• The PaaS layer accounted for nearly a quarter (24%) of the total public cloud revenue in 2012, and will experience the fastest growth – a projected  CAGR of 41% between 2012 and 2016.


• The infrastructure SaaS sector, which does not include enterprise SaaS revenue, represented 25% of total cloud revenue in 2012 and is expected to generate a 29% CAGR through 2016.


• Publicly traded companies comprise 23% of the cloud vendors tracked, and generate  78% of the total revenue. The majority of vendors are still below the $5 million revenue threshold; vendors that constitute the cloud ‘midmarket’ (between $5 million and $50 million in revenue) accounted for 25% of total revenue in 2012.
