Over the course of 14 years, salesforce.com has grown at an extremely rapid pace. It has taken salesforce.com 12 years to reach $2B in annual revenue. In comparison, it took Microsoft 16 years, Oracle 17 years, and SAP 23 years to reach this same milestone. As with any high-growth and fast-paced company, the focus for internal based integrations is on near term delivery. Teams work at a whirlwind pace to satisfy business requirements and move the business forward. Unfortunately over time, this can lead the teams to focus on delivering point-to-point integrations rather than designing loosely coupled integrations. This ultimately results in a complex structure that is not only difficult to maintain but costly too.
