The "Clustered Remoting For Spring Framework" (or Cluster4Spring) is alternative implementation of remoting subsystem included into Spring framework.
Clustered remoting scheme
While implementation of remoting in Spring is great, it has several limitations that are quite important and must be taken into consideration when building large enterprise-level distributed system.
Briefly, these limitations relate to the point-to-point model of remoting supported by Spring - generally speaking, the client may use only one instance of remote service. It is obvious that having only such a scheme of remoting, it is hard to develop fault-tolerant systems and implement some kinds of load balancing.
Another feature, which is currently missing in remoting subsystem offered by Spring framework, is lack of the ability to dynamically discover remote services.
The main purpose of Cluster4Spring is to extend remoting system of Spring framework and overcome limitations mentioned above.
