Multiple Metrics

The continuous and swift progress in the number of the cloud data centers have led to establishment of multitudes of the computational nodes and the huge paradigm. But the assuring the quality of services through these paradigms is still questionable. So tit has become a prominent areas of research. As the quality of service of the data centers plays a vital role in the user satisfaction. The present work carried out in the paper survey the service quality rendered in the previous similar work, identifies the drawbacks and proposes a strategy of migration taking into consideration the multiple metrics. The proposed structure is validated through the cloud simulator to evince its capability in efficiently handling the resources and guaranteeing the quality of service.

Load Balancing Algorithm

To scale back the energy consumption, this paper proposed three algorithms: The first one is identifying the load balancing factors and redistribute the load. The second one is finding out the most suitable server to assigning the task to the server, achieved by most efficient first fit algorithm (MEFFA), and the third algorithm is processing the task in the server in an efficient way by energy efficient virtual round robin (EEVRR) scheduling algorithm with FAT tree topology architecture. This EEVRR algorithm improves the quality of service via sending the task scheduling performance and cutting the delay in cloud data centers. It increases the energy efficiency by achieving the quality of service (QOS).

PurposeThe purpose of this study is to measure the gap and compare the quality of services provided by the Central Library of the University of Tehran and Allameh Tabataba'i University and identify the components of service that need improvement in these libraries.Design/methodology/approachIn this study, a descriptive survey method is used for data collection. The study sample contains 205 people selected out of 31,000 members of Tehran University and 100 people out of 15,000 members at Allameh Tabataba'i University. The LibQual tool is used to measure different levels of users' perceptions of library service quality.FindingsBased on the findings of the study, the level of service received at the University of Tehran was higher than the minimum expected level, and at Allameh Tabataba'i University, the level of service received was lower than the minimum level of expected, which indicates users' satisfaction at this index at the University of Tehran and users' dissatisfaction at Allameh Tabataba'i University. In the index of information control and library as a place in Tehran University, the level of service received was higher than the minimum level and in Allameh Tabataba'i University, the level of service received was lower than the minimum level, which indicates the satisfaction of users in this index at the University of Tehran and users' dissatisfaction at Allameh Tabataba'i University.Practical implicationsService quality, or quality of service, is the measurement and comparison of the size of service provided with users' expectations. The following principles illustrate the dimensions of service quality: Quality of service is much more difficult to measure than the quality of goods. The quality of service is based on users' expectations. Quality of service varies in status, meaning that the quality of a service is measured against the customer's initial expectations of that service (Parasuraman et al., 1985).Originality/valueBeing the first performance evaluation, community synchronization, economic justification, user satisfaction and customer orientation are the values of the present study.

Load Balancing Algorithm

Cloud computing is a vigorous technology by which a user can get software, application, operating system and hardware as a service without actually possessing it and paying only according to the usage. Cloud Computing is a hot topic of research for the researchers these days. With the rapid growth of Interne technology cloud computing have become main source of computing for small as well big IT companies. In the cloud computing milieu the cloud data centers and the users of the cloud-computing are globally situated, therefore it is a big challenge for cloud data centers to efficiently handle the requests which are coming from millions of users and service them in an efficient manner. Load balancing is a critical aspect that ensures that all the resources and entities are well balanced such that no resource or entity neither is under loaded nor overloaded. The load balancing algorithms can be static or dynamic.  Load balancing in this environment means equal distribution of workload across all the nodes. Load balancing provides a way of achieving the proper utilization of resources and better user satisfaction. Hence, use of an appropriate load balancing algorithm is necessary for selecting the virtual machines or servers. This paper focuses on the load balancing algorithm which distributes the incoming jobs among VMs optimally in cloud data centers. In this paper, we have reviewed several existing load balancing mechanisms and we have tried to address the problems associated with them.

To determine the level of success and effectiveness of MOOC in the learning system, it is important to measure the quality of service. The aim of this study is to measure the perceptions and expectations of MOOC users. The method of this study is the SERVQUAL model which is combined with a fuzzy approach, so that it can be measured accurately. From the calculation, the results show that Reliability dimension has the largest gap with a gap value (-13,2325), so there are needed an improvement by the university. While Assurance dimension has the smallest gap with a value of gap (-10,0025) this is considered by the user to be a better dimension than the others. From the calculation of the overall gap value obtained, the result shows a value of -57.65, which means that the quality of service received by users is not in line with expectations.

Customer satisfaction is the level of customer feeling towards the evaluation of perceived discrepancies between performance or perceived results compared to expectations. Quality is the level of excellence expected to meet customer desires which is a dynamic condition related to products, services, people, processes and the environment that meets or exceeds expectations. Factor analysis is a multivariate analysis method based on correlations between variables. This study discusses the factors of customer satisfaction with service quality in the Mengwi Badung Station. The factors of user satisfaction with the quality of service at the Mengwi Badung Station are caring, physical condition, guarantee, reliability, and responsibility factors.
