Based on James feedback, I have adapted the categories. I will create
a wiki page on camel wiki to show the different options
1. Loadbalancing
loadbalance() : http://camel.apache.org/load-balancer.html
2. Clustering
2.1. Same JVM & CamelContext
seda:// : http://camel.apache.org/seda.html or direct://
and threads()
jms:// or activemq:// and threads()
2.2 Different JVM & CamelContext
2.2.1. Suitable for solutions running in standalone mode or deployed
in Web Application Server (different WAR/EAR)
vm:// : http://camel.apache.org/vm.html or jms:// - activemq://
2.2.2. Between different instances of OSGI servers (SMX4)
nmr:// : http://camel.apache.org/nmr.html or jms:// - activemq://
2.2.3. If message persistence is required
jms:// - activemq://
4. Cloudcomputing
4.1 Cassandra
It could be interesting to create a Cassandra endpoint to allow to consume
info/camel messages from Cassandra DB (NOSQL database) or to push there
camel message (using id + binary stream). It might also make an interesting
aggregator implementation since its also distributed & can support multi-master
4.2 camel-terracotta
Extends the SEDA component
