1: Individually describe the value of virtualization and server farms to large organization.
Values of Server Farms:
Server farm is a place where huge amount of servers are placed and are connected via fiber optics. It is significant for the large organizations and companies to increase the computer processing capability so that they are able to meet the increasing demand of sharing the data resources.
If we talk about the server farms, they need large amount of electricity, cooling systems and many other appliances. Most of the companies or organizations build it after getting the most favourable location to gain the advantage of less expensive hydro-electric power like all the other big companies (Google, Yahoo, Microsoft). The main advantage is, if any server fails to perform at any time, the task executing on it is automatically transferred to another server (Kakkar, Devika, 2018).
Values of Virtualization:
Virtualization is defined as the process of assigning tasks to the server by partitioning the server into different virtual servers. These virtual servers are known as VM (Virtual Machines). Virtualization allows the applications to run in their own functioning environment.
In real, physical servers are very few in number but each physical server is further divided into many virtual servers. That’s how they work together as a massive number of servers at low cost, consuming minimum energy, occupying less space in the data center, using fewer cooling appliances and less quantity of employees. This also affects the maintainace cost.
Moreover quick upgradation in the systems as the demand changes. Emphasis on the facilities which are provided by the technology (Millenson,Michael, 2017).

2: If you were the chief information officer of a firm, how would you explain the workings, limitations, and advantages of cloud computing.
Being the CIO of a firm, I would have explained the working, limitations and advantages of the cloud as,
To understand the working of the cloud, first of all we need to know what cloud computing is. The cloud has been used as a metaphor for the internet. If we notice, the cloud sign in diagrams is actually the sign of internet connectivity. It is like a virtual space that connects all the users across the globe. Cloud is a way of sharing information from one computer to another via satellite networks. Cloud consists of frontend and backend section. The front side is the client side of the system while the backend is the cloud section of the system. Connected to each other via internet. (Zaharia,Adrian,Ioan,2017)
Benefits of Cloud Computing:
- It provides us the worldwide access of the data we have.
- It is accessable on any devices (Computer, Laptop, Tablet, Smartphone).
- It provides us more storage than we have in our devices.
- It is easy to use and set up.
- It automatically updates making it easier for the user.
- It has reduced cost of storage devices.
Limitations of Cloud Computing
- There are chances of security breach in cloud computing
- Privacy is compromised, some intruder may access the information
- Internet availability is an issue, sometime we don’t have internet connectivity.
