Load balancing remote services

Hi Folks,

The ECF wiki now has example code for doing dynamic load balancing of remote services.

This implementation uses a JMS Queue (via ActiveMQ implementation of JMS) to do the dynamic load balancing of ECF remote service requests/method invocations.

The thing that I like most about this is that it's extremely simple, small...and doesn't require any special/custom code to use. Clients/consumers just lookup/use a remote service, and upon usage the service implementation load balances the requests among an arbitrary set of target servers.

ECF 3.1 is being released on Monday next (10/12/2009), and there are some exciting additions:

  1. REST API - An extension of the ECF remote services API to allow interoperation between OSGi remote services and REST-based services
  2. Distributed EventAdmin - a Distributed implementation of the OSGi EventAdmin service, that uses JMS/ActiveMQ for transport (and/or other providers)
  3. Lots of small improvements on ECF remote services, as well as examples and additional documentation
  4. File-based Discovery - a contribution from Siemens for doing remote service discovery using a static endpoint-URI exposed via an xml format
Here are the release review slides.
