Informatica Power center Architecture

Informatica Power center Architecture

Informatica power center is a service oriented architecture that provides capability to share service and resource across multiple machines.

Domain: It is primary component of informatica power center,  domain is managing and administrating various services in informatica power center

Node: Node is a logical representation of machine in domain, one domain can have multiple nodes.

We are hosting domain in master gateway node, node can be configured to run integration service as well as repository service i.e. application service.

Application service:  It comprises of informatica services like (power center integration service , data integration service,meta data manager service and power center repository service).

As Informatica power center is service oriented architecture all operation done by it’s client manage through services.

      a)     Power center integration service: Power center integration service works as controller and it gives instruction to power center workflow manager to run workflow based on logic written in power center designer mapping.

The Integration Service reads workflow information from the repository. The Integration Service connects to the repository through the repository service to fetch metadata from the repository.

It gives instruction to power center clients to extract, transform and load in other words read, transform and write data between source and target.

      b)     Power center repository service: It keeps all the Metadata information and storing into repository database.

It accepts & rejects request to create or modify metadata into repository database, this is also getting request from integration service to get metadata for running workflow.

      c)    Metadata manager service: It is used to analyze metadata from various metadata repository.

It uses power center workflows to extract metadata from different systems like application, BI system, Data modelling and RDBMS metadata source.

Power center Clients: It’s comprises of power center designer, power center workflow manager, power center workflow monitor, power center repository manager and power center metadata reporter

Power center designer: It is used to create mapping (pipeline) which is combination of source, target and transformation.

Power center workflow manager: This used to run mapping and it has various task to manager source and target and running workflows.

Power center workflow monitor: It is used to monitor execution of workflow and session.

power center repository manager: used to manage repositories and code migration from one environment to other.
