...ISYS104 Tutorial – week 6 Review Questions 1. What is IT infrastructure and what are its components? Define IT infrastructure from both a technology and a services perspective. • Technical perspective is defined as the shared technology resources that provide the platform for the firm’s specific information system applications. It consists of a set of physical devices and software applications that are required to operate the entire enterprise. • Service perspective is defined as providing the foundation for serving customers, working with vendors, and managing internal firm business processes. In this sense, IT infrastructure focuses on the services provided by all the hardware and software. IT infrastructure is a set of firm-wide services budgeted by management and comprising both human and technical capabilities. List and describe the components of IT infrastructure that firms need to manage. Students may wish to use Figure 5-10 to answer the question.

...and each specializes in one or more cloud services. These services are Software as a Service (SaaS), Platform as a Service (PaaS), and Infrastructure as a Service (IaaS). The first cloud service, Software as a Service (SaaS), is arguably the most well-known. SaaS allows the use of an application or app by countless users in any location in the world. The benefit to this technology is that when a user needs access to a particular software program they do not have to be at any one location (Microsoft, 2012). Microsoft 365 is an example of SaaS and is subscription based. Users login to the program from any device with an internet connect and are able to save documents and files on the cloud network rather than or along with their device’s hard drive. Another type of SaaS is Symantec backup services. Symantec offers complete back up services so that other businesses do not need to invest in expense hardware. This is vital to small businesses who cannot afford the expensive infrastructure. Symantec’s service backs up on a set schedule ensuring consistency (Symantec, 2013). SaaS has numerous benefits, one of the most important being lower expenses. SaaS allows businesses to save files as well as run programs on a host’s server. This lowers expenses for businesses as they do not have to invest as much in costly hardware. They also are able to reduce energy consumption as they are not running their own hardware and cooling systems. Another financial benefit is companies utilizing...

...Managing Information System Infrastructure Issues Iris Goldston CMGT 445 Charlie Neuman May 4, 2013 Abstract Managing an Information System Infrastructure is a difficult task that involves many facets and therefore many possible issues. An extreme advance in information technology is enabling business to have many opportunities. The advancement has brought about many challenges from obsolete hardware and software issues such as when to upgrade and how to ever increasing need for storage space. Energy consumption to support the new technology is expensive and therefore affects the bottom line of any business. The challenge to consume less energy and save money is an important concern, especially when going green builds consumer loyalty. As the need to keep up with new technology to keep or gain a competitive advantage, companies have to decide whether to build, rent, or simply maintain a facility to support its hardware. And finally, as with any business supply and demand fluctuates and with this comes the question of how to scale the power uses of an IS infrastructure. Configuration and Preventative Maintenance Configuring an Information System (IS) infrastructure involves hardware, software, communications and collaborations networks, database, human resources, and security. Preventative maintenance should include flexibility, strategic, and tactical planning. The hardware is all monitors, servers, mainframes, keyboards, desktops, and in some cases mobile...

...Chapter 5 IT Infrastructure and Emerging Technologies As information becomes a valuable resource of a digital firm, the infrastructure used to care for it takes on added importance. We’ll examine all of the components that comprise today’s and tomorrow’s IT infrastructure and how best to manage it. 5.1 IT Infrastructure When you mention the phrase “information technology infrastructure,” most people immediately think of just hardware and software. However, there is more to it than just those two. In fact, the most important and often most-ignored component is that of services. Integrating all three components forces a business to think in terms of the value of the whole and not just the parts. Including all three components in any discussion of IT infrastructure truly fits the cliché that the whole is greater than the sum of its parts. Defining IT Infrastructure If you define a firm’s IT infrastructure in terms of technology you limit the discussion to the hardware and software components. By broadening the definition to that of service-based, you are then bringing into the discussion the services generated by the first two components. Also, you are including the persware element that we discussed in Chapter 1. As technology advances the types of hardware and software available, it becomes more critical for the firm to focus on the services that a firm can provide to its customers, suppliers, employees, and business partners. To round out the list of IT infrastructure components...

...model(PaaS), Software- as- a- service model (SaaS), Infrastructure-as-a-Service model (IaaS). IaaS is a third party service model which makes use of hardware, software, servers, storage and other infrastructure modules on behalf of the users on the network. IaaS provides the connected users with a web-based service to create, obliviate and administer storage and systems. Security remains a big issue of concern especially because the other service models run on top of the infrastructure layer. PaaS provides hardware and software equipments required for the development of applications to it’s users over the worldwide web. PaaS provides access to Application Program Interfaces( APIs) and other equipments necessary or developing applications without having to install the developing environment. SaaS gives the connected users access to software/ services available on the cloud. SaaS requires the Web Browser to to access the applications hosted by the cloud. Although this concept provides ease in terms of cost- cutting and low management requirement of systems, the data remains vulnerable to unauthorized interference and misuse. This poses a threat to data security which becomes a great concern on multiple levels and dimensions. This paper aims at highlighting each and every threat to data security in general and the possible defense mechanisms/ solutions employed against the same.

..."computing", the meaning gets bigger and fuzzier. Some analysts and vendors define cloud computing narrowly as an updated version of utility computing: basically virtual servers available over the Internet. Others go very broad, arguing anything you consume outside the firewall is "in the cloud", including conventional outsourcing. Cloud computing comes into focus only when you think about what we always need: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends ICT's existing capabilities. Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging. ______________________________________Cloud computing - The Concept Cloud computing is Internet ("cloud") based development and use of computer technology ("computing"). It is a style of computing in which dynamically scalable and often virtualized...

...virtual (rather than actual) version of something, such as an operating system, a server, a storage device or network resources. In layman's term, virtualization allows you to run an independent operating system within an existing operating system using the existing hardware resources. So if you want to learn another operating system like Linux, you can use virtualization to run Linux on top of the existing operating system. Virtualization is the abstraction of IT resources, separating their physical instance and boundaries from their function. Virtualization has brought important innovation to IT Virtualization concept was first developed by IBM in the 1960s to fully utilize mainframe hardware by logically partitioning them into virtual machines. These partitions will allow mainframe computers to perform multiple tasks and applications at the same time.. During the 1980s and 1990s, desktop computing and x86 servers become available and so the virtualization technology was discarded eventually. Client-server applications and the emergence of Windows and Linux made server computing significantly inexpensive. However, new challenges has surfaced which includes high maintenance and management cost, high infrastructure cost, and insufficient failure and disaster protection that lead to the invention of virtualization for x86 platform. VMWare invented virtualization for the x86 architecture in the 1990s to address the above mentioned problems. In 1999, VMW are introduced a virtualization...

...Institute – Miami 5/29/2014 IDI cannot continue operating with a neglected IT infrastructure. A plan needs to be prepared to identify every issue with the IT infrastructure. Such plan should describe actions to eliminate or mitigate the risks, and provide a framework within which the improvement, development and delivery of information technology could be increasingly responsive, stable, and secure in the coming years. Some of the upgrades included on that plan are the following: •Network infrastructure should be upgraded to Gigabit Ethernet, considerably increasing network speed •Port speed needs to be increased from 10 Mbps to 100 Mbps •IDI Internet bandwidth should double immediately and significantly increased annually from that point forward •Deteriorating network infrastructure components have to be identified, replaced, and upgraded, and network reliability improved through the implementation of greater redundancy •Digital modems should replace the analog modems, improving reliability and connection speed •Wireless network standards need to be developed and implemented, and wireless access needs to be provided to several other locations •A new central directory needs to be created and developed as the authoritative source for identity information and authentication •A state-of-the-art backup system will be implemented for centralized backup of enterprise systems Upgrading IDI’s software is more than just an economic business decision.
