There is no doubt that Cloud Computing is a reality and not a tendency. A search on Google Trends for the term "cloud computing" brings an interesting result. It shows an increasing level of curiosity in 2008 that accelerates through 2009, reaching its highest levels in 2011/2012. After that it declines. That does not indicate a lack of interest; it may actually demonstrate that Cloud Computing is leaving the hype to become part of the daily agenda of organizations. A few years from now we will probably refer to Cloud Computing as just "Computing", since almost everything will be, by default, on the Cloud.
