Cloud ComputingWhat is it?
Using a network of remote servers hosted on the internet to store, manage, and process data, rather than a
local server or a personal computer.
What remote provision does cloud computing offer?
Cloud computing gives word processing, spreadsheets and presentation software facilities providing an
internet connection is established and maintained.
What are the advantages of cloud computing?
Cost Reduction – the hardware of a server room can be incredibly expensive so by choosing cloud
computing, you can be paying a fraction of the cost and still be able to access the same facilities.
Security - cloud providers are under a lot more scrutiny and must comply with established standards
resulting in your data being kept safe and less likely to fall to security breeches.
Reliability – Your data is not stored on only one server, it is stored on multiple therefore if one server
experiences failure, you will still be able to access your data
Always accessible files – Files can be accessed by any device as long as they are connected to the internet.
What are the DISADVANTAGES of cloud computing?
Downtime – if your internet goes down, you cannot access your data in the cloud
Security – one the one hand, security can be viewed as an advantage, as explained above however, in the
past there have been major security breeches due to the need to keep on top of security and have employees
always ensuring security is up to date.
What companies currently offer cloud computing?
Microsoft, Google, Amazon
How much does cloud computing cost?
The prices can vary however, it can range from around £5 to £15 per month depending on which company
you decide to employ.
For what reasons might a company choose to use cloud computing?
An employee can access files from home and use the software provided by the company for example word
processing or presentation remotely. Furthermore, for the manager or a business, it is a lot cheaper to use
that to set up your own servers which need maintaining for security purposes , etc. In addition, traditional
storage needs backing up so it is not lost however, with cloud computing, the data is backed up in many
locations so if one server goes down, the data can still be accessible without impacting those using it.
Finally, collaboration on documents can be made so much easier with real time updates of edits of
colleagues.
