Migrating web applications to clouds with microservice architectures

Abstract: For the recent advances of Cloud Computing technologies, cloud applications have been popularity for their rich set of features. Therefore, their practical use for promoting business values can be expected. As such, cloud applications are recognized as a trend for the next generation of existing Web applications, and hence how to migrate these Web applications to the clouds becomes a desired field in the literature. For this need, we present a migration method that employs the well-known microservice architectures to support an effective migration of Web applications into the clouds.

Time efficient dynamic threshold-based load balancing technique for Cloud Computing

Abstract: Cloud computing is a novel technology leads several new challenges to all organizations worldwide. Cloud computing supports virtual machines (VMs) to host multiple applications simultaneously. Balancing the large numbers of applications in the heterogeneous cloud environment becomes challenging as the hypervisor scheduling controls all VMs. When the scheduler allocates tasks to the overloaded VMs, the performance of the cloud system degrades. In this paper, we present a novel load balancing approach to organizing the virtualized resources of the data center efficiently. In our approach, the load to a VM scales up and down according to the resource capacity of the VM. The proposed scheme minimizes the makespan of the system, maximizes resource utilization and reduces the overall energy consumption. We have evaluated our approach in CloudSim simulation environment, and our devised approach has reduced the waiting time compared to existing approaches and optimized the makespan of the cloud data center.

Developing virtual team performance: an integrated perspective of social exchange and social cognitive theories

Abstract: The emerging trend toward physically distributed work teams has necessitated a critical inquiry into the nature and roles of psychological contract and leadership in virtual settings. This study proposes a model based on social cognitive theory and social exchange theory to explain virtual team performance in the information technology industry. In the proposed model, virtual team performance is directly influenced by IT training fulfillment, transactional fulfillment, and knowledge-oriented leadership and also indirectly via the partial mediation of collective IT efficacy. This study adds to the burgeoning theoretical and empirical research on virtual teams by assessing the joint effects of psychological contract fulfillment and knowledge-oriented leadership. Empirical testing of this study at the team level, by surveying team members and leaders across two different points of time, confirms the integrated applicability of social exchange and social cognitive theories in understanding the development of virtual team performance.

Corporate social irresponsibility, CEO overconfidence, and stock price crash risk

Abstract: This study examines whether and how corporate social irresponsibility (CSI) influences stock price crash risk for firms with overconfident CEOs. We find that the positive association between CEO ov...

Expression of eggplant ascorbate peroxidase increases the tolerance of transgenic rice plants to flooding stress

Abstract: Rice is sensitive to flooding during seed germination and early seedling growth. The objective of this study was to transfer ascorbate peroxidase (APX) cDNA from the eggplant (Solanum melongena, Sm) under the control of an ubiquitin promoter into rice (Oryza sativa) via Agrobacterium-mediated transformation. A real-time polymerase chain reaction analysis demonstrated that SmAPX gene was over-expressed in transgenic rice lines (SmAPXs). APX gene expression profiles were well matched with the data for APX enzyme activities and total chlorophyll contents in the non-transgenic (NT) and transgenic plants. The activity of APX in the transgenic line SmAPX6 was 9-fold higher than in NT plants under waterlog, and the amount of APX in the SmAPX6 line also accumulated greatly according to a Western blot analysis. The over-expression of SmAPX in rice seedlings exhibited stronger resistance to flood tolerance, less oxidative injury, and grew faster than NT plants exposed to flood treatment.
