The indispensable relationship between cloud and virtualization

Cloud computing applications seem to be tightly linked to the construction of enterprise-class data centers and virtualization technologies. From the perspective of virtualization, software defines the concept of data center, from storage, network to desktop, fully affirmed the relationship between cloud and virtualization.

For the Enterprise data Center to build a virtual platform to achieve the "cloud" application of the problem, an unnamed professional and technical people gave a negative answer, the reason is the good faith-oriented social environment difficult to achieve is the first problem. In fact, this skepticism in the domestic majority of enterprises in the information technology pervasive.

However, in the integrity of the system is not formed, the laws and regulations are not sound, also can not block the industry's demand for cloud service applications. This can be from E-commerce enterprises, finance and other industries can be confirmed.

The rise of domestic cloud computing comes not from the internet's heat, but from the private cloud of traditional data centers. For users to build a private cloud platform, the implementation of self-service, there is no data privacy disclosure problem. There must be privacy issues when private clouds are held to the public cloud platform. This depends on the whole society must establish the integrity system. However, the formation of good system and the development of practical application of the market synchronization, the two must go through a step-by-step process.

Software runs through the data center

"Software definition data Center" concept mainly refers to the data center to achieve a full virtualization, but the actual number of data center servers can not carry hundreds of hundred. Today users are increasingly demanding virtualization capabilities, from a single to 2, 4, 8, up to 32, and memory to 1TB ... The application load that a single virtual machine runs is increasing.

The traditional industry application design direction is vertical expansion without horizontal expansion, it means that the load needs high-performance computing to deal with. In fact, the hardware into the high performance of large hardware, in the application layer do a lot of distributed processing, but can not be implemented in the underlying hardware, after all, the traditional industry based on it communication between the different computing equipment interoperability challenges.

The new trend of software development is to solve the increasing application load problem through the distributed design of software system.

Open source through private and public cloud boundaries

How to choose between two cloud models of traditional enterprise data center virtualization and Internet Data Center virtualization, Zhang Zhenlen analysis, cloud computing originated from the Internet, internet companies are using a highly customizable open source Linux platform, while traditional enterprise data centers using minicomputer, mainframe, the use of Oracle, Databases such as SQL Server. The biggest difference between the two is the origin of "grassroots" and "nobility".

From the Internet public cloud model generally serves the public, including the general end consumer and enterprise users. The data center of Internet Enterprise is a large number of software engineers owned by it, and it has been optimized by precipitation for many years to form the platform of not duplicating. That's why Amazon, Taobao and other enterprises in the high load can also continue to use the original computing platform, the main reason for its cloud platform at the beginning of the use of distributed (horizontal expansion mode) of the design concept, the use of cloud computing methods can not change the hardware platform on the basis of a good load of multiple applications.

Although it vendors already have sophisticated solutions that can serve enterprise-class users, they need to constantly incorporate the Internet Cloud application to help build cloud applications in traditional enterprise data centers built on standardized hardware it devices.

In fact, in the industry's mainstream UNIX, it runs on the application and load utilization is very low, even the user's utilization rate of less than 0.5%. To reduce this huge waste, the X86 platform can be used.
