Description

A kind of cloud computing resources of virtual machine is used charging method

Technical field

The present invention relates to cloud computing resources administrative skill field, especially a kind of cloud computing resources of virtual machine is used charging method.

Background technology

Cloud computing (Cloud Computing) is the new term be born in 2007, still there is no generally acknowledged definition at present.Cloud computing is a kind of business computation model, on it forms calculation task branch resource pool at a large amount of computers, makes the user can obtain as required computing power, memory space and information service.And cloud computing operating system is the holistic management operation system on cloud computing backstage, it refers to that framework is in the underlying hardware resource such as server, storage, network and single-set operation system, middleware, the underlying hardware of database basic software management magnanimity, the cloud platform total management system on soft resources.

IAAS: some companies of giving provide IT infrastructure, or the IT infrastructure of some companies of telemanagement, and this accounts for a very large part in the current business of cloud computing manufacturer, so it need to expand in cloud.This may mean that just one of telemanagement operates in the privately owned cloud in client's oneself data center, if so, that and do not have now what difference.Also may mean and will provide infrastructures or provide the provider of cloud service to provide infrastructures to those to the client.Perhaps, also may mean directly and provide multiple cloud service of renting form to the various companies beyond cloud computing manufacturer.

Virtual machine refer to by software simulation have the complete hardware system function, operate in a complete computer in complete isolation environment.It is the groundwork unit of providing infrastructures under the IAAS pattern, and the cloud computing service commercial city of main flow is to provide service with the virtual machine form, and virtual machine is the abstract of material resources, and for the user, it is the complete machine that comprises CPU, internal memory, hard disk etc.

Along with the cloud computing technology development, different cloud computing business models occurred, also be pregnant with a lot of successful cloud computing service business, the cloud computing platform pattern of Amazon is comparatively successful, embodied the main flow method of service of cloud computing as IAAS, for the user provides virtual machine service.

External large-scale cloud computing service business has released charging method separately, Amazon will rent example be divided into as required use, stock example and retain three kinds of examples, the charging method of every kind of example is characteristics separately all, are used in different use scenes.Microsoft provides two kinds of basic pricing models: a kind of " consumption " selects the resource that allows the user be actual use to pay; The selection of another kind of " payment on term ", provide the price of discounting according to the use contract of 6 months.The charge details of Microsoft relates to computational resource, storage resources and number of processes.

Overview, although form and the details of external cloud computing charging method differ, be all to go out to send computational costs from computational resource and storage resources basically, gives on this basis certain preferential or discount and attract the user.Their charging method advantage is comparatively comprehensive, and shortcoming is comparatively complicated.
