You can create an Informatica domain with one node and run all application services on the same node. If you create an Informatica domain with multiple nodes, you can run the application services on separate nodes. When you plan the application services for the domain, consider system requirements based on the services that you run on a node.

The following table lists the minimum system requirements for a node based on some common configuration scenarios. Use this information as a guideline for other configurations in your domain.
