One of the core principles behind Celtix Enterprise is the idea that services should be deployed as smart endpoints. A smart endpoint has all of the functionality to send and receive messages as specified by the service's contract. It does not rely on a central server and is more flexible in terms of resources and deployment options.
The Celtix Advanced Service Engine is designed to create smart endpoints. Service's built with Celtix Enterprise can be deployed as standalone processes that are completely autonomous. You can also deploy them into the lightweight service container provided. Either mode of deployment provides you a lightweight smart endpoint.
