Introduction

· In the recent past, organizations through visualization of computer servers have been able to run computer applications on multiple servers without having to purchase extra hardware (Jain & Choudhary, 2016).

· Several applications whose processing power is low are consolidated into one server hence enabling the company to save space.

· Programmers can test new operating systems without interfering with other applications through the independent systems offered by virtual servers (Nagesh et al, 2017).

· Network administrators can also create virtual hardware through the creation of legacy systems.

· Programs will still operate as they would on old hardware thus giving organizations easier transition to new processes free of hardware complications.

· Migration, which was only possible on physical machines that used the same hardware, has been made possible by server virtualization (Rao & Rao, 2015).

· Now servers can move even if both have different processors because of virtual migration provided they are from the same manufacturer.

· Through desktop virtualization, unnecessary hardware has been eliminated while at the same time maintaining the expected performance.

· There is no need to download information through the device because cloud storage technology ensures that this information is stored in the cloud.

· Secure access to the server is also guaranteed through an application in the device known as a gateway (Ma et al, 2015).

Types of Server Virtualization

· In cloud computing, there are three types of server virtualization: Hypervisor, Para-Virtualization, and full virtualization (Tamane, 2015).

· The hypervisor allows the device to operate multiple systems by performing tasks like managing queues, returning requests on hardware, and posting (Jung et al, 2015).

· Para-Virtualization is connected to the Hypervisor and it increases the overall performance of the guests operating system by linking it to the hypervisor.

· Full virtualization works just the same way Para-Virtualization does.

· Each virtual server is unique and runs its operating system (Tamane, 2015).

· A physical server is converted to multiple servers by an administrator present in the software designed especially for this purpose.

· To operate efficiently and effectively, virtual servers should commit to a particular task (Ma et al, 2015).

Advantages of Server Virtualization

· The implementation of visual servers allows one server to hold more than one machine thus increasing the utilization of the hardware (Motochi et al, 2017).

· Each virtual machine on the physical server manages the computer applications and therefore they do not have to use their servers.

· According to Tamane (2015), IT departments implementing the data virtualization strategy save 40% in the costs of their hardware and software.

· Server virtualization allows fast provisioning and deployment of systems.

· This in turn saves IT departments' time to install physical servers by cloning existing virtual machines.

· Server virtualization allows a machine to move safely and quickly from one server to another (Tamane, 2015).

· There is a fast and effective back-up of information and data can be retrieved anytime.

· The migration of servers has left organizations with fewer servers thus reducing their costs of power and cooling.

· According to Tamame (2015), consolidation has helped organizations reduce their energy costs by 80%.

· The reduction of physical servers has led to a consequent reduction in maintenance therefore IT staff can focus more on productivity.

· The fact that each virtual server runs its operating system and performs complex tasks has greatly benefited the IT industry (Motochi et al, 2017).

Impact of Server Virtualization on Healthcare

· Server virtualization has impacted health care organizations by ensuring that medical records are accessed effectively and efficiently (He et al, 2015).

· Through server virtualization, IT staff for hospitals can come up with a communication channel to exchange health information easily and efficiently.

· Users can now get a privacy clearance set up by IT professionals to access information from the same server thus ensuring that data is well protected (He et al, 2015).

· Access and sharing of information through the Electronic Health Records (EHR) have been made easy through server virtualization.

· Server virtualization will enhance doctor-patient interactions because the doctor can access patient information at any time (Godbole & Lamb, 2015).

· To ensure that operations in health facilities are effective, IT experts will need to monitor the cloud to ensure that the server is properly maintained and any loop corrected (Chuang & Chen, 2017).
