A Survey on Opensource Private Cloud Platforms

2014 16th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing, 2014

Cloud computing is continuously growing as a prominent technology for enterprises. While several giant public cloud providers, such as Amazon, Microsoft, IBM, Google are competing to extend their market, there is still a large number of organizations asking higher level of privacy and control over cloud solutions. Therefore, the need to have private cloud solutions is obvious. To overcome this need there are several ongoing open source software frameworks for building public and private clouds. Among them, OpenStack and CloudStack are growing at fast pace and gaining more attention. An analysis on these software stacks is necessary in order to choose the most suitable solution that matches an enterprise's requirements. This paper main contribution is an in depth study and comparison of the cloud properties of these two open source frameworks, providing useful information on open source cloud solutions that are not available elsewhere.

Scalable Computing: Practice and Experience, 2015

Cloud Computing is not only a pool of resources and services offered through the internet, but also a technology solution that allows optimization of resources use, costs minimization and energy consumption reduction. Enterprises moving towards cloud technologies have to choose between public cloud services, such as: Amazon Web Services, Microsoft Cloud and Google Cloud services, or private self built clouds. While the firsts are offered with affordable fees, the others provide more privacy and control. In this context, many open source softwares approach the buiding of private, public or hybrid clouds depending on the users need and on the available capabilities. To choose among the different open source solutions, an analysis is necessary in order to select the most suitable according with the enterprise's goals and requirements. In this paper, we present a depth study and comparison of five open source frameworks that are gaining more attention recently and growing fast: CloudStack, OpenStack, Eucalyptus, OpenNebula and Nimbus. We present their architectures and discuss different properties, features, useful information and our own insights on these frameworks.

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.

OpenStack is a massively scalable open source cloud operating system that is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. OpenStack provides series of interrelated projects delivering various components for a cloud infrastructure solution as well as controls large pools of storage, compute and networking resources throughout a datacenter that all managed through a dashboard(Horizon) that gives administrators control while empowering their users to provision resources through a web interface. In this paper, we present a comparative study of Cloud Computing Platform such as Eucalyptus, Openstack, CloudStack and Opennebula which is open source software, cloud computing layered model, components of OpenStack, architecture of OpenStack. Further discussing about how to install Openstack as well as how to build virtual machine (VM) in Openstack cloud using CLI on RHEL 6.4 and at last covering latest OpenStack releases Icehouse, which is used for building public, private, and hybrid clouds and introduce what new features added in Icehouse. The aim of this paper is to show mainly importance of OpenStack as a Cloud provider and give the best solution for service providers as well as enterprises.

Abstract- Cloud computing is a major change, caused by the underlying commoditization of IT. It is expected to see a future dominance of the open source model in cloud computing, which will solve the major adoption concerns for users. Even a small private cloud built on our college intranet gives us an idea of the dominance of cloud computing in near future. The scope of the cloud built in is scalable, allocate more capacity only when you need it, allocate more instances only when you need them, dynamic Instance Creation and Termination upon receiving a request. Cloud computing Services-A comparison Recognized as one of the Top 10 technologies of 2010 by Gartner, Cloud computing has generated a lot of interest and competition in the industry. With the emergence of new cloud Providers, identifying one that best suits the business needs of an enterprise is a challenging and difficult task. Adopting a cloud Provider requires a detailed study of parameters like data security, SLA's...

Cloud computing tends to be the next generation in ICT hosting platform. Customers can choose between many commercial and open source cloud platforms that exist on the market today. We installed and observed all of the possible features/configurations of one of the most common open source cloud platforms on the market today, i.e. the OpenStack, Eucalyptus, and OpenNebula. In this paper we present a methodology and evaluation of their capabilities.

Cloud computing refers to the concept of dynamic processing and optimization of storage allocation of computational resources in the "cloud". This system allows users to obtain and release the resources on demand and gain access to data by providing the relegation of the physical location and accurate parameters of the resources. Cloud computing systems are either proprietary or dependent on infrastructure software, which is the focus of this research. Open source (OS), which is a cloud infrastructure software, is popular in particular fields, such as operating systems, programming languages and software application, and, most importantly, cloud computing. However, public administrations, commercial enterprises, and other institutions have yet to incorporate Open source software in the cloud infrastructure of their organizations because of the lack of information and comprehension of such technology. This paper, therefore, will examine the principles of cloud computing, compare proprietary cloud computing and open source cloud computing, examine the OSCC platforms, and examine the open stack platform usage. Keywords: OS (Open source), OSS (Open source software), PaaS (platform as a service), IaaS (infrastructure as a service), SaaS (software as a service), OSCC (Open Source Cloud Computing).

In today's era educational organization strongly needs devices which are ready to access and use and also various operating system platforms are required for different learning courses. To achieve this type of environment hardware availability come in front as an important issue along with lots of money required to purchase them. Many educational courses required to run particular software or application on particular operating system platform along with specific hardware configuration. The maintenance of this different versions of operating systems and their installation stuff is hectic process and also required man power. To overcome all this problem there is solution called Cloud OpenStack. Cloud OpenStack allows us to develop an environment on commodity hardware or on existing system present in the educational organization. It's easily handle different version of OS platforms and also monitor and maintain them. Another important thing is many educational organizations still used Virtual machine method to used different OS platforms for various learning courses. This paper come up with implementation of Cloud OpenStack in Educational Organization and analyzing the results. The outcomes of Cloud OpenStack compare with the Virtual Machines method and find out which technique is better and more suitable for academics.

Cloud computing is a new technology widely studied in recent years. Now there are many cloud platforms both in industry and in academic circle. How to understand and use these platforms is a big issue. A detailed comparison has been presented in this paper focused on the aspects such as the architecture, characteristics, application and so on. To know the differences between open source and close source in cloud environment we mention some examples for Software-as-a-Service, Platform-as-a-Service, and Infrastructure-as-a-Service. We made comparison between them. Before conclusion we demonstrate some convergences and differences between open and closed platform, but we realized open source should be the best option.
