The rapid adoption and growth of cloud computing is creating unprecedented change in the manner in which IT services are procured, managed, and deployed. Cloud computing is forcing firms to rethink traditional IT governance practices while raising new and fundamental questions for scholars and practitioners. This paper identifies the major areas of change and highlights governance issues that arise with the adoption of cloud computing. The focus of this paper is on the organizational impact on IT governance under cloud computing. The paper posits (1) that successful IT departments under cloud computing will transform into new roles that address internal customer‐facing issues and external cloud‐facing issues, (2) firms that mitigate information asymmetry under cloud computing will show higher firm performance, and (3) firms that offer superior cloud‐sourced IT service attributes of internal prices, quality, variety, and competition in the cloud will show higher firm performance. 相似文献

This study aims to contribute to the literature on IT outsourcing governance by advancing our understanding of mechanisms of substitution and complementarity between formal and relational governance. Our study illustrates certain conditions under which substitution and complementarity can occur and depicts a two‐way causal relationship between them. Our examination further provides a more in‐depth assessment of relational governance by using the concept of the psychological contract. Our results demonstrate that the psychologically binding nature of the psychological contract makes it a particularly forceful substitute to formal governance, while its associations with other relationship aspects make it a forceful complement. 相似文献

The more large‐scale data centers infrastructure costs increase, the more simulation‐based evaluations are needed to understand better the trade‐off between energy and performance and support the development of new energy‐aware resource allocation policies. Specifically, in the cloud computing field, various simulators are able to predict and measure the behavior of applications on different architectures using different resource allocation policies. Yet, only a few of them have the ability to simulate energy‐saving strategies, and none of them support the complete advanced configuration and power interface (ACPI) specification. ACPI defines a terminology for all possible power states of a machine and their associated power rate. The hardware industry has relied on ACPI to provide up‐to‐date standard interfaces for hardware discovery, configuration, power management, and monitoring, enabling a better understanding of the energy consumption level of different hardware states, referred to as ACPI G‐states, S‐states, and P‐states. In this paper, we improve the modeling and simulation of the ACPI G/S‐states and show not only that these states offer different energy‐saving levels but also that state transitions consume energy. In addition, we model the latency to transit between two states and the effects on the turnaround time when the transitions are not performed conservatively. Furthermore, the equations provide essential information to quantify the trade‐off between energy consumption and performance and assist in the analysis/decision on which strategy fits better in the environment and how it could be refined. Our expanded energy model was implemented in CloudSim and validated with simulation‐based experiments with a very high level of accuracy, with a standard deviation of at most 6%.
