GCP Data Architect c2c requirement IAM Data Modernization

Highly Preferred OCP Exp

Project/Program

 Identity & Access Management (IAM) Data Modernization – migration of an on-premises SQL data warehouse to a target-state Data Lake on Google Cloud (GCP), enabling metrics & reporting, advanced analytics, and GenAI use cases (natural language querying, accelerated summarization, cross-domain trend analysis) leveraging PySpark-based processing, cloud-native DevOps CI/CD pipelines, and containerized deployments on OpenShift (OCP) to deliver scalable, secure, and high-performance data solutions.

About Program/Project

The IAM Data Modernization project involves migrating an on-premises SQL data warehouse to a target state Data Lake in GCP cloud environment. Key highlights include:

• Integration Scope: 30+ source system data ingestions and multiple downstream integrations
• Capabilities: Metrics, reporting, and Gen AI use cases with natural language querying, advanced pattern/trend analysis, faster summarizations, and cross-domain metric monitoring

Benefits:

• Scalability and access to advanced cloud functionality
• Highly available and performant semantic layer with historical data support
• Unified data strategy for executive reporting, analytics, and Gen AI across cyber domains

This modernization establishes a single source of truth for enterprise-wide data-driven decision-making.
