Organizations have in the recent past run similar computer applications on multiple servers without procuring extra hardware through virtualization of computer servers. This has helped reduce a significant amount of space for companies that have several servers through the consolidation of several applications with low processing power into one server running numerous virtual environments (Pearlson et.al 2020). Programmers have been offered independent systems by virtual servers, where they can test new operating systems without affecting other applications. In the future, server hardware will become out-dated. Network administrators can create legacy systems where a virtual version of the hardware is created. Programs will do as if they were still operating on the old hardware. Organizations will have easier transitions to new processes without hardware complications (Papavassiliou 2020).

Server virtualization has resulted in migration, which is the movement of a server environment from one place to another. This was only possible if the physical machines operated on the same hardware, OS and processor (Makoviy et.al 2017). Virtual migration has made it possible for the movement of servers even if both machines have unlike processors. They must however come from the same manufacturer. Technological advancement has made information accessible through smaller computer devices. Virtual machines emulate computers via special software designed for that objective. Desktop virtualization has made it possible for the elimination of unnecessary hardware while maintaining performance expected by the user. Cloud storage technology eradicates the need to download any information on the device as information is stored in the cloud. When a user logs into their computing device, they will find an application that is similar to the application in their smartphone. It is referred to as a gateway that provides secure access to the server (Yang et.al 2019).

According to Data Flair (2020), there are three types of server virtualization in cloud computing, which include Hypervisor, Para-Virtualization and full virtualization. Hypervisor gives room for operating multiple operating systems. It performs tasks such as posting, queue management and returning the hardware requests. Para-Virtualization is grounded on the hypervisor and the guests operating systems and adapted entry assembled for mounting it in a virtual machine. After modification, overall performance is increased as the guest operating systems links with the hypervisor. Full virtualization is similar to Para-virtualization Ghanwani, Subramanian & Sane 2016). Machine operation used by the operating system is further used to modify the status of the system. An unmodified operating system can run on the Hypervisor. Data Flair says that each organization will have a server that goes in line with the administrator’s needs.

Every virtual server performs like a unique physical device proficient in running its OS. A software that is precisely designed for this purpose is used and an administrator present in the software converts a physical server to multiple servers. The central processing unit (CPU) operates with multiple processors that run several tasks easily. Virtual servers commit only to a particular task to operate efficiently and effectively (Johnathan 2020).

Implementing virtualized servers increases hardware utilization as one physical server can hold multiple machines. Computer applications do not need their server as each virtual machine on the physical server manages them. According to New Horizons (2020), there has been a 40% reduction in hardware and software costs for IT departments implementing this strategy. Server virtualization also enables fast system provisioning and deployment which allows the IT department to clone existing virtual machines without spending much time on installing a new physical server. Server virtualization also allows the movement of the virtual machine from one server to another safely and quickly. Information in the cloud is backed up effectively and fast. This helps as it acts as a storage loop where data can be retrieved anytime (New Horizons 2020).

As servers are migrated, organizations are left with fewer servers. This results in reduced cooling and power costs and organizations will focus on other factors. According to New Horizons (2020), organizations have recorded a reduction in energy costs by 80% as a result of consolidation. Companies can also shut down servers without distressing applications. Fewer physical servers mean there is reduced maintenance. This makes the IT staff spend much time on productivity in ensuring servers are working effectively. Server virtualization in cloud computing has helped IT industries as each virtual server runs its operating system and is capable of performing complex tasks (Wang et.al 2017).

Health care organizations have greatly been impacted by server virtualization as it provides efficient and effective access to medical records. Server virtualization helps IT staff set up a channel of communication for hospitals to exchange health information with ease. IT professionals can set up privacy clearance for the users accessing information from the same remote server. This ensures the security of data and efficient performance for doctors and patients (HITInfrastructure 2020). Virtualization in the mobile form will assist in easy access for information shared through the Electronic Health Records (EHR).

HITInfrastructure (2020) explains that doctor-patient interaction will be improved as required information about a patient will be easily accessible at any place provided the doctor has an application on a mobile phone or a laptop. IT experts will focus on monitoring the cloud and ensuring that any loop in the server is corrected and maintained to ensure the effectiveness of operations in health facilities.
