own virtualization, Microsoft also has its own virtualization scheme, other companies, too, all that a life of its own way, so that people feel very confused.
Therefore, each manufacturer's products is difficult to integrate in the same environment, can not be compatible with each other, difficult to extend to upgrade, reduced flexibility of the system, allowing users to face from the "hardware siege" to the "virtual hardware siege" of the predicament. And because of the difficulty and the integrated management of servers, but also additional administrative overhead. Therefore, the current virtualization-related products, related standards do not define the final sound is an important constraint factors.
2, virtualization, there are considerable operational risks, as "too many eggs in one basket" may be pregnant with "one wing were damaged wing of a loss are" shell.
As we all know, virtualization is the disadvantage of a hardware node can not be mixed in with a different operating system, there is a problem if the system kernel, the server also had "implicated" of failure - a major server hardware failure only affect the services on this server, but if the server is running multiple virtual server, the problems, the risk more.
For domestic users, buy a server to come back into several different partitions to run different operating systems, different databases, different applications have hidden heart - if this server problem, all the systems are likely to the collapse of this downtime, and so the risk is no trivial matter.
Unless the server crashes before, the ability to quickly move to another virtual server for a new physical server. Furthermore, virtualization may also cause some physical environment, not the security risk, system-level virtualization technology may allow users to complete without the knowledge of hacking, virtual rights management and authentication into links increase new challenges. In addition, even if the management of physical servers reduces, but there are so many virtual servers require monitoring and management, also increased risk.
3, the cost is prohibitively high, impeding promote the use of virtualization technology.
Price, unit cost is the user application must be considered when building an important factor.
Present a framework for virtual environments million initial investment cost is about more serious was the only large-scale high-end users to endure affordable to the average SME can "play". So even if the vendors to educate business users how well virtualization, enterprises must carefully consider the cost of the technology. Cost is very important to consider the current cost, but also to consider the cost, including software upgrades, hardware maintenance and future ongoing costs of purchasing such a lot of money. In addition, SOA is the development of application management software virtualization best way, but will require substantial cost to renovate existing software, so only very strong ISV would do, leading ISV's enthusiasm is not high, and restricted The large-scale commercial deployment of the.
4, migration and management tools are still not mature enough, affect the spread of virtualization.
Many users of virtualization technology has been a growing recognition unit to switch the virtual data center, is most difficult to migrate. Because the data, information from the physical environment to a virtual environment is no longer as before the database migration from physical servers to another physical server, so simple, the difficulty of significantly increased, there may be "the opposite sex repulsive," but also may be a time-consuming and costly process, is facing many problems. In particular, transplantation and management functions of the remote more problems.
In fact, virtualization is not a 100%-compatible solution, it does not, and all applications or all of the hardware co-ordination, most of the virtual machine is a basic PC simulation environment, rather than application programs direct access to hardware resources , also a lot of migration and management problems.
5, virtualization technologies are not mature sound, not much to alleviate the workload.
The current virtualization technology can do hardware virtualization, application still can not do virtualization, resulting in system performance delay. According to expert analysis, assume a company a year ago with 10 physical devices, it can reduce the number of virtual technology to reform the 7 units. However, the company may be required later in the 7 physical device to run 24 virtual devices. The company need to manage the number of physical servers by 30% although the reduction, but it needs to manage the number of the operating system is likely to increase by 150% or so.
Break through the bottleneck of the four major virtualization strategy
Virtualization technology is a promising direction, but not a panacea to conquer the world, not snake oil, what are applicable. Domestic manufacturers must be virtualized, "pragmatic" one should actively absorb advanced foreign technology and ideas, so that foreign things serve China Chinese and Western, on the other hand should be based on existing technology and virtualization technology accumulation and the development of to combine the creativity, and how close to the needs of domestic customers to make a fuss, give full play to local features, advantage.
Strategy 1: From the establishment of "Experience Center" to start with increased publicity.
Virtualization is indeed a "very false" concept, so we must understand the application of user units, necessary to set up virtualization solutions and applications Experience Center, allowing users to "first Tiyan, buy after you" really feel the benefits of virtualization easy to use; also for domestic users, increase the publicity of various cases of successful application of virtualization, particularly in the case of domestic users and establish model projects the industry, allowing users to program unit to understand the significance of virtualization applications, role, application costs and possible problems and the next solution, to create a worry integrity applications. In fact, virtualization is not all users need, so let the user know what kind of unit in the end only need virtualization, application virtualization, what kind of application environment, the user program when using virtualization to create a "win-win and common prosperity" .
Strategy 2: Actively promote the application of virtualization technology and the creation of standards work.
Through the establishment of scientific authority performance storage technology assessment committee to develop a unified standard platform for virtualization, to break the barriers between storage devices to achieve better connectivity. It is worth mentioning that many companies now regard the "automation, standardization," as the highest state of virtualization or upgrade stage. If you want to virtualize real play, it must pursue the automation, standardization, virtualization push towards the direction of standardization, rather than every one in his administration went their own ways, can not access compatible, thus affecting the popularity of virtualization technology development. The automated, standardized, various manufacturers of related products to achieve seamless interoperability, so as not to cause performance slow down, downtime and other issues.
Strategy III: "Universal products, individual application" to leveraging virtualization market, high demand and rapid spread.
Through the provision of a large number of elements can be customized to meet various user-centric in the virtualization market demand, that gives a strong virtual products of generally used and based on this to meet the individual needs of users, from changing the demand Zhong Zhao Dao common, to find out there from the chaotic rule of virtual technology "universal, commercial," thus breaking the bottleneck of popular virtualization to achieve low cost, high success rate of construction of the purpose of virtualization technology.
