What is it?

Golden (2007) explains it as the art or craftsmanship of creating a non-physical or virtual resource in a form of a server, operating system or any computer related physical component. Portnoy (2012) interprets virtualisation being the creation of a function of an object which would be simulated or replicated in a software similar to that of the original physical object, further stating the object could be a storage, file or desktop. Singh and Yip (2017) describe it as the process of creating a software based project or representation of something, which can be in a form of a file or any computer related object.

Purpose of Virtualisation

Golden and Portnoy (2012) both refer that virtualisation was invented or created with its purpose or main goal to help people or businesses; big or small in managing workloads by changing/ transforming traditional computing to make it easier to use, accessible to everyone or more scalable.

Benefits of implementing virtualisation in an organization

Singh and Yip (2017) state that due to limitations of traditional technologies as servers, organizations would be forced to buy new servers and other technologies, thus costing the firm a lot of money and inefficiency due to each server or computer running at a different level and this can also cause poor data or inaccurate data. The only way to fix all these problem; would be to introduce virtualisation.

They is a reduction in organization’s expenses/operating cost: Singh and Yip (2017) say that with virtualisation they would not be need for more money to be spent on buying more servers since many programs or virtual systems can be run on one server and thus the computers of the organization can use one server at the same time.

They is an increase in organization’s efficiency: IBM (2007), states they would be an increase in efficiency of the organization due to that the systems of the organization run at the same level since they use one server where many programs or virtual systems are run at the same time unlike when they use different servers they would run at different levels and result in inefficiency in the organization.

Data management is made easier or simplified: Golden (2007) says that with all virtual systems or programs of an organization running on one single server, makes it easier to manage data, in the sense that if a specific data is corrupted, the user knows which specific file is the data stored without struggling since data is organized in one server unlike when they are many servers, were one has to look for that specific server with corrupted information which can take a long time to do.

They is a decrease in energy consumption at the organization: Portnoy (2012) further says that with virtual systems or programs for the organization running on one server help in reduction in energy consumption since they are not a lot of servers running or being used which could be consuming energy in form of electricity, thus saving energy and money for the organization.

They would be an increase in productivity: Portnoy (2012) explains that with programs running on one server, they is more time for employees for the organization to do work and be productive since they is no worry about many servers being checked if they are running or working, because if one server with all the programs is running, the systems of the organization would show for all computers.

Challenges Faced by Organizations Implementing Virtualization

IBM (2007) states the challenges for organizations trying to implement virtualization is:

They is a need for bigger network storage: IBM (2007) says some system to go virtual would need a network storage as Sans, which is expensive for small organizations trying to move from traditional servers to virtual servers.

They is a need for skilled people as administrators: IBM (2007) states organizations would need to hire skilled people who are experienced with virtual machines which would be part of virtualisation. This would be a challenge since the company would either spend money hiring new employees or retraining employees.

They would be a decrease in productivity: IBM (2007) states they would be a decrease in productivity since employees would be trained about virtualisation, thus leaving less time to do work.

They would be need for licenses: IBM (2007) states that unlike traditional servers, virtual servers and other virtualisation process, they need licenses and licenses make the virtual systems work. They are expensive since the firm would pay yearly for it since expires and costing more than traditional technology.

Generation 1 versus Generation 2 virtual machine

Booth et al. (2013) state that generation 1 virtual machine allows users to pick the operating system of their choice to run the virtual machine on while generation 2 virtual machine does not allow that but uses a specific operating system for that.

Booth et al. (2013) further says that generation 1 virtual machine supports the user’s preferred boot method while generation 2 does not.

Booth et al. (2013) explains that generation 2 virtual machine has a larger boot volume unlike generation 1 virtual machine which is small. Maximum volume for generation 2 is 64 terabyte (TB) while for generation 1 is 2 terabyte (TB).

Generation 1 virtual machine is the best appropriate generation for the nesco academy because in terms of boot volume is 2 TB, which is fine since is the appropriate size to use to teach juniors about visualization, since they do not need a lot of space. Generation 2 volume space is for professionals doing a lot of work, while juniors are learning; so, generation 1 is the best. Generation 1 allows for different operating to be used, in the case of training juniors is great since I may pick the operating system I see suitable for juniors to understand or find it easier while generation 2 comes with a fixed operating system, which may be hard for juniors. Generation 1 allows different boot methods to be used by users unlike generation 2 which uses a specific one which is mostly for experienced administrators. So Generation 1 wins and is the one to be used for juniors at nesco academy.

Windows server 2008 r2 versus Windows server 2012 r2

Russel and Zacker state that the main differences between Windows server 2008 r2 which was released on July 22 2009 as a successor to windows server 2008 and Windows server 2012 r2 released 2013 as well as a successor to its previous counterpart Windows server 2012 are:

Storage support: Russel and Zacker explain that with the previous version windows server 2008 r2 it had only a storage volume of 2 terabyte which at the time when released was something for small businesses since with that memory, small business could create virtual machines up to 1 000 only which was not enough for large businesses as Adobe systems. While the newer version windows server 2012 r2 had a storage memory volume at 4 terabyte and enabled a creation of 4 000 virtual machines which was enough for big business and could respond to the user’s actions quickly.

Automatic backup or save: Russel and Zacker state with 2008 r2 they was no automatic backup but only a method of duplication of a virtual machine which was a problem since the user would not know which virtual machine was up to date and this was a waste of time, as well as waste of storage for companies. This would be fixed with the removal of duplication method and introduction of automatic backup and save in 2012 r2 server. The 2012 r2 server would save data as the user inputs the data and backup the data, so that if an accident as power cut happens, the user can still find data they left when power comes back and they do not start again from scratch inputting data, thus also saving time for production and space in terms of memory since they is no duplication method being used.

Access of system and security: Russel and Zacker state that 2008 r2 server did not have direct access for users who wanted to access their virtual machine since would access the system with same password then look for their account which would take long and they would be forced to use same password used by everyone which was not safe since anybody could access their virtual machine and also delete them; this was a security problem for 2008 r2 server. The problem for accessibility and security was solved in 2012 r2 server. The user could access their virtual machine directly without trying to search it in a list of machines by spotting it by its name since when creating a virtual machine it is a must to give it a name in 2012 r2 server which was not possible in 2008 r2 server. The user could change the default password for their virtual machine, so that unauthorised personnel could not access it but authorised people who have the password and it could not be deleted since, the user would need a password to be placed first to delete the virtual machine. This was a security measure put in placed. Russel and Zacker state that from all the major differences between the two systems the windows server 2012 r2 is the appropriate system to be used for business or educational purpose, so from the above differences it is the right one to be used at the nesco academy, to teach juniors.
