Strayer CIS 336 Enterprise Architecture, Assignment 4: Virtualization and Cloud Computing World, Graded A, 7 pages, 785 words.
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 has 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 two to three (2-3) page paper in which you:
1. Describe at least three (3) items that an organization’s IT / IS department should consider when an organization’s strategy calls for the use of SaaS, PaaS, or IaaS.
2. Evaluate the ways that SaaS, PaaS, and IaaS are used to reduce Total Cost of Ownership (TCO) and increase Return on Investment (ROI).
3. Create SaaS, PaaS, and IaaS architectural diagrams using Microsoft Visio or an equivalent such as Dia. Note: The graphically depicted solution is not included in the required page length.
4. Examine the impact to the IT support personnel when an organization embarks on the strategy stated in Question 1.
5. Analyze three (3) considerations that the organization’s management should be aware of.
6. Examine three (3) security issues that could arise from this type of an infrastructure.
7. Use at least three (3) quality resources in this assignment.

Suppose an organization that has entered into an SLA with another organization goes out of business. Determine whether the SLA still applies or becomes invalid. Propose what the organization should do to maintain the service delivery. I believe that Service-Level Agreements (SLA) are like any other contract and are only good for as long as both or either parties are in business. If the service provider goes out of business there would be no actionable response the client could take, leaving the SLA invalid. Should the client go out of business, the service provider again would have no actionable response. Yet I believe that the service provider would notify their customers before closing their doors and would offer a substitute provider recommendation. Mainly because it’s the right thing to do, but also because other companies would pay to have access to the customer base. I would propose that the client considers the possibly that all of their vendors could at some point go out of business, or at least that a day may come that the client will need or want to change providers. As a part of their Businesses Continuity Plan they should already have an alternative provider in mind. The client should also consider how their data is stored and formatted to ensure they have access to backups and that they can import or export to other providers. I believe this makes sense because our Incident Response and Disaster Recovery Plans would cover backups for the SLA.
From thee-Activity, provide your opinion on whether or not a non-Apple device user should have the ability to use iCloud. Explain whether or not this points to the limitations of cloud computing. Determine whether businesses should consider iCloud in their cloud computing strategy for their IT needs. Support your rationale. From the viewing of thee-Activity video and the reading in our textbook about Apple’s iCloud capabilities, it is not determined that it is an option that should be made available to a non-Apple device user. The reason for this conclusion is that Apple’s iCloud Drive is merely a version of Dropbox or Google Drive for which non Apple users can utilize their devices. These options are all cloud-based storage systems that let users share files across multiple devices and apps. As to the limitations of cloud computing, that is still not fully known because iCloud is still an evolving technology. It has weaknesses like network connection (as demonstrated in the slow download speed of the document in the e-Activity video), control of data security, peripherals compatibility, and integration problems. Businesses are aware of the limitations with iCloud or cloud computing. However, they see clear benefits in shifting to cloud computing. Some companies are adopting it unconditionally while some enterprises are testing the waters by moving only non-critical applications to the cloud. Most businesses, on the other hand, want to wait and see how the technology evolves before deciding.
