ACE Tutorial 022

Using Service Configurator Framework

When building distributed systems, there will almost certainly be multiple processes or services running at all times. It is helpful if these services can (re)configured and control at installation-time or run-time. In this tutorial, we illustrate how to configure services in a fine-grained manner, rather than having to stop and restart all services in an application.

The examples we show are based on the Component Configurator pattern, which enables a service to be started, removed, suspended or resumed dynamically. This pattern decouples the implementation of a service from its (re)configuration. Thus, new services can be added or unnecessary services can be suspended or removed.

In this tutorial, we will use the simple server and client which we developed and used in our tutorial 005 as the base and modify it as needed.
