System Virtualization
the ability to present the resources of a single computer as if it is a collection of separate computers ("virtual machines"), each with its own virtual CPUs, network interfaces, storage, and operating system.
Clean computing
the environmentally responsible use, manufacture, and disposal of technology products and computer equipment -production of environmental waste
Failback
when the primary machine recovers and resumes operations, taking over from the secondary server
Energy Consumption
-The amount of energy consumed by business processes and systems -Huge increase in tech have greatly amplified energy consumption -The energy consumed by a computer is estimated to produce as much as 10% of the amount of carbon dioxide produced by cars
Smart Grid
-delivers electricity using two-way digital technology -it is meant to solve the problem of the world's outdated electrical grid, making it more efficient and reliable by adding the ability to remotely monitor, analyze, and control the transmission of power
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 -mix of public or private community -Example: private cloud for company and public cloud for customers, suppliers, and partners
Increased Carbon Emissions
-major human-generated greenhouse gases, such as carbon emissions from energy use, are very likely responsible for the increases in climatic temperature over the past half a century
Performance
-measures how quickly a system performs a process or transaction -a key component of scalability -SPEED
Public Cloud
-promotes massive, global, and industrywide applications offered to the general public -customers are never required to provision, manage, upgrade, or replace hardware or software -multi-tenancy, off premise, several organizations -Example: amazon
Community Cloud
-serves a specific community with common business models, security requirements, and compliance considerations -multi-tenancy, off premise, several organizations -Example: private hospital
Private Cloud
-serves only one customer or organization and can be located on the customer's premises or off the customer's premises -single tenancy, on premise, one organization -Example: bank

Emergency Preparedness
Ensures a company is ready to respond to an emergency in an organized, timely, and effective manner
The components of sustainable MIS infrastructure inclue
Grid Computing, Virtualized Computing, and Cloud Computing
Multi-tenancy
Multi-tenancy in the cloud means that a single instance of a system serves multiple customers -helps to reduce operational costs associated with implementing large systems as the costs are dispersed across many tenants -Customers share pooled computing resources
Technology Failure
Occurs when the ability of a company to operate in impaired because of a hardware, software, or data outage
Sustainable MIS Disposal
Refers to the safe disposal of MIS assets at the end of their life cycle -ensures they don't end up in land-fills
Accessibility
Refers to the varying levels that define what a user can access, view, or perform when operating a system
Increased Economic Waste
Side Effect of Businesses' Expanded Use of Tech
Usability
The degree to which a system is easy to learn and efficient and satisfying to use (how easy the first iPod was to use)
Incident Management
The process responsible for managing how incidents are identifies and corrected
Cloud Fabric
The software that makes possible the benefits of cloud computing, such as multi-tenancy
Unavailable
Time frames when a system is not operating and cannot be used
Availability
Time frames when the system is operational
Incident
Unplanned interruption of a service
Administrator Access
Unrestricted access to the entire system
On Demand Self Service
Users can increase storage and processing power as needed
Fault Tolerance
a general concept that a system has the ability to respond to unexpected failures or system crashes as the backup system immediately and automatically takes over with no loss of service, very expensive and rare to use
Failover
a specific type of fault tolerance that 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
Technology Recovery Strategies
focus on specifically prioritizing the order for restoring hardware, software, and data across the organization that best meets business recovery requirements
Business Impact Analysis
identifies all critical business functions and the effect that a specific disaster may have upon them primarily used to ensure a company has made the right decisions about the order of recovery priorities and strategies
Emergency Notification Service

Capacity
maximum throughput a system can deliver, a hard drive represents its size or volume
The Cloud
offers a company higher availability, greater reliability, and improved accessibility—all with affordable high-speed access
Virtualization
one of the easiest and quickest ways to achieve a sustainable MIS infrastructure because it reduces power consumption and requires less equipment that needs to be manufactured, maintained, and later disposed of safely
Grid Computing
-A collection of computers, often geographically dispersed, that are coordinated to solve a common problem -a problem is broken into pieces and distributed to many machines, allowing faster processing than could occur with a single system
Capacity Planning
-Determines future environmental infrastructure requirements to ensure high-quality system performance -If a company with 100 workers merges with another company and suddenly there are 400 people using the system, performance time could suffer
Reliability
-Ensures a system is functioning correctly and providing accurate information -Accuracy -Wiki
Maintainability
-How quickly a system can transform to support environmental changes -Must watch today's business and tomorrow's when designing and building systems -Systems must be flexible (different currencies and languages)
Moore's Law
-Refers to the computer chip performance per dollar doubles every 18 months -observed in 1965 that continued advances in technological innovation made it possible to reduce the size of a computer chip (the brains of a computer, or even a cell phone now) while doubling its capacity every two years
Business Continuity Plan
A plan for how an organization will recover and restore partially or completely interrupted critical functions within a predetermined time after a disaster or extended disruption
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(natural disasters and rats chewing on cords, which is the most common)
Data Center
A facility used to house management information systems and associated components, such as telecommunications and storage systems -consume power and require cooling and floor space while working to support business growth without disrupting normal business operations and the quality of service
Serviceability
