Description
Technical field
The present invention relates to the cloud computing technical field, refer in particular to a kind of system and method thereof of online customizing virtual machine mirror image.
Background technology
It is the centralized architecture (data center 1.0) of main body with the large-scale computer that the computer application pattern has experienced substantially, be the client/server distributed computing architecture (data center 2.0) of main body with the PC, be the service-oriented architecture of core (SOA) and with the Intel Virtualization Technology based on the novel framework (data center 3.0) of Web2.0 application characteristic.The differentiation of computer application pattern, Technical Architecture and realization characteristic is the historical background of cloud computing development.
Internet technology becomes the basis that ICT uses, and the internet, applications demand that emerges in an endless stream also requires the ICT theory to think deeply again and design.This change not only brings the update of ICT application platform, and brings ICT Application and implementation and commercial Model Innovation.The influence of this variation is so huge and distinct, to such an extent as to people can describe these new characteristic and phenomenons from a plurality of angles and visual angle.Although the notion of cloud computing and definition are a lot, study carefully its essence and still realize with professional network in order to satisfy the ICT application.For theoretical and the preciseness of discussing, give cloud computing more clear and definite and strict definition: cloud computing is under the framework of integrating, and the virtual resource platform of IP based network provides scale ICT the implementation of application.
The essence of cloud computing is the application under the network, by IP and the common structure of IT technology.From development point of view, the technology of " cloud " and target are processes that progressively develops.Such as, when the Web technology occurs, the blank at unified interface has been arranged with regard to the application characteristic that has possessed cloud computing.Along with the release that the maturation and the Web of the Intel Virtualization Technology on the server application platform unifies the interface, virtually move towards to combine with Web, make cloud computing can on the framework of an integration, unify realization.
Virtual is the term of a broad sense, is moving on the virtual basis rather than on the real basis typically referring to computing element aspect the computer.Intel Virtualization Technology can enlarge the capacity of hardware, simplifies the process that reconfigures of software.It is parallel that the Intel Virtualization Technology of CPU can single CPU be simulated many CPU, allows a platform to move a plurality of operating systems simultaneously, and application program can move in separate space and be independent of each other, thereby significantly improve the operating efficiency of computer.
Intel Virtualization Technology and multitask and Hyper-Threading are diverse.Multitask is meant a plurality of programs parallel running simultaneously in an operating system; And in Intel Virtualization Technology; Then can move a plurality of operating systems simultaneously; And all there are a plurality of program running, each operating system all to operate on the virtual CPU or fictitious host computer in each operating system; Come the equilibrium code runnability and Hyper-Threading is single CPU simulated dual CPU, the CPU that these two simulations are come out is indissociable, can only collaborative work.
Also to reach the software of virtual effect equally different with present VMware Workstation etc. for Intel Virtualization Technology, are huge technological progresses, are in particular in and reduce software virtual machine associated overhead and support operating system aspect widely.
Use the methods aspect deploying virtual machine such as maximum virtual machine manager Xen, KVM, QEMU to have nothing in common with each other at present in the cloud computing field; This situation disposes for cloud computing field cluster virtual machine environment and the large-scale application deployment brings challenges; Therefore; A kind of method and system need be provided, can unify online customizing virtual machine system image.
