An analysis of Approaches for Desktop Virtualization and Challenges

In the Information Technology world, cloud computing technology offering unlimited amount of IT resources and services to end users over the internet on pay-per-use basis. End users are accessing the cloud services on their mobile or personal computers. Service providers are upgrading their services very frequently to enhance the services, and to use their upgraded services, end users are also required to update the specification of their devices. But it will be very costly for the end users to upgrade their devices for high specification to use the enhanced services. Desktop Virtualization is an extensive technology of cloud services. It is the new concept, in which users can access the virtual desktop of required specifications, software and operating system on their old devices anytime and anywhere. With the help of desktop virtualization, users will be benefited by avoiding the cost of frequent upgradation of mobile or personal computer system. Desktop virtualization technology is proving to be a boon for large and small organizations who have to upgrade their computer system with new technology, which is a very costly and challenging process. Desktop virtualization avoids upgrading the hardware of the client machine repeatedly. It allows us to access all applications and data at a low cost on our old machine. This paper presents the comparative analysis of various approaches for desktop virtualization and various challenges which required the solution. Analysis presented in paper has been done based on various performance parameters which will provide the end users low-cost cloud services and best performance on their mobile or personal computers.

Application of Desktop Computing Technology Based on Cloud Computing

With the development of internet technology and computer technology, in order to solve the big data problem in the new era, cloud computing has emerged at the historic moment. Desktop virtualization, as an important application of cloud computing, has experienced unprecedented development. Although traditional virtual desktop solutions can solve the problem of PCs, they cannot be used for centralized distributed cluster deployment, and they mostly rely on the underlying virtualization technology. The dynamic management of virtual machines is mainly to take into account the goals of QoS, resource utilization balance, and power under the premise of ensuring the user experience, the maximum guarantee of the balance of host resource utilization, and the reduction of power consumption of the entire system. The results show that by deploying a test desktop virtualization system, this article reduces the power consumption of host resources, reduces the SLA violation rate (improves the user experience), and improves the balance of host resource utilization.

VIRTUAL DESKTOP INFRASTRUCTURE IN HIGHER EDUCATION INSTITUTION: AN APPLICATION OF HOME AND MOBILE COMPUTING ENVIRONMENT

Currently, universities have rising demands to apply the incredible recent developments in computer technology that support students to achieve skills necessary for developing applied critical thinking in the contexts of online society. Medical and engineering subjects’ practical learning and education scenarios are crucial to attain a set of competencies and applied skills. These recent developments allow sharing and resource allocation, which brings savings and maximize use, and therefore offer centralized management, increased security, and scalability. This paper describes the implantation of Virtual Desktop Infrastructure (VDI) to access the virtual laboratories that bring efficient use of resources as one of Al Balqa Applied University’s (BAU) Private Cloud services. The concept of desktop virtualization implements the sharing of capabilities utilizing legacy machines, which reduces the cost of infrastructure and introduces increased security, mobility, scalability, agility, and high availability. Al Balqa Applied University uses the service extensively to facilitate in/off-campus learning, teaching, and administrative activities and continue performing their work and education functions remotely to cope with the COVID-19 pandemic.
