Strayer CIS 336 Enterprise Architecture, Assignment 2, Telecommuting and the Mobile Worker, Graded A, 5 pages, 903 words.
The number of American telecommuters is expected to increase by 29 million telecommuters or 43% of the workforce by 2016 as more work gets performed from remote locations. Mobile workers can work from wherever they are and use the IT / IS technology necessary to access co-workers, company or corporate infrastructure, intranets, and other information sources.
Write a two to three (2-3) page paper in which you:
1. Describe the impact of telecommuting on energy conservation, IT operational costs, “green computing”, and shifts in telecommuters’ lifestyles (e.g., parents, disability, etc.).
2. Describe how the business infrastructure should be designed so that employees will be able to continue to perform business functions in the event of a disaster (i.e., storm, hurricane, or earthquake) that destroys or makes it impossible to access the buildings.
3. Determine four (4) advantages and four (4) disadvantages of telecommuting from an IT manager’s point of view. Elaborate on each advantage and disadvantage.
4. Examine the effect of Bring Your Own Device (BYOD) to the IT infrastructure with regard to security, IT support, knowledge, and data management, green computing, and telecommuting.
5. Use at least three (3) quality resources in this assignment.

With the proliferation of smart phones and intelligent computing tablets such as the iPad, enterprises are increasingly faced with employees who want to bring their own devices and connect to enterprise systems. Determine whether or not employers should allow this type of connectivity to enterprise systems. Support your reasoning with three examples. Predict the impact to an organization’s Total Cost of Ownership (TCO) when employees use BYOD.
I believe that the BYOD debate depends a lot on the company, job title and reason for the request. For example, if a sales rep is working on a presentation and they like the software on their Mac better, then why not? Same for the companies web developer, graphic designer, etc. I admit there are many jobs that it would not be a good idea for, mainly were company data or network would be at risk, but many companies allow certain job titles to work mobile and they manage the risks with VPN’s, IDS, and by educating the employee. I’m sure talks with mobile employees about security, ethics, IP and their device are already in practice. Now from the security point of view I completely agree that BYOD should not be allowed because that’s how employees bring in malware and some may want to damage or steal from the company, and some of my class mates work in secure areas for the government where you can’t even bring your phone into I the building. Those points should always be consider when a request is made. I would suggest, for some companies, strict company computer rules such as no personal email, block all web sites not needed for work, no usb port use and a clear login message that all active is logged. Then offer a separate wifi network for BYOD for brakes or lunch time. Because employees will always try to get around the systems we setup so by offering one for them they will be happier and not trying to use proxies, usb browsers, etc. I I believe TCO also depends on each example, if the BYOD is for private use then its probably a cost to the company in lost work. If its for work then its probability a gain for the company in equipment cost. Yet ifmalware is brought in or data theft occurs then it is again a cost. So in summary, for most businesses BYOD is too much of a risk to security, but in some cases, BYOD could be handled with success.
From the e-Activity, determine whether Strayer University should allow students to use BYOD on campus. Explain why or why not.
I believe Strayer should allow BYOD because education is very digital now with ebooks and ECOHOST library. Also assignments are written digitally many times with presentation slides or videos. I believe it would be too expensive to give computers to every student. I also believe if students can learn to use their phones appropriately in college they will be better off when they start working.
Suggest how an organization should choose between Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). Support your recommendation with an explanation.
SaaS-of all the cloud computing services, Software as a Services is probably one of the easiest to understand and in some cases folks and organization may be enjoying the benefit of this service without knowing that it is SaaS. A good example of this is Microsoft Windows Office 365, Apple iCloud Suite (Pages, Keynotes, Numbers), Adobe Creative Cloud, H&RBlock Web Tax Services, Business Plan, etc. All ofthese are SaaS and they are becoming more and more prominent and the norm in their utilization. In addition there is the family of customized SaaS options where a business, organization or an individual may find a need to host a suite of software application or a single application (shrink wrapped like MS Office or customized like a proprietary designed inventory system). The organization or individual may not have the capacity (hardware wise) or does not desire to purchase additional hardware to install and host the software application; thus, they chose to acquire the services of a Data Center to install and host the software application of their choosing. PaaS & IaaS-the simplest way to understand how and when to choose the need for a platform as a service or an infrastructure as a services is to ask a few key questions related to requirements: In the case ofPaaS, the key question(s) should be “Is the software application we need to install platform dependent? Or do I have a preference as to what platform I want to run my software application on?” Just a quick refresher, platform for the most part refers to operating systems (OS), i.e., Windows 2003/2008/2012, Linux Red Hat:, Ubuntu, Slackware, Oracle Unbreakable, and Solaris 8/9/10, etc.; thus the question, is the software application I need requires Windows or some other OS? If it does, then that would be one of the options in my SLA. Likewise for IaaS, one must ask a few questions: does it matter what hardware combination the data center utilizes to host my PaaS? (Also known as OS) or how much control do I want to exert/have over the environment I am implementing or is there a specific requirement needed? It is possible that the individual or the organization does not want to utilize the data center hardware and they want to bring their own (have more control) or it could be that they want a virtualized infrastructure rather than standalone architecture. In summary, it boils down to system requirements, information systems (IS) requirements, security, performance, etc., all of these play a big role in the architecting and choosing of either or both of the services PaaS or IaaS. Salesforce.com, Face book, Gmail, Windows Azure, Apple iTunes, and Linkedln are examples of applications in the cloud computing space. Examine the benefits and possible problems for these organizations when it comes to cloud computing. Propose solutions to these problems. Predict the impact to an organization’s TCO andROI
No doubt, there are innumerable benefits to utilizing the above companies to satisfy cloud computing needs. The most obvious benefit is that it eliminates the total cost of ownership (TCO) which directly could impact return on investment (ROI). By cutting cost on hardware purchase, service maintenance, not to mention the hired staff needed to maintain an Enterprise System infrastructure, one would lessened TCO, thus minimizing overhead that eventually would need to be recovered. There other obvious benefits like not having to wony about upgrades or maintaining patch levels on software application; also, there is the pay only for what you utilize. In other words, you pay only for the service you use. Yet, there is two underlying concerns to cloud computing, one being the loss of control over the organization data; this in itself has been and will continue to be a deterrent to companies contemplating cloud computing. Then we have the issue of security, both for data at rest (backups) and data that is being transmitted back and for across the network to the end user from the data center. The issue of security though it may sound major, it can be easily fixed by establishing secure communication between the data center and the end user by establishing secure socket layers (SSL) and/or virtual private network (VPN) connectivity and in many cases implement a public key infrastructure (PKI) utilizing certificates. As for the issue of loss of data/information control, that is a more difficult one to solve. The cloud solution to that is to implement a cloud IaaS where the organization has total control of the hardware and infrastructure the data is processed and stored on. However, if this is still of great concern to the organization the solution is to take the operation back to a physical location within the organization. In many cases the organization may need to accept the risk or revert to hosting their own private computing back at the company’s physical location.
