FSU Franks Terms in this set (99)MIS infrastructure includes the plans for how a firm will build, deploy, use, and share its data, processes, and MIS assets a solid MIS infrastructure can
reduce costs, improve productivity, optimize business operations, generate growth, and increase profitability. Hardware consists of the physical devices associated with a computer system software the set of instructions the hardware executes to carry out specific tasks how are most hardware and software run today? via a network network A communications system created by linking two or more devices and establishing a standard methodology in which they can communicate client A computer that requests data stored on a server. server a computer dedicated to providing information in response to requests is an MIS infrastructure dynamic or static? dynamic; continually changes as the business needs enterprise architect a person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business; help change and update MIS infrastructure as needed three areas enterprise architects focus on when maintaining a firms MIS infrastructure 1. supporting operations Supporting Operations (information MIS infrastructure)identifies where and how important info is maintained and stored supporting change (Agile MIS Infrastructure) includes the hardware, software, and telecommunications equipment that, when combined, provides the underlying foundation to support the organization's goals. supporting the environment (Sustainable MIS infrastructure) identifies ways that a company can grow in terms of computing resources while simultaneously becoming less dependent on hardware and energy consumption MIS infrastructures figure Areas of Support Provided by Information Infrastructure backup An exact copy of a system's information recovery the ability to get a system up and running in the event of a system crash or failure that includes restoring the information backup fault tolerance the ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service failover a specific type of fault tolerance, occurs when a redundant storage server offers an exact replica of the real-time data, and if the primary server crashes, the users are automatically directed to the secondary server or backup server (high-speed and high-cost) failback occurs when the primary machine recovers and resumes operations, taking over from the secondary server low-speed and low-cost backup options DVDS or thumb drives effects of a disaster on companies and businesses - disrupting communications disaster recovery plan A detailed process for recovering information or an IT system in the event of a catastrophic disaster such as a fire or flood Sites to support disaster recovery hot site is a separate and fully equipped facility where the company can move immediately after a disaster and resume business cold site A separate facility that does not have any computer equipment, but is a place where employees can move after a disaster warm site A separate facility with computer equipment that requires installation and configuration disaster recovery cost curve charts (1) the cost to the company of the unavailability of information and technology and (2) the cost to the company of recovering from a disaster over time emergency a sudden, unexpected event requiring immediate action due to potential threat to health and safety, the environment, or property Emergency preparedness ensures a company is ready to respond to an emergency in an organized, timely, and effective manner Business Continuity Planning (BCP) details how a company recovers and restores critical business operations and systems after a disaster or extended disruption BCP includes such factors as identifying critical systems, business processes, departments, and the maximum amount of time the business can continue to operate without functioning systems business impact analysis Identifies all critical business functions and the effect that a specific disaster may have upon them emergency notification service an infrastructure built for notifying people in the event of an emergency
technology failure occurs when the ability of a company to operate is impaired because of a hardware, software, or data outage incidents unplanned interruption of a service incident record contains all of the details of an incident incident management the process responsible for managing how incidents are identified and corrected technology recovery strategies focus specifically on prioritizing the order for restoring hardware, software, and data across the organization that best meets business recovery requirements Key Areas of Technology Recovery Strategies Agile MIS Infrastructure Accessibility Refers to the varying levels that define what a user can access, view, or perform when operating a system administrator access unrestricted access to the entire system web accessibility Allows people with disabilities to use the Web Web Accessibility Initiative (WAI) brings together people from industry, disability organizations, government, and research labs from around the world to develop guidelines and resources to help make the web accessible to people with disabilities, including auditory, cognitive, neurological, physical, speech, and visual disabilities availability refers to the time frames when the system is operational unavailable Time frames when a system is not operating and cannot be used high availability occurs when a system is continuously operational at all times maintainability (flexibility) refers to how quickly a system can transform to support environmental / business/ company changes portability refers to the ability of an application to operate on different devices or software platforms, such as different operating systems reliability (accuracy) ensures a system is functioning correctly and providing accurate information vulnerability a system weakness, such as a password that is never changed or a system left on while an employee goes to lunch, that can be exploited by a threat Scalability How well a system can scale up, or adapt to the increased demands of growth performance measures how quickly a system performs a certain process or transaction capacity represents the maximum throughput a system can deliver capacity planning determines future environmental infrastructure requirements to ensure high-quality system performance Usability The degree to which a system is easy to learn and efficient and satisfying to use Servicability How quickly a third-party can change a system to ensure it meets user needs and the terms of any contracts, including agreed levels of reliability, maintainability, or availability Moore's Law Refers to the computer chip performance per dollar doubles every 18 months (was originally 2 years) Sustainable, or "green," MIS Describes the production, management, use, and disposal of technology in a way that minimizes damage to the environment
Corporate Social Responsibility Companies' acknowledged responsibility to society clean computing a subset of sustainable MIS, refers to the environmentally responsible use, manufacture, and disposal of technology products and computer equipment green personal computer (green PC) built using environment-friendly materials and designed to save energy Ewaste refers to discarded, obsolete, or broken electronic devices upcycle reuses or refurbishes ewaste and creates a new product Sustainable MIS disposal Refers to the safe disposal of MIS assets at the end of their life cycle Three Pressures Driving Sustainable MIS Infrastructures energy consumption the amount of energy consumed by business processes and systems carbon emissions Carbon dioxide and carbon monoxide produced by business processes and systems Sustainable MIS Infrastructure components grid computing A collection of computers, often geographically dispersed, that are coordinated to solve a common problem (distributed to many machines, using about 25% or processing power; good for scalability) smart grid delivers electricity using two-way digital technology (more efficient and reliable than the outdated electrical grid) Virtualization Creates multiple "virtual" machines on a single computing device benefits of virtualization - higher level of performance
Storage Virtualization combines multiple network storage devices so they appear to be a single storage device network virtualization combines networks by splitting the available bandwidth into independent channels that can be assigned in real time to a specific device server virtualization combines the physical resources, such as servers, processors, and operating systems, from the applications (most common) data centers A facility used to house management information systems and associated components, such as telecommunications and storage systems ways for data centers to become sustainable cloud computing stores, manages, and processes data and applications over the internet rather than on a personal computer or server cloud computing advantages Multi-tenancy in the cloud means that a single instance of a system serves multiple customers (aka tenants) reduces operational costs Single-tenancy each customer or tenant must purchase and maintain an individual system cloud fabric The software that makes possible the benefits of cloud computing, such as multi-tenancy cloud fabric controller an individual who monitors and provisions cloud resources, similar to a server administrator at an individual company characteristics of cloud computing utility computing offers a pay-per-use revenue model similar to a metered service such as gas or electricity Infrastructure as a Service (IaaS) delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model dynamic scaling Means that the MIS infrastructure can be automatically scaled up or down based on needed requirements. disaster recovery as a service (DRaaS) offers backup services that use cloud resources to protect applications and data from disruption caused by disaster Cloud Service Delivery Models Software as a Service (SaaS) delivers applications over the cloud using a pay-per-use revenue model Platform as a Service (PaaS) supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model Cloud Computing environments -private cloud Public Cloud promotes massive, global, and industrywide applications offered to the general public Private Cloud serves only one customer or organization and can be located on the customer's premises or off the customer's premises community cloud serves a specific community with common business models, security requirements, and compliance considerations hybrid cloud includes two or more private, public, or community clouds, but each cloud remains separate and is only linked by technology that enables data and application portability Sets found in the same folderISM3003 Ch 7106 terms juliapellasce2 ISM3003 Exam 1215 terms juliapellasce2 ISM3003 Ch 4113 terms juliapellasce2 ISM3003 Ch 682 terms juliapellasce2 Other sets by this creatorMAN4720 Final Exam Part 284 terms juliapellasce2 MAN4320 Staffing Exam 237 terms juliapellasce2 MAN4330 Compensation Exam 357 terms juliapellasce2 MAN4310 Exam 291 terms juliapellasce2 Verified questionsCOMPUTER SCIENCE What color is color_rgb(0,255,255)? a) yellow b) cyan c) magenta d) orange Verified answer

What refers to the applications services and data stored over the Internet?Cloud Computing. "The cloud" refers to applications, services, and data storage on the Internet. These service providers rely on giant server farms and massive storage devices that are connected via Internet protocols. Cloud computing is the use of these services by individuals and organizations.
What delivers applications over the cloud using a pay per use revenue model?In the software as a service (SaaS) model, users gain access to application software and databases. Cloud providers manage the infrastructure and platforms that run the applications. SaaS is sometimes referred to as "on-demand software" and is usually priced on a pay-per-use basis or using a subscription fee.
What combines networks by splitting the available bandwidth into independent channels that can be assigned in real time to a specific device?Network virtualization is a method of combining the available resources in a network by splitting up the available bandwidth into channels, each of which is independent from the others and can be assigned -- or reassigned -- to a particular server or device in real time.
