Despite the big number of software process models currently available which have been used and practiced for many years, we could not till now totally solve the problem of projects’ late submissions! Meanwhile Software have constantly become bigger, more complex, and require high quality. A recently developed model, called DevOps, aims at producing fast and high-quality releases by bringing the development and operation team to work together. Unfortunately, DevOps is still lacking a clear definition as well as empirical studies that document the experience in implementing and enhancing it. Maturity models are used as a tool to assess the effectiveness of an organizational processes on adopting certain practices and identify what capabilities they need to acquire next in order to improve their performance and reach higher maturity level. However, there are few DevOps maturity models which have been emerged as means to assess DevOps adopted practices. This research aims to identify and benchmark the DevOps maturity models available in literature. We were able to identify several maturity models and compare among them
Wi-FI has become one of the dominant technology for direct access to the Internet due to its expanded services offering, its simplicity and its high-bandwidth provisioning that gives a capacity to support high traffic. Software-defined network (SDN) architecture simplified network management through an automatically programmed network. It provides a separation between the control plan (Controller) and the data plan (Switch) functions of the networks, this allows network optimization and fast response to network changes without the need to manually reconfigure existing infrastructure or purchase new hardware. In this paper, we have proceeded by studying the exchanges during a mobility within a WI-FI-based SDN network, then a network performance evaluation has been performed in order to analyze the impact of introducing the SDN concept on the performance of a mobile Wi-Fi network. For all proposed scenarios, we notice that the Wi-Fi-Based SDN architecture gives better results than in the case of the traditional Wi-Fi network.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
