A QoS-driven approach for cloud computing addressing attributes of performance and security

With ever increasing usage of IT infrastructure around the globe, the increase in energy consumption and carbon emission is a worrisome situation for everyone because of its direct effect on environment. The environment is being dangerously impacted by Information Technology infrastructure extensive use and its waste. Cloud computing has emerged as one step further solution to deploy all virtualized IT resources as per need on self-service basis as a rental method for the users. Different cloud deployment methods have emerged according to the need of users, institutions and communities. In last decade virtualization has been a milestone in enabling optimal usage of information technology resources. Cloud computing has provided a platform for deploying everything as a Service in IT, which has changed the economics of IT based business and organizations from Capital Expenditure to Operational Expenditure. For enabling Cloud services we first need to understand our existing infrastructure. In second step we should be able to virtualize it for optimal usage. Then with the help of existing cloud applications we can deliver and deploy information technology as a resource at various levels such as infrastructure, platform, and software. Keywords; cloud computing, carbon emission, energy consumption, IT waste, virtualization. The Advancement in the field of information technology has enabled us to optimize the use of physical infrastructure with the help of virtualization, most of which is only used in specific applications like vitalizing a local area network on switch or vitalizing a compute resource to run more than one operating system on a desktop. The benefits of same has not been completely implemented and utilized in industrial environments where we require a large amount of IT resources. The advantage of using cloud is to enable complete utilization of Information technology resources, where most of the resources are underutilized. The cost involved in maintenance and management of those resources is huge which can be saved due to centralized management of private cloud infrastructure. We create private cloud keeping in mind. • Availability and performance requirements for the cloud • Infrastructure sizing, performance and continual availability requirements • The need for data security or isolation • The appropriate user interface With advent of IT as a service in cloud computing technology energy consumption and related carbon emissions and waste are considerably lesser than in-house implementation. Technology in Cloud Computing creates an able structure for sharing resources with the help of virtualization among many; it greatly decreases or abolishes the need for most products, equipment, utilities and facilities. The results are more sustainable IT infrastructures and processes which help in keeping environment safe. • Highest resource consumption and effectiveness • Reduced energy consumption by up to 95 % with the help of virtualization which optimizes the use of physical infrastructure and thereby helps IT to be delivered as a service. • Displaced utility costs Workstation utility costs are cut by 90% due to change of capital expenditure into operational expenditure in industries or organizations across the world. • Reduced electronic waste as No more batteries and minimal software/hardware waste. • Reduced waste overall due to consumption of computational power as service, no more as infrastructure. • Reduced ecological impact of workstations as compared to thin clients as anything related to computation can be provided as a service on a client connected with internet to the cloud provider.

Despite growing demand, the information technology (IT) field suffers from a labor shortage compounded by the underrepresentation of women in the IT field. This study examined predictors of occupational and organizational commitment outcomes among IT professionals and explored gender differences and similarities in the relative importance of predictors. 1,229 IT professionals provided web-based survey data, which were analyzed using hierarchical linear modeling and relative weight analysis. Satisfaction with growth opportunities, job security, job stress, and work–family culture generally were related to commitment outcomes as expected, accounting for the greatest variance in organizational commitment. Relative weights for men and women differed in the prediction of occupational commitment, where growth satisfaction and work–family culture were weighted more strongly by women and job stress was more strongly weighted by men. For organizational commitment, the relative weights among predictors were similar for men and women, except that men weighted job security more strongly than women. Findings suggest that garnering commitment to the IT field requires a gender-specific approach, highlighting growth and work–family support for women and addressing job stress for men. Increasing organizational commitment for both men and women calls for an emphasis on opportunities for growth and development. This is the first study to simultaneously examine predictors for organizational and occupational commitment among IT professionals and to assess the relative importance of predictors discussed in the extant literature. Results inform efforts to increase retention in the IT field and provide guidance for improving the representation of women in IT.

본 연구는 공공부문에서 수행한 정보통신분야 인력양성사업을 평가하기 위하여 산업연관분석방법론에 최근 내생적 성장이론의 이론적 배경을 결합하여 정보통신산업관련 인적자본을 9개 산업으로 분류한 뒤에 정보통신분야 인적자본의 후방승수와 전방승수라는 두 가지 관점에서 분석하였다. 본 연구의 결과는 첫째, 예산의 투입에 따라 인적자본형성이 매년 증가함에 따라, 정보통신분야 인력양성사업은 경제적 외부성이 존재하고 있음을 뒷받침하고 있다. 둘째, 정부의 IT인력양성사업 중에서 전략적인 부분으로 후방연관효과가 큰 분야는 연구(R&D)분야로 나타나 인력양성(HRD)은 연구분야(R&D)와 연계해야 효과가 높은 것을 반증해 주고 있다. 또한 다른 산업에 유발효과가 높은 분야는 정보통신 서비스 부분(IT응용기술 교육)으로 나타났다. 셋째, 인력양성사업으로 인한 부정적인 효과인 가격상승효과도 존재하는데, 사업규모도 적고 일회성 사업 등에 대한 정책적 고려가 필요하다. 마지막으로, 인력양성사업이 유발하는 경제적 파급효과를 자체 부분의 직접효과와 다른 부분에 미친 간접효과를 합하여 계산할 경우, 전체적으로 정보통신분야 인력양성사업의 경제성은 매우 좋은 것으로 나타났다. 【This study investigates both backward and forward multipliers of human capital in the field of information technology in order to evaluate human resources programs which were executed in the public sectors. Dynamic interindustry linkages analysis was employed as a methodology after classifying human capitals related to information technology into 9 industries. First, empirical findings showed that there are economic externalities in the IT HRD programs when the formation of human capital increases with more investment in them. Second, another finding was that the effect of HRD programs could be powerful when HRD programs were closely connected with R&D programs, showing that R&D programs among IT HRD programs have huge backward linkage effect. In addition, IT service sector has its own spill-over effect to other industries. Third, however, small budget and one off HRD programs should be considered as a negative price synergy effect. Finally, overall economic feasibility of IT HRD programs turned out to be excellent with consideration of their own economic direct and indirect effect.】

Insider threats remain a critical concern in cloud environments, necessitating robust strategies for detection and mitigation. This paper proposes a holistic approach that integrates Behavioral Anomaly Detection (BAD) with existing security measures to mitigate insider threats effectively. BAD focuses on identifying abnormal behaviors that deviate from established patterns, making it a valuable tool for detecting insider threats. The holistic approach combines BAD with other security mechanisms such as access control, encryption, and user monitoring to create a comprehensive defense strategy. The key advantage of this approach is its ability to adapt to the dynamic nature of insider threats. By continuously analyzing user behavior and identifying anomalies, the system can detect potential threats early, allowing for timely intervention. Moreover, the holistic approach reduces the number of false positives compared to using BAD in isolation, thereby improving the efficiency of threat detection. To demonstrate the effectiveness of the approach, we provide a detailed implementation plan and showcase case studies from real-world cloud environments. Our evaluation results indicate that the holistic approach significantly enhances the security posture of cloud environments against insider threats. By leveraging BAD and integrating it into a holistic security framework, organizations can better protect their sensitive data and infrastructure from insider threats. This research contributes to the field of cloud security by providing a practical and effective strategy for mitigating insider threats. It also opens up avenues for future research, such as exploring the integration of machine learning techniques to enhance BAD's detection capabilities further.

The article analyzes conceptual foundations, views and ideas on understanding the essence and forms of using special knowledge while detecting and investigating crimes in the field of computer-based information and high technologies, and addresses its concepts. The relationship between similar concepts of forensic expert and third party expert has been traced, since one of the main problems considered in the framework of forensic examination is ambiguity of both scientific understanding and practical application of the corresponding conceptual-categorical apparatus. In our opinion, special knowledge in detecting and investigating crimes in the field of computer-based information and high technologies implies knowledge in various fields of science, including law, technology, arts and crafts, in relation to the field of computer-based information and high technologies, obtained within the framework of professional or special education, professional activity, as well as knowledge of theory, skills and abilities, and used by participants in civil, arbitration, administrative and criminal proceedings in order to establish circumstances to be proven in a particular case, in the manner provided by relevant procedural legislation of Ukraine.

The article analyses the definitions of ‘pedagogical conditions’ and ‘foreign language communicative competence’. It is noted that European integration processes, the spread of multicultural education and Ukraine's active participation in international educational programs have led to an increase in the requirements for the level of foreign language proficiency among students for higher and professional higher education. The relevance of the study is due to globalisation processes that put forward new requirements for the training of specialists and foreign language proficiency is becoming an integral part of professional activities in the field of information technology. The scientific novelty of the study is to substantiate the pedagogical conditions for the development of foreign language communicative competence, taking into account the specifics of training specialists in the field of information technology. It has been determined that the successful formation of foreign language communicative competence in information technology students depends on a set of pedagogical conditions. The first pedagogical condition is the formation of motivation for future IT specialists to learn foreign languages; the second pedagogical condition is the systematic use of digital interactive technologies as a means of forming foreign-language pedagogical competencies; the third pedagogical condition is the creation of professionally directed educational and methodological support (workbooks in English for professional purposes for each semester) for foreign language training of future IT specialists in institutions of professional higher education; the fourth pedagogical condition is the readiness of foreign language teachers to use professionally directed educational and methodological support. As a result of the study, recommendations have been developed for the implementation of effective foreign language teaching strategies that will help improve the level of foreign language communicative competence of future specialists in Industry 12 – Information Technology. The recommendations cover such aspects as the selection of teaching materials, the use of interactive teaching methods, the development of workbooks, the use of digital technologies, the organisation of the educational process and the assessment of learning outcomes.
