WSO2 Carbon is the foundation of WSO2's componentized SOA platform. Carbon provides the framework for all of the core functionality -- data services, ESB/routing, process management, registry, monitoring, and security - allowing you to plug in these components as necessary. The ESB and additional modules for governance and identity are good, and the process server is also decent, and with Carbon the whole is greater than the sum of the parts.
