Informatica Domain - It is an administrative unit consisting of nodes and services. These nodes and services can be further categorized into folders and subfolders. There are basically two types of services in the Informatica Domain- Service Manager and Application Services you’ll be learning in Informatica server Architecture tutorial. While the former is responsible for authenticating/authorizing the loggings and running the application services, the latter represents the integration services, repository services, and reporting services. Listed services are explained in detail below in this Informatica Cloud Architecture.
Repository Service - This service maintains a connection between the clients and the PowerCenter repository. It is a multi-threaded process that fetches, inserts and updates the metadata. It also maintains a uniformity within the repository metadata.
Nodes - Nodes are the computing platforms where therefore mentioned services are executed.
Reporting Service - Reporting services are responsible for handling the metadata and allowing other services to access the same.
Integration Service - This service is the engine that executes the tasks created in the Informatica tool. It is nothing but a process inside the server waiting for the tasks to be assigned. As soon as a workflow is executed, the integration service gets the details and executes it.
