+
+    In practice, it's useful to encapsulate multiple related services into a service group and present them externally as a new service 
+    in order to avoid spreading too much local complexity to the larger scope of the system. In the past we had to write/generate some code or 
+    at least some scripts for each new service. Let us put aside the development and maintenance costs of these new codes/scripts themselves. 
+    The new configuration files/tables and the new setup and deployment brought by the new services keep increasing the maintenance complexity of the entire system.
+    From the perspective of each individual service, it seems that every configuration item is necessary; but from the perspective of the whole system, 
+    too many configuration items are repeated in different service nodes. The more redundant configuration, the more messy.
