Ch. 5 - Infrastructures: Sustainable Technology Flashcards
creates multiple ‘virtual’ machines on a single computing device
Virtualization
combines networks by splitting available bandwidth into independent channels that are assigned in real time to a specific device
Network Virtualization
combines the physical resources, such as servers, processors, and operating systems, from the applications. Most common form, think of this when you hear virtualization
Server Virtualization
combines multiple network storage devices so they appear to be a single storage device
Storage Virtualization
the ability to present the resources of a single computer as if it’s a collection of separate computers, each w/ its own virtual CPU, network interfaces, storage, and operating system
System Virtualization
delivers applications over the cloud using a pay-per-use revenue model
Software as a Service (SaaS)
supports the deployment of entire systems, including hardware, networking, and applications, using a pay-per-use revenue model
Platform as a Service (PaaS)
delivers hardware networking capabilities, including the use of servers, networking, and storage, over the cloud using a pay-per-use revenue model
Infrastructure as a Service (IaaS)
varying levels allow system users to access, view, or perform operational functions
Accessibility
the system is operational during different time frames
Availability
the system quickly transforms to support environmental changes
Maintainability
the system is available to operate on different devices or software platforms
Portability
the system functions correctly and provides accurate info
Reliability
the system can scale up or adapt to the increased demands of growth
Scalability
the system is easy to learn, efficient, and satisfying to use
Usability
