1.2. Cloud computing Flashcards
cloud computing
- use of
> resources/software
> as services
> Internet/online - remotely
> shared
> subscription fee
> scalable
how are resources shared in cloud computing
like how processing power shared between users
what does ‘in the cloud’ mean
data use on the Internet
advantages of cloud computing affects limitations on access to data and processing power
- not limited to
> location
> device (any OS)
> size > scalable - limited to
> Internet connection > fast & reliable
> fee
examples of cloud computing
- online storage
> file syncing
> backup - media repositories
- cloud applications
examples of online storage - file syncing
Dropbox
iCloud/OneDrive/Google Drive
SugarSync
CX
what does online storage - file syncing do?
stores files on Internet
like virtual hard drive
access, add, delete
how does online storage - file syncing work?
- indicate files on comp synced to Internet
> web interface on browser
> app
+ integrates OS file system
+ automatically synced folder
= security risk on public tech
what files would you want to store in online storage - file syncing
- multi-device access
- share
- copy (like backup, not as good)
what did online storage - file syncing replace?
- e-mailing files
- USB
charges for online storage - file syncing
- usually free version
> limited storage - monthly subscription
> more storage
> charged/GB
what is online/cloud storage - backup?
backup data
access in emergency
how do cloud backup services work?
- automatic schedule
1. backup drive/specified folders
2. incremental duplication of changed files
how does cloud backup differ to cloud syncing?
more data
less data traffic
what does cloud backup enable access to?
- history of file versions
- files deleted from computer
special feature of online backup services
most encrypt data > only you decrypt/access > increased security
how is cloud backup better than cloud syncing in terms of backup power
- incremental
- secure
examples of online backup programs
Carbonite
Acronis
CrashPlan
charge of online backup
sub fee / user or computer
what is a (media) repository?
safe online storage location
- buy cloud access to media

Office 365 - sub fee
what are consumer cloud applications
- anyone
< most cloud business/service - high processing power
examples of consumer cloud applications
123D Catch (Autodesk)
Microsoft Photosynth
why are consumer cloud applications used?
online server processing higher than local device
what is 123D Catch
photo of object > digital 3D object
> use in 3D software
what is photosynth
many diff photos (angle, zoom) of locaysh stitched
> pan-able, zoomable mega-panorama
> 3D view
charges of 123D Catch and Photosynth and how run and why better

Cloud-based apps
Downloadable, locally installed apps
Integrated products
how do cloud-based apps reflect when they are SaaS
