Sample Solution

Cloud Computing

Cloud computing is the delivery of on-demand computing services, from applications to storage and processing power, typically over the internet and on a pay-as-you-go basis. Rather than owning their own computing infrastructure or data centers, companies can rent access to anything from applications to storage from a cloud service provider. The cost of cloud computing gives small businesses and start-ups access to the same software tools that larger competitors have. Advantages of cloud computing include back-up and restore data; improved collaboration; and excellent accessibility. Downtime is often cited as one of the biggest disadvantage of cloud computing. Since cloud computing systems are internet-based, service outages are always an unfortunate possibility and can occur for any reason.

The Documentation includes specific facts, description, quotes and references to authoritarians. Numerical examples are also used to support the requirements. The following statement provides evidence that: “the average person is likely to be spotted by CCTV 300 times.” The article end with a conclusion. The conclusion tries to persuade the reader to accept the author’s arguments by raising a series of rhetorical questions: “but do we really want to be monitored around the clock, regardless of wherever we are? If the man in charge of the system worried about Big Brother, why shouldn’t we be?
