Application services represent server-based functionality. Application services include services that can have multiple instances in the domain and system services that can have a single instance in the domain. System services are created for you when you create the domain. After you complete the installation, you create other application services based on the license key generated for your organization.
When you create an application service, you designate a node with the service role to run the service process. The service process is the run-time representation of a service running on a node. The service type determines how many service processes can run at a time.
If you have the high availability option, you can run an application service on multiple nodes. If you do not have the high availability option, configure each application service to run on one node.
Some application services require databases to store information processed by the application service. When you plan the Informatica domain, you also need to plan the databases required by each application service.
