Publish-Subscribe Model

Part of the CloudQix Glossary of Integration Architecture Terms, this page explains how publish-subscribe model shapes modern system integration.

Definition 

Publish-Subscribe Model is an integration concept that defines how systems communicate, coordinate, or exchange data within an architecture.

In-Depth Explanation 

Publish-Subscribe Model influences how integration logic is organized and executed across connected systems.

Different integration approaches affect scalability, maintainability, and the level of system coupling.

CloudQix supports publish-subscribe model by enabling API-driven and event-based integrations aligned with modern architecture principles.
