"The map is published by Appiro, a professional services firm
that sells solutions for the Salesforce platform, and consults on
strategy. The map is available at
http://www.appirio.com/ecosystem/. At first glance, it is not the
most intuitive guide you'll ever see. But with a few clicks, the
picture emerges. The grid lists applications and services within
each major platform, and charts companies offering solutions. Some
solutions are linked to more information, others are not."
