In this paper, we propose an SLA-based approach to private cloud reliability. We examine how to formulate reliability SLAs, identify key customer scenarios and use accelerated testing to validate them. We propose the creation of a public cloud SaaS to enable the above reliability validation via a distributed, scalable model. We then illustrate an application of the above approach during the development...
Cloud based technology heavily changed the way how Enterprise Resource Planning (ERP) systems are handled through the whole lifecycle. The previous release-by-release driven by main version change (from pre-alpha to gold release) was developed into a continuous release management. Business processes although remained the same, but how can be determined, which part of the software needs to remain untouched,...
The idea that computation may be organized as a public utility, like water and electricity, was formulated in the 1960s by John McCarthy, a visionary computer scientist that championed mathematical logic in artificial intelligence. Cloud computing combines the best techniques and technologies of distributed system, parallel computing and grid computing. Is a utility computing that provides a scalable...
Software-as-a-Service (SaaS) has recently been adopted by many organizations to get their work done through subscription-based services. To leverage economies of scale, software and hardware resources are shared among multiple tenants who have different requirements that rapidly change with time. Responding to tenants' diverse needs requires SaaS providers to carefully manage software variability...
In a traditional process of software testing, an user have to buy servers and test tools to set up various test environment artificially, which causes high-cost, long test time and difficult test implements with limited resource. Cloud computing integrates a large number of physical resources into a pool and realizes the virtualization of various resources based on virtualization techniques. Users...
As the use of Internet, computers and mobile devices expands, a learning management system for college students has become necessary. Therefore, we design an efficient learning management system based on cloud computing for programming learning, which can advance student learning and interacting. We divide the learning management system into three platforms, i.e. SaaS learning platform, PaaS learning...
Leveraging Virtual Machine (VM) technologies to host multiple Web applications on the same physical machine can improve the resource utilization and thus save a cloud provider's provisioning cost. By allocating and scheduling virtual CPU (vCPU) resources for running VMs, a hosted Web application may achieve varying performances. Thus, when facing an end user with a specific SLA (Service Level Agreement)...
Recently, cloud computing has been recognized as effective computing model, being adopted by both large corporations as well as SMEs (Small and Medium Enterprises). Due to its on-demand provisioning nature number of cloud based services are growing gradually and rapidly. The availability of open-source cloud computing platforms plays a vital role to enable researchers to go beyond state of the art...
Cloud computing is a hot topic in the field of computer application, and it provides open services based on the carrier of the service model. Software service is one of the important services of cloud computing, and it is a great test to face changing business requirements for the cloud software service' ability of commonality. At present, the cloud software is difficult to ensure the flexibility...
This paper discusses the data security issues and concerns that are prevalent when organizations are moving their Enterprise Resource Planning (ERP) systems to the cloud. Cloud computing has reinvented how organizations conduct business and has enabled them to innovate and compete in a dynamic environment through new and innovative business models. The growing popularity and success of the cloud has...
Applications offered as Software-as-a-Service should pursue a multi-tenant architecture in order to be profitable. Multi-tenancy helps to reduce the number of application instances by sharing resources amongst several tenants, thus saving operational costs, particularly in public cloud environments. While research mostly discusses how to design green-field software in a multi-tenant manner, this paper...
Deception happens in social life. Social life is now omnipresent in cyber domains. As a result, deception is also evident in cyberspace. Deception in cyberspace is diverse and often differs from traditional social deceptions. Deception has a cost or a loss, often incurred by the victim of the deception. Hence it is important to detect deceptions, and to protect assets. In this work, we carry out analyses...
In contemporary IT and Internet society, Cloud computing brings a paradigm shift not only for successfully evolving large distributed software applications but also for delivering a number of innovative services and applications. Cloud computing is an umbrella enveloping several models of service, like SaaS, IaaS, PaaS, TaaS. In particular, software testing in/on/over cloud is the focus of this paper...
With the advent of cloud computing based technologies, the way to store and manage data has changed completely. With more data being generated every day, especially with other associated paradigms like Internet of Things (IoT), there will be a lot of data to be stored and managed in the cloud. Thus, it will be very important to know which cloud service is more suitable for what kind of data and data-management...
The paper proposes the method of building the electric power marketing business application system based on the cloud computing and microservices architecture technologies to solve the issues of the current system with the concentrated infrastructure and the monolithic architecture which are difficult to support the business processing in very large scale and the evolution of the electric power marketing...
With the appearance of distributed computing, associations are hoping to move their Customer Relationship Management (CRM) applications from an On-Premise environment or we can say local servers to an On-Demand environment that is on cloud server. On-Premise environment is when association has the framework and programming inside their system. In On-Demand environment, outsider has the base and programming...
At present, SaaS(Software as a Service) is a new mantra for many software industries and individuals. How software can be offered as a service? What are the requirements and issues of SaaS? What is architectural difference between SaaS, and other cloud computing models? What are the implementation challenges for SaaS? These are the few questions one need to answer while implementing SaaS. Offering...
In this paper, we conduct research on the construction and robustness testing of SaaS cloud computing data center based on the MVC design pattern. The SaaS software needs to experience the strict test before the issue. For all this, because is very difficult to forecast in the future all possible network users' to the service condition of SaaS system, therefore is also hard to conduct the completely...
In this paper, we design a cloud-based workflow platform, which can provide services for each campus application based on the same set of platform. It can reduce development costs, reduce the costs of purchasing software, hardware, storage and network, reduce the costs of data backup, system management and maintenance. It also can achieve the maximum degree of utilization of the platform. Each application...
The revolution in utility computing paradigm is brought by Cloud computing which replaces the traditional software installation. The cloud computing service models are basically classified into three parts i.e. software as a service (Saas), Platform as a service (Paas) and Infrastructure as a service (Iaas). There are four deployment models followed by Cloud computing i.e. Public Cloud, Private Cloud,...
