Factors affecting net benefit of Google Drive adoption decision : a case study of Thais’ living in Bangkok, Thailand
Purpose: The research proceeded to investigate the factors affecting net benefit of google drive adoption decision among Thais living in Bangkok, Thailand. Design/Methodology/Approach: The data were collected from 412 respondents through convenient sampling technique by online questionnaire. Information quality, system quality, service quality, user satisfaction, intention to use and net benefit, validity and reliability of each variables were examined by Confirmatory Factor Analysis (CFA) and Structural Equation Model (SEM). Findings: The results showed that user satisfaction has the most direct effect on net benefit. Moreover, information quality, system quality and service quality were indirectly affected on net benefit of google drive. Therefore, google drive serve quality system that matches with customer satisfaction and expectation to improve job efficiency. Practical Implications: Although previous studies have identified on the use of google drive in collaborative business operations. However, the factors behind the use of google drive cloud system and the decisions behind the adaptation would provide useful insights for better understanding of the mechanism. Originality/Value: This research provides advanced recommendations to those who concern on the use of efficient google drive features not only to develop its features, but also to strengthen the smooth and flexible work patterns in organizations.peer-reviewe
SLA-Oriented Resource Provisioning for Cloud Computing: Challenges, Architecture, and Solutions
Cloud computing systems promise to offer subscription-oriented,
enterprise-quality computing services to users worldwide. With the increased
demand for delivering services to a large number of users, they need to offer
differentiated services to users and meet their quality expectations. Existing
resource management systems in data centers are yet to support Service Level
Agreement (SLA)-oriented resource allocation, and thus need to be enhanced to
realize cloud computing and utility computing. In addition, no work has been
done to collectively incorporate customer-driven service management,
computational risk management, and autonomic resource management into a
market-based resource management system to target the rapidly changing
enterprise requirements of Cloud computing. This paper presents vision,
challenges, and architectural elements of SLA-oriented resource management. The
proposed architecture supports integration of marketbased provisioning policies
and virtualisation technologies for flexible allocation of resources to
applications. The performance results obtained from our working prototype
system shows the feasibility and effectiveness of SLA-based resource
provisioning in Clouds.Comment: 10 pages, 7 figures, Conference Keynote Paper: 2011 IEEE

ERP implementation methodologies and frameworks: a literature review
Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

Cloud Migration: A Case Study of Migrating an Enterprise IT System to IaaS
This case study illustrates the potential benefits and risks associated with
the migration of an IT system in the oil & gas industry from an in-house data
center to Amazon EC2 from a broad variety of stakeholder perspectives across
the enterprise, thus transcending the typical, yet narrow, financial and
technical analysis offered by providers. Our results show that the system
infrastructure in the case study would have cost 37% less over 5 years on EC2,
and using cloud computing could have potentially eliminated 21% of the support
calls for this system. These findings seem significant enough to call for a
migration of the system to the cloud but our stakeholder impact analysis
revealed that there are significant risks associated with this. Whilst the
benefits of using the cloud are attractive, we argue that it is important that
enterprise decision-makers consider the overall organizational implications of
the changes brought about with cloud computing to avoid implementing local
optimizations at the cost of organization-wide performance.Comment: Submitted to IEEE CLOUD 201
