Framework of User Participation for the Interface Design in the SaaS Layer

The development of software as a service represents a great advantage for the users of cloud computing, such as users of small, medium or large organizations. All these users possess different characteristics, which must be taken into account as reference for the interface development of a software product. This paper considers the element of a user experience model, with the purpose of getting to know the different features that must be taken into account during the development of software as a service. This also involves the participation of different types of users of the SaaS layer model together with the users’ interaction skills level. This paper offers a framework of the involvement actors in the design of a software interface as a service, with the objective of identifying their participation outside and within the organization. The purpose is to create an interface centered on the user, involving clients and experts to work collaboratively; and get usable software as a service application.

The Moderating Effect of Subjective Norm on Cloud Computing Users’ Perceived Risk and Usage Intention

The high popularity and high demand of internet applications lead to faster development of cloud computing services that make network access become more convenient. However, using a new technology can cause users’ perceived risk because they worry about internet security and invasion of privacy. The study aims to explore the influence of end users’ perceived risk on usage intention of cloud computing services and the interactive effect of perceived risk and subjective norm on usage intention. The study dispatched 350 questionnaires to internet users. The amount of valid questionnaires is 238 and the effective response rate is 68%. The results showed that both perceived risk and subjective norm are significantly affected to usage intention, and subjective norm has a moderating effect on the relationship between perceived risk and usage intention.

Cloud Computing-Software as Service

Cloud Computing,” to put it simply, means “Internet Computing.” The Internet is commonly visualized as clouds; hence the term “cloud computing” for computation done through the Internet. With Cloud Computing users can access database resources via the Internet from anywhere, for as long as they need, without worrying about any maintenance or management of actual resources. Besides, databases in cloud are very dynamic and scalable. Cloud computing is unlike grid computing, utility computing, or autonomic computing. In fact, it is a very independent platform in terms of computing. The best Example of cloud computing is Google Apps where any application can be accessed using a browser and it can be deployed on thousands of computer through the Internet.

Visualizing and Assessing a Compositional Approach to Service-Oriented Business Process Design Using Unified Modelling Language (UML)

In the context of Service-Oriented Architecture (SOA), complex systems can be realized through the visualization of business driven processes. The automation of Service Supported Systems (SSS) is the future integral part of core SOA which provides preprocessed information and solution suggestions for the Cloud Computing Users (CCU). CCU requires compact and fast decision supporting displays and user interface in order to handle the increasing work load. This requires intelligent, intuitive and robust preprocessing system as a backbone for automation lifecycle management. Complex business management processes often entail complex environmental decision-making procedures. This process can be greatly enhanced if it is based on an exploratory-envisioning system such as Information Exploration and Visualization Environment. Current scientific research has taken advantage of e-science to enhance distributed simulation, analysis and visualization. Many of these infrastructures use one or more collaborative software paradigms like Grid Computing, High Level Architecture (HLA) and Service Oriented Architecture (SOA), which together provide an optimal environment for heterogeneous and distant, real-time collaboration. While significant progress has been made using these collaborative platforms, often there is no particular software suite that fulfils all requirements for an entire organization or case study. End-user must cope manually with a collection of tools and its exporting/importing capabilities to obtain the output needed for a particular purpose. We presents how service oriented architecture can be utilized in automation services support system using RCD framework as underlying composition platform. The introduced framework combines rapid analysis development and intelligent process state visualization for CCU and discusses the challenges met in building reliable cloud computing services for web services. Unified Modeling Language (UML) is used as a specification technique for the system analysis and design process which is the only way to visualize one’s design and check it against requirements before developers start to code.

CfunBASE: A Cosmological Functions Library for Astronomical Databases

ABSTRACTCfunBASE is a customizable C# cosmological functions library in the .NET framework. Its primary use is in CasJobs/SkyServer, where the functions are ported into a MS-SQL Server database hosting the SDSS science archive, and can be executed through simple T-SQL commands. This gives cloud-computing users the possibility of calculating cosmological distances, volumes and times as a function of redshift, as well as their respective inverse functions. Also included are basic data exploratory analysis tools, such as binning, N-dimensional weighted histograms, and quantile and cumulative distribution aggregate functions. Advanced astronomical examples are presented and discussed, such as the T-SQL implementation and fast computation of luminosity functions, color-magnitude diagrams, and the friends-of-friends galaxy cluster identification algorithm.
