The use of virtualization can be attributed to the success of cloud computing. However, usage of a hypervisor in a shared environment among mistrusting users presents significant challenges. This paper surveys the works on host hypervisor security issues presented in cloud computing, performing a short review of current literature on the subject. Addressing several key topics, namely threats and known attacks against the hypervisor or a virtual machine (vm) that exist in a shared environment. This paper also contains a thorough review and comparison of the current solutions and proposed mitigations for the known attacks and identifies any potential gaps. Aiming to uncover if a hypervisor can provide the level of confidentiality, integrity and availability expected by cloud consumers. Research is critically analyzed and consideration for each solutions suitability of implementation in an Infrastructure as a Service (IaaS) environment is applied, including the impact on performance, if any.

Studying the historical facts of past wars and armed conflicts and natural and man-made emergencies, today in the Republic of Kazakhstan one of the most important security issues is the preparation and organization of the evacuation of the population from possible dangerous zones, taking into account the emergence of new threats to the country’s security. The paper presents an algorithm for constructing universal scales of the distribution function of opportunities by types of support and rebuilding them into subject scales using display functions. The purpose of the paper is to determine the integral indicators characterizing the possibility of accommodation of the evacuated population and the impact on resources during relocation. On the subject scales of cities and districts of the region, indicators of the possibility of relocation of a certain amount of the evacuated population by types of support and indicators characterizing the impact on the district’s resources during resettlement of a certain amount of the evacuated population are determined. It was concluded that the use of integrated indicators allows the selection of areas to accommodate the evacuated population without the use of statistical data, in conditions of incomplete and inaccurate information. The presented method does not replace traditional methods based on classical methods of territory assessment by the level of life sustenance, but also allows their reasonable combination with the experience of specialists in this field, taking into account the incompleteness, uncertainty, and inconsistency of the initial data of the study area, which does not allow the application of existing methods.

Purpose This paper aims to examine the challenges to sustaining corporate culture in a world of hybrid working. Design/methodology/approach This paper is a review of current literature on the impact of remote and hybrid working on white-collar employees. Findings There is little consensus on whether remote/hybrid working will harm or strengthen corporate culture. Research limitations/implications The viewpoint is a subjective assessment of a limited number of articles on the subject Practical implications It is not entirely clear how those responsible for corporate culture can act on the findings. Social implications In a world in which corporations are experiencing a shortage of talent, how they handle corporate culture will be increasingly important. Originality/value While much has been written on the impact of remote working, this viewpoint takes the original view that strong corporate cultures rely more on the attitudes and actions of individual employees that company programs or initiatives.

Abstract: Cloud computing has experienced significant growth in the recent years owing to the various advantages it provides such as 24/7 availability, quick provisioning of resources, easy scalability to name a few. Virtualization is the backbone of cloud computing. Virtual Machines (VMs) are created and executed by a software called Virtual Machine Monitor (VMM) or the hypervisor. It separates compute environments from the actual physical infrastructure. A disk image file representing a single virtual machine is created on the hypervisor’s file system. In this paper, we analysed the runtime performance of multiple different disk image file formats. The analysis comprises of four different parameters of performance namely- bandwidth, latency, input-output operations performed per second (IOPS) and power consumption. The impact of the hypervisor’s block and file sizes is also analysed for the different file formats. The paper aims to act as a reference for the reader in choosing the most appropriate disk file image format for their use case based on the performance comparisons made between different disk image file formats on two different hypervisors – KVM and VirtualBox. Keywords: Virtualization, Virtual disk formats, Cloud computing, fio, KVM, virt-manager, powerstat, VirtualBox.

This article examines team conflict in project management. A study of the current literature, the focus of the bodies of knowledge and the perspective of managers in Colombia is presented. Information is collected through a questionnaire about the impact of sources, types of conflicts, dispute resolution mechanisms and progress reports on the final performance of projects carried out recently by the interviewees. The importance of conflict resolution has been validated as a success factor in the management and performance of projects. The chapter aims to increase researcher interest in the subject, as well as to encourage the development and implementation of methodological tools, in order to achieve better results in the implementation and success of projects.

Rapid Transition

The emergence of cloud computing has changed perception of all regarding software delivery, development models and infrastructure. Cloud computing has a potential of providing elastic, easily manageable, powerful and cost effective solutions. The rapid transition to cloud computing has fueled concerns on the security issues. The migration of the user’s data and applications in a shared environment of a cloud, where there is a collocation of several users increases security related concerns. Several research efforts have been made in evaluating challenges related to security faced by the cloud computing environments, a number of solutions of such problems have also been proposed. Integrated security solutions should be devised to deal with the increasing security risks. In this paper, a detailed cloud computing survey, key services and concepts are being presented.  This paper attempts to evaluate various security threats to cloud computing and a number of security solutions have also been discussed. Furthermore, a brief view of the cloud security regulatory bodies and compliance have also been presented. Despite the research efforts in cloud security field, there are still some open research problems and challenges which are discussed in this paper.

The subject of the research is the approach to the possibility of using the Solow model to perform the regression analysis on the example of the Ukrainian economy model. The purpose of writing this article is to investigate the notion of regres- sion analysis, Solow’s economy model, algorithm for performing regression analy- sis on the example of Ukraine’s economy model. This model can be adapted for the economy of enterprises. Methodology. The research methodology is system-struc- tural and comparative analyzes (to study the structure of GDP); monograph (when studying methods of regression analysis on the example of the Ukrainian economy); economic analysis (when assessing the impact of factors on Ukraine’s GDP). The scientific novelty consists the features of the use of the Solow model on the ex- ample of Ukrainian economy are determined. An algorithm for calculating the basic parameters of a model using the Excel application package is disclosed. The main recommendations on the development of the national economy and economic growth through the use of macroeconomic instruments are given. Conclusions. The use of the Solow model enables forecasting and analysis. The results obtained re- vealed the problem of low resource return of capital as a resource, along with the means of macroeconomic regulation of the investment process, using which can improve the situation. A special place in these funds belongs to the accelerated depreciation and interest rate policies.
