I have been reading about SalesForce lately. I have seen SalesForce API's included in Mule ESB.
What I am gathering is that Sales Force, (or more specifically the Force.com component) is actually a PaaS, used by Mule and other providers.. However, it seems to be a collection of API's instead of a fully integrated PaaS, but I am inexperienced in PaaS.
Is this correct. What other impact does Sales Force have in the market
