Kubernetes Fees

In Informatica PowerCenter, the Integration Service is the core application service that executes workflows and sessions to run Extract, Transform, Load (ETL) processes. Often called the "heart" of Informatica, it acts as the engine that moves and transforms data from sources to targets.

Key Functions

• Reads Metadata: Connects to the Repository Service to fetch workflow, mapping, and session definitions.
• Orchestrates Workflows: Locks workflows, triggers tasks (like commands or decisions), and manages execution schedules.
• Spawns DTM Processes: For each session run, the Integration Service creates a Data Transformation Manager (DTM) process. The DTM handles the actual heavy lifting—reading source data, applying transformations, and writing to target databases or files.
• Loads Targets: Delivers the cleaned, transformed, and aggregated data into the final destination systems

The main difference is that Informatica PowerCenter is a traditional on-premises, server-based ETL (Extract, Transform, Load) tool, whereas Informatica Cloud—officially known as Informatica Intelligent Cloud Services (IICS)—is a modern, cloud-native, multi-tenant SaaS platform.

Core Differences

Feature Informatica PowerCenter Informatica Cloud (IICS / IDMC)
Deployment Model On-premises or private infrastructure (requires installing UNIX, Linux, or Windows servers) Cloud-native SaaS platform; uses a lightweight local component called a Secure Agent
Architecture Client-server architecture (requires PowerCenter Client for GUI and Server for processing) Microservices-based architecture managed via a web browser UI
Data Processing Approach Primarily traditional ETL (Extract, Transform, Load) moving data to and from physical servers Emphasizes ELT (Extract, Load, Transform) and pushdown optimization leveraging cloud data warehouse power
Scalability Manual scaling tied directly to the limits of physical on-premises hardware capacity Elastic and automatic scaling provided by cloud infrastructure
Installation & Maintenance Manual installation, patching, and database repository management Automatic updates managed by Informatica; minimal local setup
Connectors & Ecosystem Best for legacy, relational, and on-premises databases; cloud integration often requires custom setup 500+ pre-built native connectors for modern cloud apps (AWS, Azure, Snowflake, Salesforce, Google BigQuery)
Current Market Status In maintenance/support mode; new feature development has shifted away from it Active flagship development platform (part of the broader Informatica IDMC ecosystem)

Key Operational Changes If Moving to Cloud (IICS)

• User Interface: PowerCenter uses a rich desktop client application, whereas IICS is 100% web-based.
• Parameter Files & Overrides: Parameter handling, taskflows, and command tasks differ (e.g., parameter files in IICS must be passed via mapping tasks or managed through Cloud-hosted parameter files rather than local server directories).
• Lifecycle: PowerCenter standard support has transitioned/phased out, and industry demand has shifted heavily toward cloud-native data engineering and IICS/IDMC.
