Description
Technical field
The present invention relates to computer and network technologies, the software that relates in particular to based on cloud computing provides method and system.
Background technology
Since Amazon in 2006 and google propose the cloud computing notion, started IT revolution of new generation, cloud computing thought becomes more and more popular, and the paces of its technical development and application are also more and more faster.Present cloud computing technology comprises three aspects: platform is promptly served (Paas), infrastructure promptly serves (Iaas) and software is promptly served (Saas, Software as a Service).
In the past, people to use software be the work of being correlated with through install software on PC or server.Like this, each machine all need be installed a software.The software price height that has must let many users bear, and these softwares are many users must not be obsolete.So just a lot of piracy software can occur on the market, constitute thus to the injury on a kind of interests of software supplier.Simultaneously, expensive copyrighted software has restricted user's use.These two kinds of situations are very unfavorable for the development of software industry, and the problem of generation needs to be resolved hurrily.
Cloud computing technology appear as the approach of dealing with problems that provides that addresses the above problem.At first, the service that provides of cloud computing can make that calculating relevant service industry becomes more specialized.The user only needs to choose according to the needs of oneself software of own required use, and the needed memory capacity of storage data, offers the account of oneself, pays corresponding service charge to computer center and just can enjoy service.Secondly, as the upgrading of software, computing platform, the storage dilatation, data security maintenances etc. only need the service provider to concentrate and solve.Can make that thus computational resource, storage resources, software resource are configured effectively and reasonably.The client signs in to relevant cloud computing center (ultra calculation center, data center etc.) and gets final product if need to use the cloud computing platform related service.The client of login can accomplish relevant operation as the computer of operating oneself.Where the client is no matter go to, and the data that institute will use all at any time with carving with regard at one's side, need not be the too many thought of preparation expense of some data.
Saas a kind ofly provides the pattern of software service through the Internet (Internet), and the user can buy software, but rents required software through network to software vendor, realizes activities such as developmental research or management.Buy software with respect to traditional user oneself, the Saas cost is cheaper, and it can be so that enterprise or personal development study the input in early stage to be dwindled, for medium and small, individual's foundation reduction up-front investment provide huge facility; Simultaneously it also is highly profitable the utility ratio of copyrighted software for combating copyright piracy and improving.
Yet,, also only be in the conceptual phase at present based on the mass computing center of cloud computing and Saas.Existing saas mainly also rests in the popular application of fairly simple or low level, Email for example, and collaboration platform, network teleconference or the like, not high to safe requirement, the data of client's storage is also very single.Very high for some to calculated performances requirement of computing platform, and can produce great amount of calculation data and the user high to the security requirement of data, also do not form the standard and the ripe governed pattern of practical application as yet.In addition, if the same computing platform of use of a large number of users is arranged, will certainly reduce the quality of service in a computer center.If this moment, computer center also had other idle computing platform available, then can the task that use same computing platform suitably be shifted.How improving calculated performance and customer data fail safe, also is the direction that computer center need hold.
Can know in sum; Need provide a kind of software that method and system are provided based on the cloud computing technology; Can the mass computing center with many computing platforms that computational is high and guarantee Information Security be provided for the user; Through cheap Saas is that medium and small, individual enterprise provides software service convenient, improves the utility ratio of copyrighted software simultaneously, thereby the healthy development environment is provided for software industry.
