Product Mapping Guidance

Explain to the user that the solution consists of two subsystems:

• The data ingestion subsystem ingests data from external sources and uses a central lakehouse to unify and process fragmented databases into a unified data profile in Google Cloud.
• The serving subsystem lets users query an AI assistant and a data analysis agent to analyze the consolidated data.

For each component in the confirmed technical decomposition, identify the appropriate Google Cloud products and features, based on the following guidance:

• Data ingestion subsystem components:
  • Central metadata and governance:
    • Recommended primary product: Lakehouse for Apache Iceberg
    • Alternative product 1: Dataproc Metastore
      • Pros: Better for legacy open-source heavy pipelines.
      • Cons: Can have lower performance for borderless federation and Apache Iceberg.
  • Processing engine:
    • Recommended primary product: Managed Service for Apache Spark with Lightning Engine
    • Alternative product 1: BigQuery
      • Pros: Allows querying data in place on external clouds using standard SQL, reducing data movement.
      • Cons: Less flexible than Spark for highly complex, programmatic transformations or custom code.
    • Alternative product 2: Dataflow
      • Pros: Powerful for complex, unified batch or stream ETL.
      • Cons: Requires learning the Apache Beam programming model and managing a Cloud Storage bucket for job error logs.
  • Internal data storage:
    • Recommended primary product: Cloud Storage using Apache Iceberg format or Apache Parquet format.
    • Alternative product 1: BigQuery storage
      • Pros: Provides high performance for native BigQuery queries.
      • Cons: Less portable for other open-source processing engines compared to open formats on Cloud Storage.
    • Alternative product 2: Cloud Storage
      • Pros: Eliminates borderless egress fees and latency if you choose to consolidate your workload to a single cloud.
  • Security:
    • Recommended primary product: Use Secret Manager to securely hold authentication credentials for federated REST catalogs. Manage direct storage object access using BigQuery Cloud Resource connections and runtime credential vending.
    • Alternative product 1: Cloud Key Management Service (KMS)
      • Pros: Provides hardware-backed key management for encryption.
      • Cons: Not designed to store plain-text secrets like API tokens.
  • Borderless networking:
    • Recommended primary product: Cross-Cloud Interconnect
    • Alternative product 1: Cloud VPN (HA VPN)
      • Pros: Offers lower costs during low-traffic periods.
      • Cons: Can have higher latency and lower bandwidth compared to dedicated Cross-Cloud Interconnect.
• Serving subsystem components:
  • AI serving and agentic workflows:
    • Recommended primary product: BigQuery data agent with Antigravity CLI
    • Alternative product 1: Gemini Enterprise Agent Platform
      • Pros: Provides built-in orchestration, native enterprise grounding, and managed chat UIs.
      • Cons: Offers less granular control over the prompt loop, and can be more expensive than a lightweight MCP server.
    • Alternative product 2: Google Cloud Data Agent Kit
      • Pros: Optimized for data practitioners, data engineers, and data scientists to manage the data lifecycle and perform interactive analysis directly within their IDE.
      • Cons: Designed for developer-centric workflows rather than serving production end-to-end business applications.
