Hello,

I need two responses of at least 150 words each for the below students discussions for this week. Also in the bold below are the questions the students at answering.

1) List and describe 5 advantages and disadvantages of virtualization.

Student one:

Still wondering if Virtual systems are a good idea. I like that there are interesting pros and cons to both sides. Sorry, the print is a little screwy.

Before going into the various advantages and disadvantages of visualization, it’s important to know what it is and what it’s used for. Techopedia’s definition of virtualization is the conception of virtual resource (servers, desktops, operating system, file, storage or networks) used to manage workloads by radically transforming traditional computing to make it more scalable. (Virtualization, 2019) Out of the different forms of visualization, the one most used is the operating system-level. This level allows the technician to manage many operating systems on one piece of hardware.

Advantages:

1. It’s cheaper to use: – Because you are using a “virtual” reality rather than having to install actual hardware it costs less to operate. All that is needed is a purchased license or the ability to access a “third-party provider” and you can get to work.

2. It allows the costs to be predictable – Because the third party individuals will be providing the virtual network, the company using it will have a better idea of what their IT technology will cost.

3. The company’s workload will be less –The virtual network will deliver automatic updates for the hardware and software it’s using, which is provided by the third party lessening the work for the IT technician.

1. Uptime has improved – Some providers offer an uptime that is 99.9999%. Even budget-friendly providers offer uptime at 99.99% today. (Aryes, 2019)

5. The deployment of resources is faster – Because the IT techs don’t have to set up the physical machines, networks or install information on the machine, it takes less time to deploy the network.

6. It allows individuals to become digital entrepreneurs. –Due to the different types of platforms that a virtual network can offer, an ordinary person can set up an online business to make money online.
7. It allows a corporation to save money on energy – Because there isn’t any hardware being used, especially those that ingest a lot of power in order to be able to run, and need high energy cooling system to keep from burning out, it saves a company on their energy bills.

The Disadvantages of Virtualization

1. The cost for the providers can be high – The third party providers will have to purchase the hardware, software and other devices to get the system up and running as well as keep it in running order.
2. There can still be problems – Applications don’t always work on every environment. In this case, there will have to be allowances made to make sure that the company can still have the software it needs to function.

3. There are certain security risks – There is a greater chance that a virtual system will be hit by a hacker and suffer a data breach. The odds of experiencing a data breach while using virtualization? 1 in 4. (Aryes, 2019)

4. There are availability issues – Because the virtual network is controlled by an outside party, there could be issues dealing with what would happen if the work that needed to be reached couldn’t be.

5. There could be issues with a company’s size – As a company grows and becomes more productive, their network should be able to grow as well. Because the virtual network is run by a third party the ability to add to the network may not be there.

6. It requires several links in a chain that must work together cohesively. – When a company has their network within the boundaries of the company, they have full control. With a virtual system, there are “several links must work together to perform the same task.” If something isn’t working correctly then what needs to be done (saving a file) may not work. (Aryes 2019).

7. It takes longer to do what needs to be done. – With a virtual environment, there are extra steps to get something done that wouldn’t be needed if the network was part of the company. (Ayres, 2019).

Student two:

This week we will list and describe five advantages and disadvantages of virtualization.

Advantages

1. Cost savings. The cost savings of virtualization versus using a server farm are greatly reduced from an energy usage perspective and also from building/location costs.
2. Business Continuity. Virtualization with a well known reliable company ensures that your business can run with minimal downtime. This also ensures all users will have access when and where they need it.
3. Efficiency. You can increase the efficiency of workers by allowing them to work remotely which in turn saves them travel time and gives more work time with less stress.
4. Better Backups and Disaster Recovery. Backups and Recovery are handled by another party potentially saving your IT department many hours as well as minimizing downtime by including redundancy into the mix.
5. Less Environmental Impact. Not needing to have dedicated facilities reduces your carbon footprint and also reduces electrical costs of running a server farm.

Disadvantages

1. Potential Upfront Costs. Depending on company size the hardware costs could be quite extensive during initial setup.
2. Licensing. Licensing costs for a quality product could potentially consume a smaller business’s IT budget. Using a different product may save money but at what cost of service degradation.
3. User Training. The learning curve and training for the entire staff could be a logistical nightmare depending on the company layout globally. Retraining and additional education could slow usage/continuity tremendously during the first six months.
4. Application Compatibility. Depending on the company and software requirements, not all applications work well or at all in a virtual environment increasing downtime or cost of upgrading and transitioning to an entire new software suite.
5. Availability. Depending on your choice of virtualization the availability may suffer during times of heavy usage or during a disaster. This really depends on the service you choose and the cost versus your budget.

We could list many more for each side, but the decision truly comes down to the type of business and what is cost effective. Deployability is also a concern if a business has many remote users who would require assistance for start up and support.
