This document discusses using microservices and business process management (BPM) together to improve business processes. It provides an overview of JBoss BPM Suite for defining and managing business processes and rules, and JBoss Fuse for creating microservices and integrating applications and data sources. The document also provides examples of using the JBoss BPM REST API to start and interact with processes, and the JBoss Fuse REST DSL for exposing microservices via REST.
