Modeling and Analysis of State-of-the-art VM-based Cloud Management Platforms

Abstract

Abstract-Virtualization is one of the key aspects used in cloud computing environment to achieve scalability and flexibility. To cope with the large number of virtual machines (VM) involved in the cloud, several solutions have been proposed to automatically monitor and deploy VM in resource pools. Most of the cloud management system, such as Amazon EC2, are proprietary and are not generally available for research. In the said perspective, many open source VM-based cloud platforms launched for general users to research. The existing work performed in VM-based cloud management platforms have mainly focused on the discussion of architecture, feature set, and performance analysis. However, other important aspects, such as formal analysis, modeling, and verification are usually ignored. In this paper, we provide a formal analysis, modeling, and verification of three open source state-of-the-art VM-based cloud management platforms: 1) Eucalyptus, 2) Open Nebula, and 3) Nimbus. We have used high-level Petri nets (HLPN) to model and analyze the structural and behavioral properties of the systems. Moreover, to verify the models, we have used Satisfiability Modulo Theories Library (SMT-Lib) and Z3 Solver. We modeled about 100 VM to verify the correctness and feasibility of our models. The results reveal that the models are functioning correctly. Moreover, the increase in the number of VM does not affect the working of the models that indicates the practicability of the models in a highly scalable and flexible environment.

Sensitivity Analysis Techniques Applied in Video Streaming Service on Eucalyptus Cloud Environments

“…With UEC architecture, it was addressed the availability of each component of the cloud base on Markov chain through the level analysis of hierarchical available model (HAM). Malik et al (2013) provided a formal analysis modeling and verification of open source state-of-art VM-based cloud management plataforms to model and analyze the structural and behavioral properties of the systems have used high-Level Petri Nets. In (Araujo et al, 2014), an availability model of a digital cloud library through a OpenNebula cloud manager is proposed, using an hierarchical approach to model and evaluate the digital library environment.…”

MATF: a multi-attribute trust framework for MANETs

“…Formally modeling systems helps to analyze the interconnection of components and processes and how the information is processed in the system [34]. Formal modeling provides valuable tools to design, evaluate, and [35].…”

“…SMT is an area of automated deduction for checking the satisfiability of formulas over some theories of interest and has the roots from Boolean satisfiability solvers (SAT) [34]. The SMT-Lib is an international initiative that provides a standard benchmarking platform that works on common input/output framework.…”

MDA: message digest-based authentication for mobile cloud computing

“…Therefore, we focus on the security aspect of mobile cloud computing, although many existing studies have attempted to address the behaviour, quality of service, scalability, flexibility, and pricing problem of cloud computing systems [27,29,35]. Addressing the security/vulnerability problem in mobile cloud computing is critical to the success of this promising technology.…”
