Are students familiar with any of the trends in hardware or software platforms? Do they see the iPhone/iPad for instance as a device, a computing platform, or a just a telephone? They might be familiar with developments such as Facebookās Application platform, where developers can design games and activities for use within Facebook itself. Also recall that cloud computing has been mentioned in earlier chapters, so students should be able to point to that as a contemporary hardware platform trend.
The āservice platformā perspective refers to analyzing the actual services enabled by new technology tools. For example, a new PC might save an employee one hour per day in wait time for information, dramatically increasing his or her value to the firm.
The point of this slide is to illustrate the centrality of IT infrastructure and services to the achievement of firm success. Ultimately, what the firm delivers to customers, its quality, is a direct function of the power of its infrastructure. For instance, Amazon is routinely sited as the most popular online shopping site and receives high praise from customers for the quality of its service and speed of execution. There is a reason for this: Amazon has one of the worldās largest computing infrastructures numbering several hundred thousand processors to provide these services.
Students may be unfamiliar with the concept of mainframe computers. Explain the difference in size (much larger) and computing capacity (much smaller) from todayās computers to give them a sense of perspective regarding how far the computing industry has gone in 60 years. However, modern-day mainframes (IBM z-Series), are extremely powerful servers used for large Fortune 1000 enterprise networks and corporate Web sites. The mainframe is not dead in other words and still represents a large revenue stream for IBM.
Examples of the use of cloud computing are Google Apps, Googleās suite of software applications that rivals Microsoftās Office applications at a fraction of the cost, and Salesforce.comās CRM management software, delivered over the Internet. Most large Fortune 500 firms have some applications that run in the cloud. Most of these same corporations do not put their strategic or critical systems on the cloud just yet because of lingering concerns about reliability and security.
This slide shows the portion of Figure 5-2 that illustrates the first three eras of IT infrastructure evolution discussed in the previous slide. Explain so students understand that the yellow ring connecting the machines in the client-server graphic represents a local area network. Personal computers were stand-alone systems prior to the development of local area networks.
This slide shows the portion of Figure 5-2 that illustrates the last two eras of IT infrastructure evolution discussed in the previous slide. The enterprise Internet graphic represents several individual networks linked together into an enterprise-wide network. The cloud computing graph represents several types of technology that are capable of connecting to the Internet and accessing applications and services through a cloud. There is a Learning Track on the stages of IT infrastructure evolution.
Explain that the distribution of computing power across smaller, less expensive machines enabled by client/server computing is in part responsible for the drastic increase in computing power and applications throughout the firm. Prior to small, less expensive server computers, computing power had to purchased in large blocks at great expense. With client/server computing, you can grow your firmās inventory of computers gradually, over time, to meet current demand.
Variants of Mooreās Law include: the number of transistors on a chip doubles ever 18 months; computing power doubles every 18 months; and the price of computing falls by half every 18 months. Explain to students that even now, this trend is likely to continue, with transistors reaching the sizes of viruses, the smallest form of life.
At what point, if any, do students believe that the doubling trend of Mooreās Law might come to an end? Ask them to speculate and give reasons for their answers.
What do students think the implications of such drastically reduced costs of computer chips might be in the future? Explain the connection to concepts such as the digital divide and cloud computing.
Nanotechnology is used to create transistors of the tiny size previously mentioned. Can students describe any other applications of this type of technology (for example, medical)?
Explain the importance of the exponential growth in hard drive capacity, which is that the world is producing an increasing amount of digital information requiring storage each year as well. Fortunately, the cost of storing that information is decreasing at an even quicker rate. Explain that this figure displays the number of kilobytes of data that can be stored with one dollar. Point out that the Y axis is greatly compressed to display the doubling effect, and that if it werenāt, the increase from year to year would become increasingly enormous.
Ask students to explain the implications of Metcalfeās law to social networks, such as Facebook and MySpace. Do they agree that the more members are using the site, the value of being a member and the usefulness of the site grows? Do people make ānew friendsā on a social site or hang out with their existing friends mostly?
Are students aware of any friends or family that do not have Internet access? You might ask them to remember ālife before the Internetā, if possible, to underscore the magnitude of how far communication and computing has come over time. You might ask students to guess how fast (slow) were the telephone modems used by most Internet users in 1990s. Fifty-six kbps was the fastest telephone modem which is about 1/20th of a megabit per second. Most cable Internet to the home today is running at 2 to 4 mbps, forty to fifty times faster than telephone modems.
Emphasize to students how close the communication cost per kilobit has come to an infinitesimal number (nearly 0) since 1995. What implications does this have for the number of people using the Internet? You could once again relate this to the digital divide and emphasize that even now a significant portion of the world lacks access to the Internet and other services, though it has more to do with reasons of insufficient infrastructure than Internet communication costs. One implication: it costs no more to move a gigabyte from New York to San Francisco than it does to move the same amount of information from the top of a building to the basement. This means that data no longer needs to be located āclose byā the user.
The upcoming slides will go over each component in more detail.
Ask students to take a look at the example companies that appear under each heading. What companies appear repeatedly? How many items are unfamiliar?
Implementing new infrastructure requires significant changes in business processes and procedures, training and education, and software integration. This is a task that firms struggle to achieve on their own, which drives the need for these services. The MIS course provides students with an excellent background to be a business systems consultant. Most business consulting today involves developing business processes and supporting systems. You might visit a job/career site in class to review the kinds of jobs available to students with IS or MIS majors. One recent report (2010) found that MIS majors were the most satisfied group of college graduates because their education led directly to a job! The survey, which was conducted by PayScale.com and reported in the Wall Street Journal October 12, 2010, found 54% of MIS majors were very satisfied with their majors. Psychology majors at 26% were the least satisfied.
Business computing is increasingly moving from PCs and desktops to mobile devices, and managers are increasingly using these to coordinate work and communicate with employees. Students may think the smartphone they own is just a phone, or music player, but for businesses it is becoming an important management tool. Ask students for examples of how they are using smartphones in their business or work.
Both grid computing and virtualization allow organizations to optimize their use of resources in new ways. Grid computing allows corporations to take advantage of spare computing power in the form of networked virtual supercomputers. Virtualization allows companies also to take advantage of spare computing power by allowing a single resource to act as multiple resources.
Explain that on-demand or utility computing describes a payment structure in which use is dependent upon actual time or power used. Cloud computing refers to a platformānetworked access to remote services. Cloud computing allows organizations to avoid the expenses of maintaining their own hardware and software, relying on the cloud instead. Ask students if they have used Google Apps or other forms of cloud computing. Are there any other concerns they might have over transferring computing resources to a shared ācloudā? Have they read about Amazon Web Services going down and offline for short periods of time?
Data centers will use approximately 2% of all U.S. electrical power. Cutting power consumption in data centers has become both a serious business and environmental challenge. Ask students what forms of green computing they have noticed. Answers may range from more publicized local management of electronic equipment disposal and recycling to the use of solar chargers, and so on. Another driver in minimizing the power consumption of computer processors is the proliferation of handheld devices; to reduce heat in the devices as well as lengthen time between battery charges.
Emphasize that not only is there an environmental concern, but there is also the incentive to reduce costs by developing more efficient and environmentally friendly methods of powering systems. It is within the ability of almost any firm to take measures to āgo greenā with their computing. Virtualization is mentioned in the case as an effective way to reduce the total computing resources required to run applications.
Emphasize that the task Dollar wants to complete (interacting with other companiesā information systems) is represented here as a collection of individual services, in keeping with the SOA model. Dollar wants to be able to quickly and easily share data with other companiesāthe series of services provided above are combined to accomplish that task.
What are the ramifications of poor IT governance at a firm? For example, if a company does not clearly define what departments have the responsibility to make their own IT decisions, what could be the consequences? Some potential consequences are data mismanagement, poor communication, and slower response times to crises.
What types of companies should opt to rent as opposed to buy software? Possibly, companies with seasonal employees or semi-annual workloads. What differences between the two can students point to?
TCO is a way of quantifying some of the hidden costs of hardware. Ask students to make the connection between the TCO of handling software and hardware infrastructure internally as opposed to acquiring it from an outside vendor. Is this an additional incentive to outsource?
How important of an impact do competitorsā services and investments affect a firmās IT services and infrastructure? Is it wise to rely on those factors alone to determine what kind of services your firm provides? For instance, your competitors may not be the industryās best example of how to develop IT services. In fact, your entire industry might be technological laggards. In this case, it might be better to look at best practices in other industries which have a reputation for superior IT services and capabilities.
Ask students to explain how each item affects a firmās IT services and infrastructure. Do they feel that any one of the six is especially important (or unimportant)? You can also use this diagram as a framework for understanding why some firms fail to develop a workable, powerful IT infrastructure.
