Architecture
Clear ownership. Better connections.
Give every system a defined role so people can follow the work and resolve problems.
When applications exchange information, responsibility can become harder to see. An order exists in one system. A payment changes in another. A message has to carry the result between them.
The design question is who owns each decision. Stellar Orbit handles the commercial journey and order context. Stellar Pay handles payment responsibilities. IntellaSwitch carries events between independent systems.
That separation gives the workflow a structure people can inspect. When a connection needs attention, the team has a clearer place to begin. Good integration preserves the meaning of the work as it moves.
