【摘要】:云計(jì)算可以把企業(yè)提供的服務(wù)通過網(wǎng)絡(luò)提供給用戶。因?yàn)楝F(xiàn)有的云架構(gòu)缺乏云服務(wù)組合和部署的中間件層,所以本文提出基于軌道圖靈機(jī)的云服務(wù)部署模型。這個(gè)云服務(wù)部署模型使按需云服務(wù)部署更加方便和快速,并實(shí)現(xiàn)了一個(gè)基于云計(jì)算的中間件動(dòng)態(tài)服務(wù)部署(CMCD)原型。 云服務(wù)部署模型包括云服務(wù)搜索引擎模塊、云服務(wù)組合模塊和圖靈機(jī)構(gòu)造模塊。云服務(wù)搜索引擎模塊是一個(gè)支持匹配算法多標(biāo)準(zhǔn)的云服務(wù)的搜索引擎。它能夠搜索滿足以下3方面要求的云服務(wù):(1)功能要求,(2)技術(shù)要求,(3)費(fèi)用要求,為了進(jìn)一步提高搜索結(jié)果的準(zhǔn)確性,我們設(shè)計(jì)了一個(gè)云本體。云本體包含了一組云的概念,和這些概念的個(gè)體以及這些個(gè)體之間的關(guān)系。云本體是用于確定相似云服務(wù)的依據(jù),基于云本體的相似云服務(wù)推理方法包括三種(1)概念相似度推理(2)對(duì)象屬性相似的推理(3)數(shù)據(jù)類型的屬性相似推理。在現(xiàn)實(shí)中,云本體論有效的解決了我們?nèi)绾味攘吭品⻊?wù)提供商提供的云服務(wù)之間的關(guān)系即相似度的難題。在云服務(wù)的組合上,我們使用有限狀態(tài)機(jī)(FSM)規(guī)定其調(diào)用序列,,并且基于一種改進(jìn)的修剪算法來創(chuàng)建云服務(wù)組合樹。在其云服務(wù)組合樹中可以找出所有的可執(zhí)行的路徑,然后用一個(gè)簡單的加權(quán)技術(shù)用于選擇最佳的路徑即所要部署的云服務(wù)。 圖靈機(jī)構(gòu)造模塊主要是從云服務(wù)提供商宏觀層面進(jìn)一步對(duì)云服務(wù)的部署進(jìn)行控制。CMCD說明了動(dòng)態(tài)云服務(wù)的部署可行性。CMCD中間件使用圖靈機(jī)的數(shù)學(xué)模型,實(shí)現(xiàn)動(dòng)態(tài)云服務(wù)部署。實(shí)驗(yàn)說明基于圖靈機(jī)的云服務(wù)部署算法在普通云服務(wù)功能方面有較好的性能,并且部署成功率非常高。
[Abstract]:Cloud computing can provide services provided by enterprises to users through the network. Because the existing cloud architecture lacks the middleware layer of cloud service composition and deployment, this paper proposes a cloud service deployment model based on track Turing machine. This cloud service deployment model makes on-demand cloud service deployment more convenient and faster and implements a cloud-based middleware dynamic service deployment (CMCD) prototype. Cloud service deployment model includes cloud service search engine module, cloud service composition module and Turing machine construction module. The cloud service search engine module is a search engine that supports multi-standard matching algorithms for cloud services. In order to improve the accuracy of search results, we design a cloud ontology. Cloud Noumenon contains a set of cloud concepts, the individuals of these concepts and their relationships. Cloud ontology is the basis for determining similar cloud services. The reasoning method of similar cloud services based on cloud ontology includes three kinds of concept similarity reasoning (2) object attribute similarity reasoning / 3) attribute similarity reasoning. In reality, cloud ontology effectively solves the problem of how to measure the relationship between cloud services provided by cloud service providers, that is, similarity. In the composition of cloud services, we use finite state machine (FSM) to specify its calling sequence, and create a cloud service composition tree based on an improved pruning algorithm. All the executable paths can be found in its cloud service composition tree, and then a simple weighting technique is used to select the best path, that is, the cloud service to be deployed. The construction module of Turing machine mainly controls the deployment of cloud service from the macro level of cloud service provider. CMCD illustrates the feasibility of dynamic cloud service deployment. CMCD middleware uses the mathematical model of Turing machine to implement dynamic cloud service deployment. The experiments show that the cloud service deployment algorithm based on Turing machine has better performance in the common cloud service function, and the success rate of deployment is very high.
