【摘要】：云計算作為目前IT業(yè)最流行的領(lǐng)域之一,是一種嶄新的計算模式。云計算逐步實現(xiàn)了從概念走向?qū)嶋H,越來越貼近人們的日常生活。人們在不知不覺間已經(jīng)在享受“云”帶來的便利,然而,人們在享受便利的同時,也需要承受“云”帶來的不便。 基于故障模型的軟件測試技術(shù)在多年的研究和實踐中獲得了快速的發(fā)展,成果也很顯著。隨著云計算的廣泛應(yīng)用,故障問題隨之產(chǎn)生。越來越多的研究開始針對云計算中的故障檢測,并出現(xiàn)了很多故障檢測方法來減少云計算中的故障,但是還存在一些問題：(1)傳統(tǒng)的軟件故障模型并不能夠完全涵蓋云計算中的所有故障,因此,在故障檢測過程中,云計算中的一些故障可能不能被檢測出來。(2)有些故障檢測方法中使用故障特征作為指標(biāo)來檢測故障,但故障和故障特征之間的關(guān)系定義不明確。 為了解決以上問題,本文將故障模型、故障特征和云計算中的故障檢測結(jié)合起來,首先建立云計算中的故障模型,然后設(shè)計檢測方法來對云計算中的故障進行檢測,希望在不斷測試的過程中完善所建立的故障模型。在發(fā)揮故障模型優(yōu)勢的同時完成云計算中故障的檢測,主要完成以下工作： (1)為解決云計算中故障種類多、變化快的問題,在研究軟件故障、故障模型的基礎(chǔ)上,結(jié)合云計算的特點,提出了云計算環(huán)境下的故障模型,分別從四個角度對云計算中的故障進行分類,建立云計算下的故障模型； (2)定義了故障和故障特征的關(guān)系,將云計算環(huán)境中出現(xiàn)的故障和故障特征關(guān)聯(lián)起來； (3)針對提出的云計算的故障模型和故障特征模型,提出了一種基于云計算的故障檢測方案； (4)設(shè)計并實現(xiàn)了一個云故障檢測系統(tǒng),并通過大量實驗驗證了方案的正確性和系統(tǒng)的有效性。
[Abstract]:Cloud computing, as one of the most popular fields in IT industry, is a new computing model. Cloud computing has gradually realized from concept to reality, more and more close to people's daily life. People have already enjoyed the convenience brought by the cloud unconsciously, however, they also need to bear the inconvenience brought by the cloud while enjoying the convenience. Software testing technology based on fault model has developed rapidly in many years of research and practice. With the wide application of cloud computing, fault problems arise. More and more research has begun to focus on fault detection in cloud computing, and there are many fault detection methods to reduce failures in cloud computing. But there are still some problems: (1) the traditional software failure model can not completely cover all failures in cloud computing, so, in the process of fault detection, Some faults in cloud computing may not be detected. (2) some fault detection methods use fault features as indicators to detect faults, but the relationship between fault and fault features is unclear. In order to solve the above problems, this paper combines the fault model, fault characteristics and fault detection in cloud computing, first establishes the fault model in cloud computing, and then designs a detection method to detect the fault in cloud computing. Hope to improve the established fault model in the process of continuous testing. The main works are as follows: (1) in order to solve the problem of many kinds of faults and fast change in cloud computing, on the basis of studying software failures and fault models, the main contents of this paper are as follows: (1) in order to solve the problem of many kinds of faults and fast changes in cloud computing, According to the characteristics of cloud computing, the fault model in cloud computing environment is put forward, and the fault model of cloud computing is established by classifying the faults in cloud computing from four angles. (2) the relationship between fault and fault feature is defined, and the fault and fault feature in cloud computing environment are related. (3) aiming at the fault model and fault feature model of cloud computing, a fault detection scheme based on cloud computing is proposed. (4) A cloud fault detection system is designed and implemented, and the correctness of the scheme and the effectiveness of the system are verified by a large number of experiments.
