India. Abstract: In this paper we reviewed the technical and service aspects of different Cloud providers and presents the comparisons of these selected service offerings in cloud computing. By this User can have good understanding regarding services provided to avoid bottlenecks are also obstacles that could limit the growth. This comparison of cloud service providers, to serve as a starting point for user looking to take throw service and for Selecting the better one for there need into cloud environment . Keywords: Cloud Computing, Service Vendors, Cloud Services. I. Introduction As the use of computers in our day-to-day life has increased, the computing resources that we need also grown up. It was costly to buy a mainframe and computer‘s, it became important to find the alternative ways to get the greatest return on the investment, allowing multiple users to share among both the physical access to the computer from multiple terminals and to share the CPU time, eliminating periods of inactivity, which became known in the industry as time- sharing[1]. The origin of the term cloud computing is vague, but it appears to derive from the way of drawings of stylized clouds to denote networks in diagrams of computing and communications systems.Cloud computing is a paradigm shift in which computing is moved away from personal computers and even the individual enterprise application‘s to a ‗cloud‘ of computers.

  • Based Services Using XRI-Based Apis for Enabling New E-Business
    International Journal of E-Business Development May. 2013, Vol. 3 Iss. 2, PP. 64-74 An Approach for the Composition of Generic Cloud- Based Services Using XRI-Based APIs for Enabling New E-Business Antonio Celesti1, Francesco Tusa2, Massimo Villari3, Antonio Puliafito4 DICIEAMA, Università degli Studi di Messina Contrada Di Dio, S. Agata 98166, Messina, Italia [email protected]; [email protected]; [email protected]; [email protected] Abstract-Nowadays, cloud computing offers more and more business opportunities, and thanks to the concept of virtualization, different types of cost-effective Cloud-based services have been rising. Virtualization of computing, storage, and networking resources, and their interconnection is at the heart of cloud computing, hence enabling new E-Business scenarios. In such a context, APIs for enabling Cloud-based services are strongly required, nevertheless, methods, mechanisms and tools for exploiting virtualized resources and their utilization for developing anything as a service (*aaS) are still ad-hoc and/or proprietary in nature. In this paper, we discuss how to use an adaptive standard protocol, i.e., XRI, for enabling cloud service providers to arrange their own Cloud- based services, building them on top of the IaaS provided by other service providers. Keywords- Cloud Computing; Cloud Management; Federation; Service Composition; E-Business I. INTRODUCTION Today, cloud computing represents a tempting business opportunity for ICT operators of increasing their revenues [1,2]. The cloud ecosystem begins to be clearer and the role played by cloud service providers appears more defined than the past. Moreover, the number of new public, private, and hybrid clouds rising all over the world is continually growing [3].

  • Magic Quadrant for Enterprise High-Productivity Application Platform As a Service
    This research note is restricted to the personal use of [email protected]. Magic Quadrant for Enterprise High- Productivity Application Platform as a Service Published: 26 April 2018 ID: G00331975 Analyst(s): Paul Vincent, Van Baker, Yefim Natis, Kimihiko Iijima, Mark Driver, Rob Dunie, Jason Wong, Aashish Gupta High-productivity application platform as a service continues to increase its footprint across enterprise IT as businesses juggle the demand for applications, digital business requirements and skill set challenges. We examine these market forces and the leading enterprise vendors for such platforms. Market Definition/Description Platform as a service (PaaS) is application infrastructure functionality enriched with cloud characteristics and offered as a service. Application platform as a service (aPaaS) is a PaaS offering that supports application development, deployment and execution in the cloud. It encapsulates resources such as infrastructure. High- productivity aPaaS (hpaPaaS) provides rapid application development (RAD) features for development, deployment and execution — in the cloud. High-productivity application platform as a service (hpaPaaS) solutions provide services for declarative, model-driven application design and development, and simplified one-button deployments. They typically create metadata and interpret that metadata at runtime; many allow optional procedural programming extensions. The underlying infrastructure of these solutions is opaque to the user as they do not deal with servers or containers directly. The rapid application development (RAD) features are often referred to as "low-code" and "no-code" support. These hpaPaaS solutions contrast with those for "high-control" aPaaS, which need professional programming — "pro-code" support, through third-generation languages (3GLs) — and provide transparent access to the underlying infrastructure.

  • Automated System and Service Monitoring with Openqrm and Nagios
    Name: Matthias Rechenburg Email: [email protected] Organization: the openQRM project Copyright (C) 2007 Matthias Rechenburg This document is released under the GNU/GPL Automated system and service monitoring with openQRM and Nagios The first step to make sure all systems and services in a data centers are running well is to monitor them. A well-known, proven and widely used monitoring tool is Nagios which is available for openQRM in the flavor of an additional plugin. The second, also essential, step is the automatic handling of errors, what openQRM is famous for. The combination of the enhanced monitoring utility Nagios and the automated error-handling, high-availability and fail-over features of the openQRM data center management platform creates a powerful and dynamic environment which reduces down-time of systems and services in a modern data center to the minimum. Common data center scenarios and their challenges In a common data center setup there are different server “islands” for specific purposes as databases, web-servers, infrastructure and communication systems, network-devices, storage-servers, etc. Also, often there is a separation between production-, QA- and development environment. Each section of the data center has its own specific setup, mostly a very special, static installation, maintained by one or more administrators. To make it worse, each section may have different service-level-agreements (SLA) which generates additional complexity for the service- and system-monitoring infra- structure. Also common for data centers is that new systems are added sequentially while other systems are fully underutilized, just consuming power and producing heat. Turning to fully automated system- and service monitoring With the increasing number of systems and the resulting complexity the goal is to reach a level of fully automated service- and system-monitoring which is easy to setup and maintain and which provides an automated error-handling to gain high-availability at system- and service-level for the complete data center environment.

  • Paas Solutions Evaluation
    PaaS solutions evaluation August 2014 Author: Sofia Danko Supervisors: Giacomo Tenaglia Artur Wiecek CERN openlab Summer Student Report 2014 CERN openlab Summer Student Report 2014 Project Specification OpenShift Origin is an open source software developed mainly by Red Hat to provide a multi- language PaaS. It is meant to allow developers to build and deploy their applications in a uniform way, reducing the configuration and management effort required on the administration side. The aim of the project is to investigate how to deploy OpenShift Origin at CERN, and to which extent it could be integrated with CERN "Middleware on Demand" service. The student will be exposed to modern cloud computing concepts such as PaaS, and will work closely with the IT middleware experts in order to evaluate how to address service needs with a focus on deployment in production. Some of the tools that are going to be heavily used are Puppet and Openstack to integrate with the IT infrastructure. CERN openlab Summer Student Report 2014 Abstract The report is a brief summary of Platform as a Service (PaaS) solutions evaluation including investigation the current situation at CERN and Services on Demand provision, homemade solutions, external market analysis and some information about PaaS deployment process. This first part of the report is devoted to the current status of the process of deployment OpenShift Origin at existing infrastructure at CERN, as well as specification of the common issues and restrictions that were found during this process using different machines for test. Furthermore, the following open source software solutions have been proposed for the investigation of possible PaaS provision at CERN: OpenShift Online; Cloud Foundry; Deis; Paasmaster; Cloudify; Stackato; WSO2 Stratos.

  • A Private Cloud Architecture Designed for High Usability
    THUNDER: A PRIVATE CLOUD ARCHITECTURE DESIGNED FOR HIGH USABILITY by GABRIEL JACOB LOEWEN SUSAN VRBSKY, COMMITTEE CHAIR MONICA ANDERSON JOHN LUSTH ASHRAF SAAD JINGYUAN ZHANG A DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Department of Computer Science in the Graduate School of The University of Alabama TUSCALOOSA, ALABAMA 2015 Copyright Gabriel Jacob Loewen 2015 ALL RIGHTS RESERVED ABSTRACT Cloud computing is a technological strategy for saving time, money, and resources within an organization. Underfunded and understaffed organizations benefit the most from a cloud archi- tecture because it can help to alleviate a cost burden allowing funds to be used more effectively. Therefore, we believe that non-profit organizations, such as schools, libraries, non-profit medical facilities, and others have the most to gain from cloud computing. Cloud computing has played a major role in shaping large for-profit businesses like Google, Amazon, and Microsoft. Research has suggested that cultural barriers make it difficult for professionals in non-profits to adopt cloud computing technology. One key challenge faced by organizations for which a cloud architecture would be benefi- cial is the deployment and management process. In order for private cloud computing to become a viable solution for struggling organizations, much work needs to be done to simplify and im- prove the deployment process. We describe a new cloud architecture called THUNDER, which is a recursive backronym meaning “THUNDER Helps Underfunded Nonprofits Distribute Electronic Resources.” THUNDER introduces strategies which are meant to help struggling organizations to de- crease costs. Virtual machine load balancing attempts to distribute the load across multiple nodes in order to maximize potential performance of virtual machines.
