Hi Ana, I'd recommend you to look at some of the stats gathered by Cisco's Cloud Consumption team - here's a pretty interesting infographic to start with: http://www.cisco.com/c/dam/en/us/services/collateral/se/cloud-consumption-infographic.pdf

And there's more here: http://www.cisco.com/web/solutions/trends/cloud/cloud-consumption-services.html

Let me know if this fits your needs!
