Course: Cloud Computing (ITS-532-M30) Week 7 Assignment Submit a Word document that addresses each of the following: Chapter 8Define and describe virtualization.Defend the following statement: Virtual

Desktop: This form of virtualization separates the environment of the desktop for physical devices and they are configured and virtual desktop infrastructure. Thus people are able to access their personal files and application on any internet-connected device from any geographical location.

Hardware: This is among the most common form of virtualization where a hypervisor is used to create virtual computer versions and operating systems. They are then consolidated into one large server thus all resources are used efficiently. Different OS can be run on one computer at once. Network: When it is implemented, all equipment for physical networking is combined into a single software-based resource. This is made successful by dividing all available bandwidth to several independent channels. They are then assigned devices and servers when required which is mainly used by large businesses to ensure their systems are always running.

Storage: this is the cheapest and easiest form of virtualization since all the physical hard drives are just compiled into one cluster. This is usable during the recovery process after a disaster since backup one a single cluster is easier.

Q 4 List the pros and cons of virtualization Pros of virtualization. Available at all times This means that virtualization allows virtual instances to be available all the time. It can also move the virtual instances from one server location to the other. It also ensures during migration the data is not lost; hence your virtual instance will be running at all times. Uses hardware efficiently Businesses should use this technology to apply different OS for the same computer to achieve the maximum value. Therefore, this can save the cost of hardware and ensure there is a high-efficiency level. Recovery is easy Even with new tools available that provide real-time data backup, data cannot be lost at any point in time. In case of system failure, they can continue on the last saved position and display it on another virtual machine then run it. This will ensure there is a continuous flow of the organization, thus high efficiency. (Arpaci, I, 2016). Quick and easy setup. Using this software takes less time and it comes with pre-configurations that are easier to install. Cloud migration is easier. Many businesses have been using old methods even today because they had a substantial investment which ensures the IT systems run as required. Cons of virtualization. Data can be at risk: Working in virtual instances can leave your data to be at risk in such a way that it can be accessed by unauthorized people. A service provider should have adequate security to protect data and virtual instances. High initial investment: Virtualization helps organizations to reduce the cost of operations, but the initial cost is high. Organizations need a year before to break even after realizing they have a higher profit with virtualization.

Unintended server sprawl: This is the main cause of users that look alike and many server admins. The service desk person uses a server sprawl. 4 4 5 5 4 6 4 7 8 5 4 Setting up a server and physical systems consume a lot of time and resources.

Quick scalability: Scaling on virtualization is a challenge if it has to be done in a short period of time. In case of setting up physical servers, new hardware should be set up thus bringing up some initial setup.

Performance failure: Virtualization enables the organization to utilize its resources maximally. This becomes a challenge because in case one needs an additional resource; they may not be available. Q 5 Some of the characteristics of applications that cannot be virtualized include the following When theapplication istransaction-intensive: this isbecause background memoriesarerequired andhigh peak bandwidth Theyprocess highvolumes ofdata which 10/11/2020 Originality Report https://ucumberlands.blackboard.com/webapps/mdb-sa-BB5a31b16bb2c48/originalityReport/ultra?attemptId=931dde6a-89c5-4ce2-8a58-53b21ab40b … 3/7 When the application is transaction intensive: this is because background memories are required and high peak bandwidth. They process high volumes of data which is also called big data and virtualizing such applications may make the organization prone to cyber-attacks. (Nicolae, B, 2016). The large database servers and data warehouse applications. These applications also are used for the transfer of huge amounts of data which is dangerous for the organization to virtualize since it is prone to cyber-attacks.

The applications that are not certified to run by VMware. Applications with these characteristics should not be virtualized since it is illegal. Q 6 These are some of the reasons why companies should virtualize, Growth opportunities for IT staff.

Virtualization enables IT staff to spend less time on their routine work and spend more time on strategic development.

Lowered capital and operational cost Many companies adopted virtualization because it enables them to increase savings thus lowering the cost of operation and the cost used to run the business.

Improved application availability With virtual servers, an application can be readily available and can be moved from one company to another to ensure everything is running well. And in case the problem arises, it can be identified easily due to centralization.

Better response time.

Helps the provisioning of a virtual machine to take a shorter time in improving applications. Self-provisioning by users at implementation levels is even possible. Redeployment and reduction of machines.

The reduction of machines in an organization through virtualization reduces the burden on IT management. Q7 Blade servers have the following benefits: · They are extremely small, therefore readily available in the market. This benefits even those who have small space and strong computing needs. · They offer expansion through cards. Blade servers use expansion slots to provide I/O expansion solutions, therefore hey also expand cars as a feature. · They offer easy installation options. A blade server is used when adding a new server to the mix by sliding it to the slot and wiring up. Their size also makes it possible for installation. · They require less cabling. Their small size makes it easy to create an installation with less cabling compared to other types of servers. Blade server makes the work easier by ensuring the room is well organized and by reducing the cost of repair. · They offer a centralized system of management. They are connected through a single interface thus monitoring job allocation becomes easier. Q8 Hypervisor A hypervisor is a software that runs and creates a virtual machine. It allows the main computer to support others by ensuring that some resources such as memory are shared virtually. They can include a hardware, firmware or software for creation and running machines virtually. The operating system of the guest is presented with a virtual operating platform that is able to manage several exceptions of guest's operating systems. Q9 Green computing Green computing is a term used to ensure that computers are not only eco-friendly but also responsible for the environment. It involves using computers in the right ways so that they can reduce negative effects on the environment. Computers should be disposed of in the right manner or recycled if possible; they should consume less electric power and emit less poisonous gases to the environment. The current trend of green computing is where Microsoft has submerged its systems in the sea to cut costs of cooling systems and developing systems that use solar power and not fossil fuels or electric power. (Mo, Y, 2019). Q10 Concept of the desktop on demand It is a form of technology that hosts desktops to the cloud. The user is able to access their desktop from any geographical location at any time of the day. It has significantly reduced the costs spent on IT infrastructure. Because purchasing new hardware and licensing, it is relatively expensive, especially for Desktop on demand is a replication of desktop windows with information hosted in the cloud. All business data and applications are readily available across any device and at any time. (Rao, B. T, 2016). These are the benefits of using a desktop on-demand, · Flexible working: Since your desktop is managed on the cloud, you can be able to access your desktop on any device and from anywhere at any time. · Security: Desktop on demand operates under security to ensure that customer's privacy is exercised. 4 9 10 8 10 10 8 This gives customers a lot of confidence that their data is safe.

· Real-time reporting: This allows you to organize reports on downtime, employee usage and monitoring performance. · Green technology reduces the need for hardware and servers. There will be less demand for the replacement of hardware which saves the environmental usage of power. · They save space, which ensures there is large floor space therefore no need for hiring another office space. · One can work remotely from any geographical location since their desktops are connected to any device. 10/11/2020 Originality Report https://ucumberlands.blackboard.com/webapps/mdb-sa-BB5a31b16bb2c48/originalityReport/ultra?attemptId=931dde6a-89c5-4ce2-8a58-53b21ab40b … 4/7 Source Matches  (32) My paper 95 % My paper 100 % My paper 100 % My paper 100 % Student paper 100 % Student paper 100 % Student paper 85 % Student paper 63 % · It has high speeds.
