Cloud computing



What is Cloud computing?

Cloud computing is where you focus less on the physical hardware and more on storing information/ websites/ data online. Cloud computing is where you pay someone to host a server and but you only pay for what you use. E.g. when you buy a 10TB server and host your website on their. You are paying to run that server whereas with the cloud you only pay for what you use.



Costs less – Pay for what you need    You giving someone else your information/ data and trusting them to keep it safe.     
Scalable – can increase/ decrease storage when needed    Security, you are trusting someone to keep your data secure.     
Access data from anywhere         
         
        

 
  Localized storage   
 
  
Advantages   

You are in control of your own data

 Disadvantages       

    Expensive to maintain and run     
    costs more if you need more space     
    You pay whether you are using the space or not.     
    Can only access your data when you are in that network     
    If the physical hardware is damaged (fire, water, stolen etc.) you can’t get it back
