Despite the evolution of cloud computing in recent years, the performance and comprehensive understanding of the available private cloud tools are still under research. This paper contributes to an analysis of the Infrastructure as a Service (IaaS) domain by mapping new insights and discussing the challenges for improving cloud services. The goal is to make a comparative analysis of OpenNebula, OpenStack and CloudStack tools, evaluating their differences on support for flexibility and resiliency. Also, we aim at evaluating these three cloud tools when they are deployed using a mutual hypervisor (KVM) for discovering new empirical insights. Our research results demonstrated that OpenStack is the most resilient and CloudStack is the most flexible for deploying an IaaS private cloud. Moreover, the performance experiments indicated some contrasts among the private IaaS cloud instances when running intensive workloads and scientific applications.

Cloud Computing is becoming a viable computing solution for services oriented computing. Several open-source cloud solutions are available to these supports. Open-source software stacks offer a huge amount of customizability  without huge licensing fees. As a result, open source software are widely used for designing cloud, and private clouds are being built increasingly in the open source way. Numerous contributions have been made by the open-source community related to private-IaaS-cloud. OpenNebula - a cloud platform is one of the popular private cloud management software. However, little has been done to systematically investigate the performance evaluation of this open-source cloud solution in the existing literature. The performance evaluation aids new and existing research, industry and international projects when selecting OpenNebula software to their work. The objective of this paper is to evaluate the load-balancing performance of the OpenNebula cloud management software. For the performance evaluation, the OpenNebula cloud management software is installed and configured as a prototype implementation and tested on the DIU Cloud Lab. In this paper, two set of experiments are conducted to identify the load balancing performance of the OpenNebula
cloud management platform- (1) Delete and Add Virtual
Machine (VM) from OpenNebula cloud platform; (2) Mapping
Physical Hosts to Virtual Machines (VMs) in the OpenNebula
cloud platform.

كان يستخدم مصطلح السحابة في البداية للإشارة إلى الإنترنت، وذلك في مخططات الشبكات، حيث عرف على أنه رسم أولي لسحابة يتم استخدامها لتمثيل نقل البيانات من مراكز البيانات إلى موقعها النهائي في الجانب الآخر من السحابة. وقد جاءت فكرة البرامج كخدمات عندما عبر "جون مكارثي" الأستاذ بجامعة ستانفورد عن الفكرة بقوله "قد تنظم الحوسبة لكي تصبح خدمة عامة في يوم من الأيام"، حيث رأى أنه من الممكن أن تؤدي تكنولوجيا مشاركة الوقت إلى مستقبل تباع فيه الطاقة الحوسبية وحتى التطبيقات الخاصة كخدمة من خلال نموذج تجاري، وبالفعل حظت تلك الفكرة بشعبية كبيرة في أواخر الستينيات ولكنها تلاشت في منتصف السبعينيات عندما اتضح جلياً أن التكنولوجيا الحديثة المتعلقة بمجال تكنولوجيا المعلومات غير قادرة على الحفاظ على هذا النموذج من الحوسبة المستقبلية. ولكن عادت هذه الفكرة مؤخرا لتصبح مصطلحاً شائعاً في الدوائر التكنولوجية والمؤسسات في وقتنا الحالي.
وظهرت الحوسبة السحابية مرة أخرى كأحد أساليب الحوسبة، التي يتم فيها تقديم المصادر الحاسوبية كخدمات، ويتاح للمستفيدين إمكانية الوصول إليها عبر شبكة الإنترنت (السحابة)، دون الحاجة إلى امتلاك المعرفة، أو الخبرة، أو حتى التحكم بالبنى التحتية التي تدعم هذه الخدمات. كما يمكن النظر إلى الحوسبة السحابية على أنها مفهوم عام يشمل البرمجيات كخدمة، وغيرها من التوجهات الحديثة في عالم التقنية التي تشترك في فكرة الاعتماد على شبكة الإنترنت لتلبية الاحتياجات الحوسبية للمستفيدين.
ولكي يتعرف الباحثون والعلماء على البنية التحتية للحوسبة السحابية والخدمات التي توفرها - لابد من التعرف على النظم مفتوحة المصدر للحوسبة السحابية، ومن ثم تحاول هذه الدراسة إلقاء الضوء على ماهية الحوسبة السحابية وتاريخها وتطورها، وتعريف المصادر المفتوحة وتاريخها وتطورها، والعلاقة بين الحوسبة السحابية والمصدر المفتوح، ثم تحليل أحدث المعلومات حول أربعة من نظم الحوسبة السحابية مفتوحة المصدر، وهي: أوكالبتوس=  Eucalyptus، أوبين نيبولا= OpenNebula، ونيمبوس= Nimbus، وأوبن ستاك= Open Stack والمقارنة بينهم من ناحية التعريف والإمكانات المتاحة والخدمات والتقنية المتعلقة بكل نظام.

Abstract
It uses the term cloud initially to point to the Internet, networks, where custom schemes that a prototype of a cloud is used to represent the transfer of data from data centers to the final location on the other side of the cloud. The idea of programs as services came when "John mccarthy, Stanford University Professor" express on the idea by saying " computing may be managed to become a public service sometimes", where that technology of sharing time may lead to future of selling computational energy and even applications as a service through a business model, So this idea actually have great popularity in the late 1960s, but faded away in the mid-1970s when it became apparent that the modern technology on information technology is capable of maintaining This form of future computing. But this idea recently returned to become a term common in technological departments and institutions in the present.
Cloud computing has emerged recently again as one of the methods of computing, where providing computer resources as services, and allow users to access them via the Internet (cloud), without the need to acquire knowledge, or expertise, or even control of infrastructure that supports these services. Cloud Computing can also be seen as a general concept including software as a service, and other modern technical trends in the world involved in the idea of relying on the Internet for the computational needs of users.
In order to recognize researchers and scientists on the Cloud computing infrastructure and services provided by them -we must learn open source Cloud computing systems, so this study concentrate on the definitions of cloud computing, its history and development, and the definition of open source, history and development, and the relationship between cloud computing and open source, then analysis of the latest information about four open source cloud computing systems: Eucalyptus, opennebula, Nimbus, and Open Stack and compared them in terms of their definitions, possibilities and services and all related technology.
Keywords: Cloud Computing , Open Source , Infrastructure As A Service= (IAAS) , Eucalyptus , Opennebula , Nimbus , Open Stack.

IaaS (Infrastructure as a Service) clouds provide on-demand computing resources (i.e, memory, networking, storage and processing unit) for running applications. Studies that evaluate the IaaS cloud performance are limited to the virtualization layer and ignore the impact of management tools analysis. In contrast, our research investigates the impact of them in order to identify if there are influences or differences between OpenStack and OpenNebula. We used intensive workloads (microbenchmarks) and scientific parallel applications. Statistically, the results demonstrated that OpenNebula was 11.07% better using microbenchmarks and 8.41% with scientific parallel applications.

O objetivo do Projeto HiPerfCloud (High Performance in Cloud) é essencialmente a avaliação de desempenho das ferramentas de administração de IaaS (Infrastructure as a Service) e analisar o impacto que as mesmas podem causar em diferentes cenários (isolamento de recursos e, aplicações corporativas e de alto desempenho/paralelas). Visto que, as ferramentas possuem uma série de características particulares, surgiu a hipótese de que podem ter diferentes desempenhos e também impactar sobre as aplicações. Este documento relata os experimentos e resultados iniciais em direção à avaliação de desempenho nas ferramentas OpenStack e OpenNebula.

A computação em nuvem está se tornando cada vez mais presente nas infraestruturas empresarias e diversas ferramentas estão sendo criadas para auxiliar na administração dos recursos computacionais, que lidam diretamente com tecnologias de virtualização. No entanto, com tantas opções para a tomada de decisão, a escolha se torna difícil, devido a falta de informação disponível sobre o desempenho delas. Sendo assim, o objetivo deste trabalho é estudar, implantar e comparar os ambientes das ferramentas de administração de computação em nuvem (OpenStack e OpenNebula), analisando o desempenho de aplicações paralelas e da infraestrutura (usando benchmarks). Além disso, o trabalho buscou identificar se existem diferenças significativas no desempenho na implantação das ferramentas em relação ao ambiente nativo, e também entre elas. Para isto, foram executados testes de avaliação do desempenho da infraestrutura (Memória, disco, rede, e processador) e das aplicações de alto desempenho de cada a...

Nuvens computacionais consomem grandes quantidades de energia elétrica, sendo responsáveis pela emissão de pelo menos 2% do dióxido de carbono mundial. Por outro lado, as ferramentas de gerenciamento de nuvens atuais não dispõem de recursos para monitorar o consumo energético de suas infraestruturas, bem como não oferecem informações sobre a demanda de energia elétrica, sendo este uma parte integrante do custo de manutenção da nuvem. Portanto, este artigo propõe um modelo de monitoramento energético para nuvens computacionais. Foi criado um addon denominado Monitor Energético (ME) para monitorar o consumo energético em data centers virtualizados, através de Kernel-based Virtual Machine e geridos por OpenNebula. Os experimentos foram realizados com a ferramenta Sysbench para o estresse proposital do ambiente de testes, aonde os resultados comprovaram o bom funcionamento da nossa ferramenta e que ela possui uma visualização intuitiva do monitoramento.
