Cloud Computing

Cloud computing is considered to be a term that encompasses many similar producers that deliver hosted services over the internet.  Cloud computing however is different than normal hosting because principally it is sold on demand and charged by time (i.e. per minute/hour).  The service can be tailored to the users wants, whether or not they desire services maximally or minimally during that period of time.  The host provides all the services that the customer or client is paying for.  The term cloud is used mainly because the thought and the diagram of the internet is compared to a cloud.  A cloud can be a private or public structure or infastructure.  These reliable and depended upon services are all delivered through data centers and are stored on servers with seperate technological levels.  Those who point out the cons of cloud computing tend to focus on how encompassing and vague the definition of cloud computing is.
