Cloud Computing


Cloud computing is the simple possibility to access  via internet servers, storage, databases and a broad range of applications. The ressources are not on your own Computer, they are distributed in a pool of computerressources and managed by service-providers.
 In most cases we are talking about Public Clouds - for the broad public, but a lot of companies have already there Private Clouds because of confidentiality reasons.
In General exists 3 different types of Clouds:
-Infrastructure Cloud is the most simple form, where only hardware and access to data-management
  is offered. You rent Hardware and maintenance.
-Platform-Cloud, the middle type,  where the user can control self-loaded programs and data,
  using networks, storage and dataprocessingsystems.
-Application-Cloud, the highest form, where the Client uses applications not on his own Computer,
  he rents finished programs in the cloud.




The big advantages are:
no maintenance and administration costs, nearly indefinitely storage capacity and global usage of data and applications.


Risks are:
lack of Internet access, no confidentiality for intelligent hackers (US-government can see it all)


For me personally: I have my Music, my photos, and a lot of my games everywhere available with
all my equipment, smart phone, tablet, laptop or desk top.
