The Information Technology (IT) industry has always been structured in a manner that enhances improvement on its services and computing powers with minimal infrastructural acquisition, personnel training, or licensing new software (Knorr and Gruman, 2011). One technology that has been employed in the achievement of this endeavor is the use and creation of cloud computing. Cloud computing is a term that was coined as a metaphor representing the infrastructural network being used by myriads of computers and servers. This term has also been described differently based on its user application, infrastructure using it and supplying the services (Vaquero, Rodero-Merino, Caceres, & Lindner, 2009). This paper explores the definition of cloud computing, its myriads of application in the IT industry, its advantages, histories, development, its future, and issues affecting it.
Definition
Based on the payment system, cloud computing is defined as a pay-per-user or subscription based service that broadens its current capabilities and structures. In the networking field, cloud computing is comparable to grid computing, where computers in a network with idle processing cycles are harnessed to work out problems or issues that are too exhaustive for accomplishment by a single machine (Knorr and Gruman, 2011). In cloud computing, the shared IT infrastructure involves a network of servers that operate through virtualization to perform high quality and highly intensive computing processes and tasks. Using web terminology, cloud computing is the storage and data processing via the use of a web browser, rather than the direct use of the personal computer or office server. Therefore, it can be described as the provision and acquisition of information, ...

...d to the 1950s during the use of large mainframe computers by schools and corporations. The hardware infrastructure for the gargantuan mainframe would be stored in a single space where multiple users could access it via ‘dumb or static terminals’. This central mainframe was structured in a manner that ensured maximum use through sharing physical access and CPU time during periods of inactivity. In the 1970s, IBM introduced the VM operating software that facilitated administrator with multiple virtual systems in one physical mode. This allowed multiple individual computer environments to be sustainable in the same physical environment, which is considered as the cradle for most virtualization software. The shared resources in the VM operating systems allowed for custom or guest operating systems with their own keyboards, memory, hard drives, CD-ROMs, and networking.
Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access

A Brief History of Unix This document is designed to give people with no previous UNIX experience some sense of what UNIX is. This document will cover the history of UNIX and an introduction to UNIX. HISTORY OF UNIX AND CAUSES FOR ITS POPULARITY Most discussions of UNIX begin with the history of UNIX without explaining why the history of UNIX is important to understanding UNIX. The remainder of this document will describe some strengths and weaknesses of UNIX and attempt to explain why UNIX is becoming popular. All of UNIX's strengths and weaknesses can be directly related to the history of its development, hence a discussion of history is very useful.
The textbox explains virtualization in a long technical description but virtualization is basically running another existences inside something. Virtualization is a very “complex and fun” topic in technology because it’s not a physical item but can be manipulated by physical things. The internet could be consider to be virtualization because it is not a physical thing but an abstract intangible object. When people ask me what virtualization is, the first thing that comes to my mind is the movie The Matrix and the movie Inception. Both film have an plot that exist inside a “virtualization”, The Matrix is a simulation running on computers just like how we can combine computers to act as one and run programs like “The Matrix”. The movie Inception is a perfect example of virtualization because you can run an OS inside an OS inside another OS just like in the movie where they go deep into dreams. Virtualization is basically having multiple intangible items house in one physical item.
Cloud computing is the transfer of computing data or information into Internet. Cloud computing services allows individuals and businesses to
Cloud computing is a model for enabling convenient, on demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. This cloud model promotes availability and is composed of five essential characteristics, three service models, and four deployment models.
My purpose behind this brief history of virtualization was to inform you how virtualization became I have a proposal for you. I would like
Then came Linus Benedict Torvalds. At the time he was a sophomore majoring in Computer Science at the University of Helsinki, his hobby also included computer programming. At 21 he found himself spending most of his time toying with computer systems, trying to see what he could do in order to push their limits and increase their functionality. The key missing in his tests was an operating system that had the flexibility craved for by professionals. MINIX was available, though it was still just a stu...
The notion of Cloud computing has not only reshaped the field of distributed systems but also undamentally changed how businesses utilize computing today. While Cloud computing provides many advanced features, it still has some shortcomings such as the relatively high operating cost
There per 1947, when the transistor was invented, and when Jaquard (1804) designed a loom that performed predefined tasks through feeding punched cards into a reading contraption; nobody imagined how quickly that it would take to get the nowadays supercomputers.

The fundamental idea behind a virtual machine is to remove the hardware of a single computer and make it a self-contained operating environment that behaves as it is a separate computer. Essentially, the virtual machine is software that executes an application and isolates it from the actual operating system and hardware. CPU scheduling and virtual-memory techniques are used so that an operating system can create the illusion that a process has its own processor with its own (virtual) memory. The virtual machine provides the ability to share the same hardware yet run several different operating systems concurrently, as shown in Figure 2-11.
The computer evolution has been an amazing one. There have been astonishing achievements in the computer industry, which dates back almost 2000 years. The earliest existence of the computer dates back to the first century, but the electronic computer has only been around for over a half-century. Throughout the last 40 years computers have changed drastically. They have greatly impacted the American lifestyle. A computer can be found in nearly every business and one out of every two households (Hall, 156). Our Society relies critically on computers for almost all of their daily operations and processes. Only once in a lifetime will a new invention like the computer come about.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
Cloud computing is the progression of other computing technologies such as paral-lel computing, distributed computing, and grid computing. Its main principle is to disseminate the computing grind stones to distributed computers. Majority of us still use the PC’s and laptops to cache the data and files, sharing of data and files, and to send emails. If our pc’s diverse...
