Integration Route Planner
Pick the systems you already have. The tool counts the connections needed point-to-point versus through a central hub, and builds a preparation checklist.
READING THE RESULT
Point-to-point vs hub
With direct connections every pair of systems needs its own link: for n systems that is up to n·(n−1)/2 integrations. A hub (bus or middleware service) needs only n links but adds one more component to maintain.
For two or three systems, direct links are usually simpler. From four upward a hub more often pays off. This is a guide, not a verdict — the real answer depends on volumes and frequency.
