2. History of Data Storage
• Computers have stored data using a range of different technologies
over the years
• Originally, computer data was stored using
punch cards which represented computer data
• Later Magnetic tape became the most popular method of storing data
• Over the years this technology has be used in the forms of Tape
cassette, Floppy Disks and Hard Drives
3. • Another common form of storage used is optical
storage - this comes in the form of CDs, DVDs
and Blu-Ray Disc
• More recently, Flash memory devices have gained in
popularity, mostly in the form of removable storage such as
Flash Drives and SD cards
•
• Now many computer manufactures are using Flash
technology to make Hard Drives over Magnetic
and optical forms of storage due to the much
faster speeds and longer life for the device
4. Cloud storage
• Today, one of the quickest growing forms of storage is Cloud Storage
• Cloud Storage is not a physical storage device that you can walk into a
shop and buy like you can with a Flash Drive or Hard Drive
• Instead companies offer Cloud Storage in a different location from you
and your device, you store and access stored information through the
use of internet technologies
5. • Users/Companies store their data most commonly on the
Hard Drive on their device
Or they might have a server in their office building where
data is stored, or multiple servers if they store a lot of data
• This can prove expensive if you are a small business,
servers are very expensive for quality equipment
• Servers use a lot of power and require cooling to keep
them functioning
• With this comes the need of specialized staff, space for the
equipment, and software to manage all the processes
Why use Cloud storage?
6. • The idea of cloud technology is to eliminate all these requirements
• Instead of a company dealing with all these requirements, they can
go to a cloud storage provider who has all this setup and simply
charges an annual fee for storing data on their equipment
• Cloud technology still allows advantages of shared storage where
multiple devices can access the same information
7. • Cloud Storage is not actually a cloud like some may think, instead
Cloud Providers own and operate large sites with buildings
containing large numbers of Servers
• These buildings are known as Data Centres
• Cloud Providers run much like an
ISP or a Power Company
• A Cloud Provider purchases and sets up equipment and servers
for storage
• This includes the power, cooling, and technical staff necessary
for the site
How does it work?
8. • Cloud providers then allow others to use and store data on their
equipment for an annual fee
• This means a company or business can simply rent the storage and
services they need instead of setting up expensive equipment
themselves
• If an organization finds they need more storage or services they
simply make an agreement with the Cloud provider and pay for the
increased service

9. • One Cloud Storage provider may have hundreds or even
thousands of different organizations storing and accessing data
from them
• Clients access these facilities through the use of the internet
Cloud Provider
10. • There are many cloud storage providers today
• Most commonly, both Google and Microsoft offer cloud storage
through the use of Google Drive and OneDrive
• Some providers offer limited cloud storage for free when using their
applications, such as free OneDrive storage when you create a
Microsoft account
Cloud storage providers
11. • Many vendors charge a monthly subscription for additional storage
space
• There are also private Cloud providers, these organizations are not
so well known, but offer private cloud services to organizations and
businesses
• Cloud Providers may be based globally and have Data centers across
the globe, or some are based locally in their country of operation
12. • There are now a range of applications that use Cloud Technology to
allow storage and synchronization of data across multiple devices
• For example you can now use an Online version of Microsoft Office for free
with a Microsoft account
• Although these applications are more basic and don’t include all the
features of the full software, it allows users to edit and create basic
documents, spreadsheets, etc. online and stores the work on the user’s
Cloud OneDrive Storage
• You are then able to access that data and online applications from any
device (your Smartphone, Tablet – can be iOS or Android) providing
you have access to the internet and work in real-time with other users
collaborating on the development of the document, video, images,
workbook etc etc
