Chapter 1. Red Hat Fuse and Red Hat Decision Manager

Red Hat Fuse is a distributed, cloud-native integration platform that is part of an agile integration solution. Its distributed approach enables teams to deploy integrated services where required. Fuse has the flexibility to service diverse users, including integration experts, application developers, and business users, each with their own choice of deployment, architecture, and tooling. The API-centric, container-based architecture decouples services so they can be created, extended, and deployed independently. The result is an integration solution that supports collaboration across the enterprise.

Red Hat Decision Manager is an open source decision management platform that combines business rules management, complex event processing, Decision Model & Notation (DMN) execution, and Red Hat Business Optimizer for solving planning problems. It automates business decisions and makes that logic available to the entire business.

Business assets such as rules, decision tables, and DMN models are organized in projects and stored in the Business Central repository. This ensures consistency, transparency, and the ability to audit across the business. Business users can modify business logic without requiring assistance from IT personnel.

You can install Red Hat Fuse on the Apache Karaf container platform or Red Hat JBoss Enterprise Application Platform and then install and configure Red Hat Decision Manager in that container.
