MIS Chapter 5

Emergency Notification Service
An infrastructure built for notifying people in the event of an emergency. Example: Radio stations
It can be deployed through the firm’s own infrastructure, supplied by an outside service provider on company premisis or hosted remotely by an outside service provider.
Technology Failure

Incidents
Unplanned interruption of a service
Technology Recovery Strategies
Focuses specifically on prioritizing the order for restoring hardware, software and the data across the organization that best meets recovery requirements.
Hardware
Servers, computers and wireless devices
Software
Applications such as email, payroll and instant messaging
Data Center
Climate control, power supply and security
Networking
Wireless, LAN, fiber and cable
Accessibility
Refers to the varying levels that define what a user can access, view or perform when operating a system
Administrator Access or Unrestricted Access

Web Assessibility Initiative (WAI)
Brings together people from industry, disability organizations, gov’t and research labs around the world to dev. guidelines and resources to help make the web accessible to people with disabilities. It allows people to access the full potential of the web.
Community Cloud
Serves a specific community with common business models, security requirements, and compliance considerations. Community clouds are emerging in highly regulated industries such as financial services and pharmaceutical companies.
Data Center
A facility used to house management info systems and asso. components such as telecommunications and storage systems. Sometimes referred to as “server farms.” They consume power and require cooling and floor space while working to support business growth w/o disrupting normal business operations and the quality of service.

Infrastructure as a Service (IAAS)
Delivers hardware networking capabilities, including the use of servers, networking and storage over the cloud using pay-per-view revenue model.
Utility Computing
Offers pay-per-view use revenue model similar to a metered service.
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.
Disaster Recovery Cost Curve
Charts 1) Costs to the company of the unavailability of info and technology 2) The costs to the company of recovery from a disaster over time.
Carbon Emissions
Carbon dioxide and carbon monoxide produced by business processes and systems that are not reduced.
Business Impact Analysis
Identifies all critical business functions and the effect that a specific disaster may have upon them.
Cloud Computing
A model for enabling ubiguitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction. Connects people when internet is not available.
Agile MIS Infrastructure Characteristics
Accessibility – varying levels allow system users to access, view or perform operational functions.
Availability
System is operational during different time frames
Maintainability
The system quickly transforms to support environmental changes.
Portability
The system is available to operate on different devices or software platforms. Example: Apple Itunes
Reliability
The system functions correctly and provides accurate info.
Scalability
The system can “scale up” or adapt to the increased demands of growth.
Usability
The system is easy to learn and efficient and satisfying to use.
Recovery
The ability to get a system up and running in the event of a system crash or failure that includes restoring the info back-up.
Technology Recovery Strategies
Focuses specifically on prioritizing the order for restoring hardware, software and data across the organization that best meets business recovery requirements.
Ways Data Centers can be more Sustainable
1) Carbon emissions 2) Reduce energy consumption 3) Floor space 4) Stores greater amounts of info in less space 5) Geographic location 6) Resources are inexpensive, clean and available
Disaster Recovery Plan
Detailed process for recovering info or a system in the event of a catastrophic disaster.
Business Continuity Planning
1) Disaster recovery plan 2) Technology recovery strategies 3) Business impact analysis 4) Emergency notification services
Single Tenancy
Each customer or tenant must purchase and maintain and individual system.
Multi-Tenancy
Helps reduce operational costs associated with implementing large systems as costs are dispersed across many tenants.
Fault Tolerance
The ability for a system to respond to unexpected failures or system crashes as the back-up system immediately and automatically takes over with no loss of service
Software as a Service
Delivers applications over the cloud using a pay-per-use revenue model.
Server
Computer dedicated to providing info in response to requests.
Cloud Fabric
Software that makes possible the benefits of cloud computing, such as multi-tenancy.
Three Primary Elements of MIS Infrasture
1) Back up and recovery plan 2) Disaster recovery plan 3) Business continuity plan
Dynamic Scaling
MIS infrastructure can be automatically scaled up or down based on needed requirements.
Capacity
Reps the max throughout a system
Example: Capacity of a hard drive
Enterprise Architect
Person grounded in technology, fluent in business and able to provide the important bridge between MIS and the business.
On demand Service
Users can increase storage and processing power as needed
Broad Network Access
All devices can access data and applications
Rapid Elasticity
Storage, network bandwidth and computing capacity that can be increased or decreased
Measured Service
Clients can monitor and measure transactions and use of resources
Emergency
Sudden, Unexpected event requiring immediate action due to potential health and safety, the environment or property.
Client
A computer designed to request info from a server.
Virtualization
Creates multiple virtual machines on a single computing device Example: computer printer
3 Processes Driving Sustainable MIS Infrastructures
1) Increased electronic waste 2) Increased energy consumption 3) Increased carbon emissions
Ewaste
Discarded, obsolete or broken electronic devices
Smart Grid
Delivers electricity using 2-way digital technology. It is meant to solve the problem of the world’s outdated electrical grid, making it more efficient and reliable by adding the ability to remotely monitor, analyze and control the transmission of power.
Failover
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 or back-up server.
Capacity Planning
Determines future environmental infrastructure requirements to ensure high quality system performance.
