We are in the midst of a transition to cloud based computing as the primary model for data center workloads. According to “Independent Shipment Analysis, Cisco Systems”, by 2014, over 50% of all workloads will be processed in the cloud; traditional computing will be in the minority. It is projected to reduce overall tech spending by $30B-$39B in 2013, replacing 14% of global on-premise spending in 2020. This transition translates into a cloud computing market growth rate of 37% from 2008 to 2013, from $13B to $55B. According to another source, the total cloud market was $20B in 2011 and is expected to reach $26.4B in 2012, equating to 32% growth year over year. Gartner pegged the expected growth rate between 2011 and 2012 at 37% (from $14.5B to $22.1B).
