Manual Testing

This paper describes the testing process employed for testing the in-house developed cloud by using the Google open source tool PerfKit and employing techniques for increasing the performance. Though new tools for testing cloud are emerging into the market, there are aspects which are suited for manual testing and some which can be speeded up using automatic testing tools for various cloud environments for Infrastructure, Platform and Software services. This paper brings out the techniques best suited to test different features of Cloud computing environment and to figure out the lacuna in performance of cloud services. The authors also try to bring out solutions to improve the performance of cloud (recommend) by using various tools to figure out the debugging and analysis process guidelines to follow while fine tuning the performance of private clouds

Computing Paradigm

The idea of cloud computing aligns with new dimension emerging in service-oriented infrastructure where service provider does not own physical infrastructure but instead outsources to dedicated infrastructure providers. Cloud computing has now become a new computing paradigm as it can provide scalable IT infrastructure, QoS-assured services, and customizable computing environment. However, it still remains a challenging task to provide QoS assured services to serve customers with minimized cost, while also to guarantee the maximization of the business objectives (e.g. margin profit) to service provider and infrastructure provider within certain constraints. In order to address these issues, this chapter proposes a QoS-oriented service computing methodology, and discusses associated topics including service level agreement and associated reference architecture, green service, service metering and metrics, service monitoring, and on-demand resource provisioning. In the case study, we demonstrate how we employ QoS-oriented service computing in a multi-server, multi-user on-line game to facilitate the on-demand resource provisioning to maintain quality of service and quality of experience.

<p>Research problem: Cloud computing has become an important topic in many organisations, due to the benefits it can provide to businesses and their operations. This increased interest in cloud computing is also reflected in the records management profession. However, records managers using cloud computing need to be aware of many factors that could negatively affect control of their records, and be able to manage these potential implications. This study aims to discover the level of involvement that records managers have in decision-making relating to cloud computing, and also to determine how informed records managers are about the implications of cloud computing. Methodology: The research design used was a cross-sectional study, with an online web survey being distributed to members of the NZRecords mailing list (an e-mail list for the New Zealand recordkeeping community). Results: The results of this study highlight that records managers have low levels of involvement in cloud computing decision-making, and mostly do not believe that their opinions will influence decisions about cloud computing in their organisations. The findings of the survey reveal awareness of the potential implications of cloud computing is high, although more resources and training should be made available to these records managers, especially in the area of portability and interoperability of records in the cloud. Implications: Requests are made for additional training resources to be made available. Suggestions are made for further research into the factors affecting records managers’ involvement in cloud computing decisions.</p>
