week 10 Flashcards
consumerzation of IT and BYOD (bring your own device)
- forces businesses and IT departmenrs to rethink how IT equipment and services are aqcuired and manged
quatum computing
Uses quantum physics to represent and operate on data
- increases computing speed
visualzation
- Allows single physical resource to act as multiple resources
- Enables multiple physical resources ( such as storage devices) to appear as a single logical resources ( such as in software defined storage (SDS))
- Reduces hardware and power expenditures
- Facilitates hardware centralization
cloud computing
- Gives access to on-demand computing services (hardware and software)
- Virtualized resources provided over a network (the internet)
-Public or private
- Allows companies to minimize IT investments
drawbacks
- concerns of security realibilty
cloud computing infastructures
- computing power
- processor (CPU- centeral processing unit)
- GPU (graphics processing unit)
(renders graphics and images by performing rapid mathematical calculations) - HPC (high performance computers)
(the ability to process data and perform complex calcuations at high speeds
- storage
- network
what are the 5 essiential charetistics of cloud computing
- on demand self service
- ubiquitous network access
- location-independent resource pooling
- rapid elasticity
- measured service
on demand self service
consumers can obtain computing capabilites such as server time or network storafe as needed automatically on their own
ubiquitouis network access
cloud resoruces can be accessed using stnadrd network and internet devices including mobile platfroms
location independent resource pooling
computing resources are poled to serve multiple users with different virtual resources dynamically assigned accordinf to user demand the user generally does not know the computing resources are located
rapid elasity
computing resources can be rapidly proviosend, increased, or decreased to meet chaning user demand.
measured service
charges for cloud resources are based on amount of resoruces actually used
3 types of cloud computing services
- software as service (Saas)
- platform as a services (PaaS)
- infastructure a a service (Laas)
software as service (SaaS)
- software hosted by the vendor
- subscription services
platform as a service
Infrastructure and programming tools to develop applications
infastructure as a service
Processing, storage, networking and other computing resources
edge computing
Servers at the edge of the network near the source of the data
Reduced latency ( data transfer delay) and network traffic
Edge server
Edge devices
green computing (Green IT)
Practices and technologies for manufacturing disposing of computing and networking hardware
Reducing power consumptions a high priority
Green data centers
high performance
More efficient and power-saving processors
multiple processors
-an integrated circuit to which two or more processor views have been attached
for enhanced performance reduced power consumption and more efficient
simultaneous processing of multiple tasks
open source software
Free and can be modified by users
Examples: linux apache web server mozilla firefox browsers
software for the web
Java: tuns on any device programming language for the web can use it to run
Web browsers: an easy-to-use software tool with a graphical user (GUI) for displaying web pages and for accessing the web
HTML and HTM5: a page description language
software for the web: python
Open source programming language
Used in data science
Programming experience
Machine learning
General purpose, object oriented language
web service
a method of communication between two electronic devices over sa network
XML: extensible markup language: supports information exchange between computer system such as websites databases and third party applications
