For information on running ATG Self Service and ATG Knowledge together in a production (or customer-facing) environment see the ATG Knowledge Configuration Guide.
You must run ATG Self Service on an ATG instance that is accessed by external users. This instance must have the following characteristics:
It must run your site application (your customer-facing web application).
Any commerce-related items (catalogs and price lists) are read-only; therefore you can keep them synchronized across ATG instances by periodically publishing the current data to all instances simultaneously. For the order repository, however, the data is constantly being modified by customers, so all ATG instances must point to the same set of database tables.
You should run a separate ATG instance that has ATG Service Administration and ATG Content Administration running together.
