MIS Infrastructure
|
how to build, deploy, use, and share its data, processes, and MIS assets. like
Hardware, Software, Network, Client, Server, Procedures protects systems from failures and crashes |
|
|
Hardware
|
consists of the physical devices associated with a computer
|
|
|
Software
|
the set of instructions the hardware exectues to carry out specific tasks
|
|
|
3 Business benefits of a solid MIS Infrastructure
|
Supporting operations, Supporting change, Supporting the environment
|
|
|
Supporting operations
|
information MIS infrastructure identifies where and how important information, such as customer records, is maintained and secured.
|
|
|
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.
|
|
|
Backup
|
an exact copy of a systems information
|
|
|
Recovery
|
the ability to get a system up and running in the event of a system crash or failure
has 3 types fault tolerance,failover, failback |
|
|
Fail Tolerance
|
ability for a system to respond to unexpected failures or system crashes as the backup system immediately and automatically take over with no loss of service
super expensive |
|
|
Failover
|
a specific type of fault tolerance occurs when a redundant storage server offers an exact replica of the real-time data. If the primary server crashes, the users are automatically directed to the secondary server or backup server.
|
|
|
Failback
|
occurs when the primary machine recovers and resumes operations taking over from the secondary server
|
|
|
Hot Site
|
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
|
|
|
Business Continuity planning
|
Plan for how to recover by partially or completely interrupted critical functions, within a predetermined time, and emergency notification services
|
|
|
7 Characteristics of an agile MIS infrastructure
|
Accessibility, Availability, Maintainability, Portability, Reliability, Scalability, Usability
|
|
|
Accessibility
|
Refers to the varying levels that define what a user can access, view, or perform when operating a system
|
|
|
Administer access
|
Unrestricted access to the entire system.
can reset passwords, delete accounts, and shut down entire systems |
|
|
Availibility
|
Time frames when the system is operational
|
|
|
Unavailable
|
time frames when a system is not operating and cannot be used
|
|
|
Maintainability (flexibility)
|
How quickly a system can transform to support environmental changes
|
|
|
Portability
|
The ability of an application to operate on different devices or software platforms
|
|
|
Reliability (accuracy)
|
Ensures a system is functioning correctly and providing accurate information
|
|
|
Scalability
|
How well a system can scale up to increased demands
|
|
|
Performance
|
How quickly a system performs a process or transaction
|
|
|
Capacity Planning
|
Determines future 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
|
|
|
Moore's Law
|
Computer chip performance per dollar doubles every 18 months
Gordon Moore, co-founder of intel |
|
|
Sustainable, or "green" MIS
|
production, management, use, and disposal of technology in a way that minimizes damage to the environment
this is because the previous device is out of date |
|
|
Three Primary side effects of businesses' expanded use of technology
|
Increased electronic waste, increased energy consumption, increased carbon emissions
|
|
|
Increased Electronic waste
|
Ewaste, sustainable MIS disposal
|
|
|
Increased energy consumption
|
high increased in technology, greatly amplified energy consumption, the energy consumed by a computer=10% of carbon dioxide produced by an automobile
|
|
|
3 components of sustainable of MIS infrastructure
|
Grid Computing, Cloud Computing, Virtualized Computing
|
|
|
Grid Computing
|
collection of computers, often geographically dispersed, that are coordinated to solve a common problem
provides a potential competiitve advantage and additional cost savings. uses more than one computer |
|
|
Cloud Computing
|
the use of resources and applications hosted remotely on the Internet
doesnt need harddrive. it has its own saving mechanism, all you need is a device to access. |
|
|
Infrastructure as a service (Iaas)
|
service that delivers hardware networking capabilities, including the use of servers, networking, and storage over the cloud using a pay-per-use revenue model.
type of cloud computing |
|
|
dynamic scaling
|
means that the MIS infrastructure can be automatically scaled up or down based on needed requirements.
type of cloud computing |
|
|
software as a service
|
delivers applications over the clouds using a pay-per-use revenue model.
|
|
|
platform as a service
|
supports the deployment of entire systems including hardware, networking, and applications using a pay-per-use revenue model.
|
|
|
Virtualization
|
creates multiple "virtual"machines on a single computing device
is a fax machine, answering machine, and copy machine all in one physical machine |
|
|
Date Center
|
A facility used to house management information systems and associated components, such as telecommunications and storage systems
|
|
|
sustainable data center do what 3 things
|
reduces carbon emissions, reduces required floor space, gains geographic separation
|
|
|
Network
|
communications system created by linking two or more devices and establishing a standard methodology in which they can communicate
the greater importance in the infrastructure |
|
|
Client
|
computer designed to request info from a server
this would be someone uses a web browser |
|
|
server
|
computer dedicated to providing information in response to requests
the client being allowed access to the website |
|
|
Enterprise architect
|
person grounded in technology, fluent in business, and able to provide the important bridge between MIS and the business
|
|
|
Disaster recovery cost curve
|
the cost to the company of the unavailability of info and technology and the cost to the company of recovering from a disaster over time.
optimal time to recover is the crossing lines |
|
|

|
includes CDs, DVDs, Thumb drives, printer cartilidges, cell phones, iPodsS
|
|
|
