Description
Technical field
The present invention relates to computer and network technologies, particularly relate to the software provider method based on cloud computing and system.
Background technology
Since Amazons in 2006 and *** propose cloud computing concept, 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: namely platform serves (Paas), namely infrastructure serve (Iaas) and namely software serve (Saas, Software as a Service).
In the past, people used software to be carry out the work of being correlated with by mounting software in PC or server.Like this, each machine needs to install a software.Some software prices are high must allow many users bear, and these softwares to be many users have to uses.So just there will be a lot of piracy software on the market, thus constitute the injury in a kind of interests of software supplier.Meanwhile, expensive copyrighted software constrains the use of user.These two kinds of situations are very unfavorable for the development of software industry, and the problems demand of generation solves.
Cloud computing technology appear as the approach solving the problem and provide and deal with problems.First, the service that cloud computing provides can make to calculate relevant service industry and become more specialized.User only need according to oneself need choose the software used required for oneself, and store memory capacity required for data, offer the account of oneself, pay corresponding service charge to computer center and just can enjoy service.Secondly, as the upgrading of software, computing platform, store dilatation, data security maintenance etc., only need service provider to concentrate and solve.Computational resource, storage resources, software resource can be made thus to be configured effectively and reasonably.If client need use cloud computing platform related service, sign in relevant cloud computing center (Chao Suan center, data center etc.).The client logged in can complete relevant operation as the computer of operation oneself.Where no matter client go to, data all at any time with quarter just at one's side, do not needed the too many thought of preparation expense for some data.
Saas is a kind of pattern being provided software service by the Internet (Internet), and user can buy software, but rents required software by network to software vendor, realizes the activity such as developmental research or management.Buy software relative to traditional user oneself, Saas cost compare is cheap, and the input that it can make enterprise or personal development study early stage reduces, and provides huge facility for medium and small, Personal development reduce up-front investment; Simultaneously it is also highly profitable for the utility ratio combated copyright piracy and improve copyrighted software.
But, based on the mass computing center of cloud computing and Saas, be also only in the conceptual phase at present.Existing saas mainly also rests in the popular application of fairly simple or low level, such as Email, collaboration platform, network teleconference etc., less demanding to safety, and the data that client stores is also very single.Require very high for some calculated performances to computing platform, and a large amount of calculated data can be produced and the user high for the security requirement of data, also not yet form standard and the governed pattern of maturation of practical application.In addition, if there is the same computing platform of the use of a large number of users in a computer center, the quality of service will certainly be reduced.If now computer center also has the computing platform of other free time available, then suitably can shift using the task of same computing platform.How to improve calculated performance and client data secure, Ye Shi computer center needs the direction of holding.
Known in sum, need to provide a kind of software provider method based on cloud computing technology and system, can computational be provided high for user and guarantee the mass computing center with many computing platforms of Information Security, by cheap Saas for medium and small, individual enterprise provide software service convenient, improve the utility ratio of copyrighted software simultaneously, thus provide healthy development environment for software industry.
