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.

Net Neutrality

Net Neutrality or Network Neutrality is a concept that is pushed very hard by its advocates.  This act or principle promotes that there are no restrictions on the content of a site and that all internet traffic is equal.  Advocates of this principle have come up with three different rules or ethics of this principle.  The first is "absolute non-discrimination" which can be deciphered as the main concept of neutrality, which is that all internet platforms should be treated equally.  The second "rule" is "Limited Discrimination without quality of service tiering: which state that quality of service discrimination is allowed but there can be no special fee implemented for higher quality services.  The third and final is "Limited Discrimination and Tiering": meaning that higher fees may be implemented for higher quality however there may be no exclusivity in co tracts.  Opponents to this concept argue that rich citizens will be enjoying higher quality services, and all the median income families and citizens will be forced to put up with bad quality and slow connections. Large hardware companies are infamous for opposing network neutrality.
