How does communication occur in the Hub and Spoke architecture?

In Hub and Spoke architecture, communication occurs through a central hub, which serves as the intermediary for all interactions among the various systems, or "spokes." This design simplifies data flow and management by channeling all communications through a single point, thereby reducing the complexity that would arise if all systems communicated directly with one another.

When a spoke system needs to exchange data or information with another spoke, it sends the request to the hub. The hub then processes the request and routes the information to the appropriate spoke. This approach enhances security, facilitates better control over data exchange, and allows for easier monitoring and management of the integrations.

Using a hub to manage communications not only streamlines the architecture but also allows for easier updates and changes, since adjustments can be made at the hub level without needing to alter the connections between every spoke system. This increases the overall efficiency and scalability of the integration solution.
