i was looking at the documentation site
https://access.redhat.com/documentation/en/
i see a section called Fuse source with FUSE ESB, FUSE Message Broker etc., then there is JBOSS FUSE, JBOSS FUSE SERVICE WORKS.
what is the difference between the two? Please shed some light.
FuseSource was a company that created the Fuse ESB product. Red Hat acquired FuseSource 4 years ago and the product Fuse ESB was rebranded as JBoss Fuse.
So you should look at JBoss Fuse as that is the current product from Red Hat.
