What is meant by defining IT infrastructure in terms of technology? in terms of service clusters?
o Define: shared tech resources for a business- including hardware, software, services
(consulting, education, training)
o Can be defined in terms of technology (physical devices, software app) or in terms of service clusters (service provided by the hardware and software)
o Examples of service clusters: computing, telecommunications, data mgmt, app software services, physical/facility services, IT standards/policies, IT educational services, IT R&D (research and development) services)
What is client/server architecture? Define the related terms: client, server, web server, application server, n-tiered / multitiered
o Client/server architecture is how clients and servers are linked together.
o Client is the user point of entry for the required function in a client/server computing. Normally a desktop computer, workstation, or laptop computer.
o Server is a computer specifically optimized to provide software and other resources to other computers over a network.
o Web server is software that manages requests for web pages on the computer where they are stored and that delivers the page to the user’s computer.
o Application server is software that handles all application operations between browser-based computers and a company’s back-end business applications or databases.
o N-tiered/multitiered is client/server network in which the work of the entire network is balanced over several different levels of servers.
Understand the following trends/technology impacting infrastructure (some will be review)
o Moore’s Law- Computing power double approximately every 18 months
o Law of Mass Digital Storage- Amount of digital info doubling every year & cost of storage falling at an exponential rate
o Metcalfe’s Law- Value of a network increases exponentially as the # of members increase
o Network Economies- model of strategic systems at the industry level based on the concept of a network where adding another participant entails zero marginal cost but can create much larger marginal gains.
o Declining Communication Costs / Internet- communication costs approach zero
o Standards / Network effects- Compatibility of products/ ability to communicate increases
shared tech resources for a business- including hardware, software, services.
largest category of computer, used for major business processing.
middle-range computer used in systems for university factories, or research laboratory.
technology that builds structures and processes based on the manipulation of individual atoms and molecules.
Describe the 7 infrastructure components listed, giving 2 examples of each
o Computer hardware platforms (client machines such as desktop PC’s, mobile computing devices such as PDA’s and laptops; and server machines)
o Operating system platforms (OSX, Linux, Microsoft, etc.)
o Enterprise software applications (SAP, Oracle, PeopleSoft, Microsoft, and BEA)
o Networking/telecommunications (Microsoft Windows Server, Linux, Novell, Cisco, Lucent, Nortel, MCI, AT&T, and Verizon)
o Consultants and System Integrators (IBM/KPMG, EDS, and Accenture)
o Data Management and Storage (IBM DB2, Oracle, SQL server, Sybase, MySQL, and EMC systems) (responsible for organizing and managing the firm’s data so that it can be efficiently accessed and used)
o Internet Platforms (Apache, Microsoft IIS, .NET, UNIX, Cisco, and Java)
Blade servers
entire computer that fits on a single, thin card (or blade) and that is plugged into a single chassis to save space and power and reduce complexity.
operating system for all types of computers that is machine independent and supports multiuser processing, multitasking, and networking. Used in high-end workstations and servers.
Microsoft family of operating systems for both network servers and client computers.
Storage Area Network (SAN)
a high-speed network dedicated to storage that connects different kinds of storage devices, such as tape libraries and disk arrays, so that they can be shared by multiple servers.
Web hosting service
company with large Web server computers used to maintain the web sites of fee-paying subscribers.
Legacy systems
a system that has been in existence for a long time and that continues to be used to avoid the high cost of replacing or redesigning it.
Grid computing
applying the resources of many computers in a network to a single problem.
On-demand computing
firms off-loading peak demand for computing power to remote, large-scale data processing centers, investing just enough to handle average processing loads and paying for only as much additional computing power as the market demands. Also called utility computing.
Autonomic computing
effort to develop systems that can manage themselves without user intervention.
Edge computing
method for distributing the computing load (or work) across many layers of the Internet computers to minimize response time.
Window on Management: How do Quantas and Ford use on-demand computing? How does it benefit each company?
o Quantas utilizes IBM to cover the infrastructure and systems that support the core application. IBM also provides service for information system procurement and security and a service desk for resolving issues with all the providers of its IT services. This has reduced costs for information technology and freed its new employees to pursue technology-modernization projects that may have higher value.
o Ford uses CDS to maintain an automated help desk service that is pay-as-you-go. This has reduced cost by 10%.
How does open-source software work?
o Free, can be modified by users, works derived from the original code are free, software can be redistributed by user without requiring additional licensing, not restricted to any operating system or hardware, currently based on either Linux or Unix.
What is Linux
o Free, open-source, related to Unix, created by Finnish programmer Linus Torvalds, August 1991, fastest growing client and server operating system, installed in nearly 3% of new shipments of PCs in 2004, works on all major hardware platforms from mainframes to server clients.
Read Window on Technology… In this case, what were the advantages and disadvantages of switching to Linux?
o Advantages: uses inexpensive desktop machines, stored on a central server networked to desktop client, open-source, no need to worry about licensing.
o Disadvantages: spend money and time training staff, software may not be compatible.
What is EAI software?
o Enables multiple systems to exchange data through a single software hub rather than building countless custom software interfaces to link each system.
What does Web Services refer to?
o Refer to a set of loosely coupled software components that exchange information with each other using standard Web communication standards and languages.
Describe the 3 external sources for software.
o Software packages from a commercial software vendor: prewritten commercially available set of software programs that eliminate the need for a firm to write its own software programs for certain functions, such as payroll processing or order handling.
o Software services from and application service provider: a business that delivers and manages applications and computer services from remote computer centers to multiple users using the Internet or a private network.
o Outsourcing: a firm contracts custom software development or maintenance of existing legacy programs to outside firms, frequently firms that operate offshore in low-wage areas of the world.
