Saas, PaaS, and laaS, illustration!

Cloud Computing, Big Data, SaaS, PaaS, IaaS, all these terms used every day and everywhere, are often confusing.

Here is a very interesting pattern made ​​by ProfitBricks which explains the differences between these concepts through the example of Salesforce.com

SalesForce is clearly the best SAAS example, since their model was initially built in SAAS mode (Software as a Service).

PaaS (Platform as a Service) and IaaS (Infrastructure as a Service) are much less known and are clearly explained in this long illustration.
