Chapter 5 Infrastructures and Sustainable Tech Flashcards
information mis infrastructure
supports operations; backup, recovery, disaster recovery, business continuity
agile mis infrastructure
supports change; accessibility, maintainability, reliability
sustainable mis infrastructure
supports sustainability; grid computing, cloud computing, virtualization
backup
an exact copy of a system’s information
recovery
the ability to get a system up and running int eh event of a crash or failure
fault tolerance
the ability for a system to respond to unexpected failures or crashes as the backup system takes over.
enterprise architect
the person fluent in business and able to provide the bridge between mis and business
disaster recovery plan
process for recovering information or a system in the event of a disaster
cold site
separate facility not equipt for work, but a place that ees can move to after a disaster
hot site
separate fully equipt facility ready to start operations in the event of a disaster
warm site
separate facility with computer equipment that requires installation
accessibility
varying levels of what a user can access
high availability
when a system is continually operational at all times
maintainability
how quickly a system can transform to support environmental changes
scalability
how well a system can scale up or adapt to the increased demands of growth
usability
the degree to which a system is easy to learn and efficient to use
vulnerability
system weakness that can be exploited by a threat (passwords)
reliability
ensures a system is functioning correctly and providing accurate information
iaas
infrastructure as a service; delivery of hardware capability as a service
grid computing
collection of computers often geographically spread out that are coordinated to solve a certain problem
moores law
computer chip performance per dollar doubles every 18 months
paas
platform as a service; supporting deployment of systems including hardware and networking using pay per use models
saas
security as a service; antivirus software delivered over the internet serving virus updates
virtualization
creates many virtual machines on a single computing device
network virtualization
combines networks by splitting the available bandwidth into independent channels that can be assigned in real time to a device
server virtualization
combines the resources like servers and processors from the application
storage virtualization
combines multiple network storage devices to they appear as one storage device
system virtualization
ability to present the resources of 1 computers a collection of separate computers, each with its own network interfaces and storage
