Virtualization and the Cloud Computing World

The popularity and rapid adoption of Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS) by a number of organizations have impacted internal IT/IS departments. These services provide a virtualization infrastructure that covers data storage, networking, desktop computing, mobile computing, and so on.

Write a 2–3 page paper in which you:

Describe at least three items that an organization’s IT/IS department should consider when an organization’s strategy calls for the use of SaaS, PaaS, or IaaS.
Evaluate the ways that SaaS, PaaS, and IaaS are used to reduce Total Cost of Ownership (TCO) and increase Return on Investment (ROI).
Examine the impact on the IT support personnel when an organization embarks on the strategy described in the first bulleted point.
Analyze three considerations that the organization’s management should be aware of.
Examine three security issues that could arise from this type of infrastructure.

Sample Solution

Dorian Gray embodies the aphorisms in the novel's preface. Endowed with "finely curved scarlet lips . . . frank blue eyes [and] crisp gold hair," Dorian possesses "all the candor of youth . . . as well as all youth's passionate purity" (18). Wilde describes Dorian's looks as if he were a work of art. People are drawn to Dorian simply because of his handsome looks. Even those who hear evil things about him cannot "believe anything to his dishonor when they [see] him" (131). To the observer, one of Dorian's immaculate looks could not possibly do anything immoral. Thus, regardless of his transgressions, Dorian escapes any consequences of his moral conduct because of his physical appearance. To see Dorian as anything but beautiful would be like viewing art through a moral perspective. But much like art itself, Dorian possesses no other traits besides his physical beauty. To this effect, he is a useless person who exists only to live a pleasurable lifestyle. Such casual living without suffering makes Dorian "the perfect type" (222) of human: flawless and without care for anything except what is beautiful. Dorian creates for himself an enviable life that seeks to live for experience alone, regardless of the consequences. He lives life on a whim, changing from one passing interest to the next whenever he pleases. Wilde suggests that Dorian deserves to be worshipped for his love of the superficial, especially by his curing "the soul by means of the senses" (189). Dorian avoids suffering by indulging in the aesthetics of life. Knowing that his beauty will last forever, Dorian triumphantly sails through life with hardly a care. Such an existence parallels the aesthetic principles laid down in Wilde's preface, which assert that the surface is all that really matters. Yet an inherent contradiction to the preface lies in the fact that Dorian eventually sees the reality that lies beneath his beautiful features, suggesting that the aesthetic lifestyle, without a thought to morality is destructive. By observing the hideous transformation of his portrait, Dorian is "corrupt without being charming" (1) since he finds "ugly meanings in beautiful things" (1). Beneath his youthful countenance lies a sinful creature capable of blackmail and murder. But Dorian at first denies this fact, continuing his quest for pleasure and allowing his soul to disintegrate further. Though the portrait acts as a moral indicator for Dorian, he blatantly disregards it. Such hatred of reality can be akin to "the rage of Caliban seeing his own face in the glass" (1). Caliban, the hideous servant from Shakespeare's The Tempest, destroys a mirror to hide from his appearance. So too, does Dorian lock his picture away and indulge in material possessions to "escape, for a season from the fear that seemed . . . almost to great to be borne" (143). Instead of curtailing his sins, Dorian prefers to live his life with the absence of morality. Yet the memory of the terrible portrait always returns to haunt him, and Dorian becomes paranoid that it will be discovered and his appearance will be tarnished to the world. Eventually, Dorian sees that "his beauty to him had been but a mask, his youth but a mockery," (223) and the full weight of his sins becomes apparent. Yet caught up in his vanity, Dorian
