Application Services
Application services represent server-based functionality.
Analyst Service
The Analyst Service is an application service that runs the Informatica Analyst application in the Informatica domain. The Analyst Service manages the connections between service components and the users that log in to Informatica Analyst. The Analyst Service connects to a Data Integration Service, a Model Repository Service, a Metadata Manager Service, and a Search Service. The Analyst Service also specifies a flat file cache directory and a directory for business glossary export files.
When you configure the Analyst Service, connect it to a Data Integration Service to run profiles, scorecards, and mapping specifications. You can also connect the Analyst Service to a Data Integration Service that runs Human tasks. Connect the Analyst Service to a Model Repository Service to identify a Model repository.
Specify a flat file cache directory to store temporary data from flat files that you upload. Specify a business glossary directory to stores temporary files that you export from the Business Glossary.
Cluster Service
The Informatica Cluster Service is an application service that runs and manages all the Hadoop services, Apache Ambari server, and Apache Ambari agents on an internal Hadoop cluster. If you choose the internal cluster deployment mode, you need to create the Informatica Cluster Service before you create the Catalog Service. Then, you can pass the Informatica Cluster Service value to when you create the Catalog Service.
Informatica Cluster Service distributes the Hortonworks binaries and launches the required Hadoop services on the hosts where the internal cluster runs.
The Informatica Cluster Service distributes the Hortonworks binaries and launches the required Hadoop services on the hosts where the embedded cluster runs.
You can deploy Informatica Cluster Service on hosts where Centrify is enabled. Centrify integrates with an existing Active Directory infrastructure to manage user authentication on remote Linux hosts.
Note: Informatica does not integrate with Centrify to manage or generate keytabs.
You can deploy Informatica Cluster Service on hosts that provide access using JSch SSH encryption algorithms.

Catalog Service
The Catalog Service is an application service that runs Live Data Map in the Informatica domain. The Catalog Service manages the connections between service components and the users that have access to Live Data Map and Live Data Map Administrator.
The catalog represents an indexed inventory of all the configured data assets in an enterprise. You can find metadata and statistical information, such as profile statistics, data asset ratings, data domains, and data relationships, in the catalog.
Content Management Service
The Content Management Service is an application service that manages reference data. A reference data object contains a set of data values that Live Data Map searches while performing data domain discovery on source data. Data domain discovery finds inferred business semantics based on column data. Examples include Social Security number, phone number, and credit card number.
The Content Management Service uses the Data Integration Service to run mappings to transfer data between reference tables and external data sources.
