3. 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

4. •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

5. 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

6. •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?

7. •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

8. •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?

9. •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

10. •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

11. •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

12. •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

13. •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
