What Are Benefits Of Companies Going Online And Downside?



Shifting physical machines on virtual servers and then consolidating them in something that can help organizations curb their electricity and power consumption to a large extent. The presence of few physical servers means less energy expenditure and dissipation which will also have a direct impact in enhancing the efficiency of the entire process.
Greater scope for Quality Assurance
With the concept and application of the virtualization environment greater time, resources and efforts can be dedicated to the ways through which can carry out their own experiments in their own virtually created lab environments (Marshall, 2011). This will have a positive impact on exploring new and experimental ways that can be useful and beneficial for carrying out and testing their own products by passing them through various stages of quality assurance before they can actually be released in the market or can be used on a greater level as a service.
Reduce hardware vendor dependence
The virtualization concept, since it relies on the replacement of physical hardware to virtual one, it provide data centre managers and owners a whole lot of flexibility when it comes to purchasing server equipment that they have to choose from. Moreover, relying on a single vendor and following the same server model can sometimes be frustrating for users. In that case the application and use of server virtualization is always beneficial.
Issues
Backup recovery issues
When it comes to virtualization there are frequent issues and problems that are encountered in terms of retrieving data, and hence proper backup mechanism is often a pre-requisite in cases of companies using virtualization techniques and methods. Even though many services offering virtualization offer proper backup services to their clients, they need to be updated on regular basis and come up with subscription fees that needs to be paid depending on the package being purchased and the scale of services accompanying it.
VM Sprawl
There is no doubt about the fact that the technology of data and information virtualization comes with features such as being cheap, effective and convenient to use, three qualities that you rarely find together. However, with the presence of these features we cannot sideline the fact that its easiness in terms of usage sometimes creates problems for users.
 The provision of VMs or Virtual Machines is just a click of a button and this can get out of control many times with many VMs popping all around the data centre making the management of the entire technical infrastructure and data centre difficult (Posey, 2010). This is mainly a factor that does not take place in a physical environment, but is commonly found and detected as a prominent issue when the systems and data management is switched from traditional to virtual means.
Non-supportive of many applications
It may come as a surprise for many but there are many applications that are not supported or are not compatible with the virtual environment and servers on which they are placed and deployed. A common example of one such application is in the form of Exchange Server which is only supported on physical servers and cannot be run of virtual platforms and data centers.
 Secondly there are many other applications that are only compatible on certain virtual servers and not all. Hence, when planning the switch from physical to virtual data centre and management it is important to consider these factors in the planning phase so that any problems that may occur or emerge in the future can easily be averted and avoided.
Identifying servers not functional in virtual environment
There are some servers that are simply not good and do not have the compatibility do work in a virtual environment (Search Networking, 2011). For example some applications such as those related to enterprise require special hardware along with other features in order to work in a virtual environment. In many of the cases such applications work through the usage of dongle which are never supportive or functional in a virtual environment.
Technology Position Within Industry
There remains no doubt in stating and understanding the fact that with the passage of time it is mainly the virtualization technology and usage that is going to take over the world. In its most prominent form it is the desktop virtualization that is being used widely and its applications and benefits are being manifested in various fields and sectors such as education, service sector and even manufacturing sectors.
 Equipped with features such as convenience in terms of usage, efficiency and cost cutting the technology of virtualization surely has a long way to go. However, in this discussion it is important to keep in mind that the technology of virtualization has to be considered from educational perspective and the advancements that it can introduce in the industry with time (IBM, 2012). In this context the usage of desktop virtualization has already gained immense momentum by providing students the accessibility and the facility through which they can make use of their data even if they are not physically present on their original computer, hence making data availability possible through the establishment of virtual communication channels and platforms. Nevertheless, the prospects and the opportunities being offered by this virtual environment are far more widespread and effective in terms of implementation as well as usage if they are highlighted and provided due attention.
This can be done through the employment of a concept that is known as application virtualization and through which the entire concept of virtualization and the ways through which it is applied in schools will change forever (Dell, 2010). First and foremost it is important to understand that even though desktop virtualization has created in providing students with a new environment in terms of education, there are some limitations involved in it when planning the technology on a higher level. It is precisely here when the entire model needs to be amended and requires further modification. This can be done through employing ways that make use of the state of art technology and gadgets.
We are well aware of the fact that students whether they are in high school, college or university are very well aware acquainted with the use and the techniques that are employed in handling modern day gadgets such as tablets and smartphones. It will be through the use of these devices through which virtual platforms will be established. Each class will be provided with either a smartphone or a tablet device that they can use for this purpose. The gadget being provided will be equipped with applications that are considered appropriate for the grade of students who are being provided with the device as Evernote, Paper and Goodreader (Shah, 2012).
Students will be required to use these applications and the data that they download using the device and other purposes that they use the device for will automatically record and store data in a virtual environment with the help of virtual servers that will have established connections with each of the device being used. In case if any student is unable to finish a task that is assigned to him due to the battery exhausting of the device, his or her data can easily be retrieved from the specified server with which his device is connected to.
At the same time, it is also important to state here that with the presence of such mobile and portable devices and their usage in schools and other like organizations it is important that the virtual servers being set up for connecting with each device and gadget have a greater range of data transmission since with the use of such devices in educational institutions the scope of mobility among students will definitely increase (Centre for digital education, 2012). Also, it will also be beneficial in providing students a permanent space for their data storage. In that case even if a severe case or incident such as fire or any other disaster takes place the data will still be stored within the virtual space.
