Reference blueprint details
Google Vertex AI Stack
Description
The comprehensive Google Cloud AI stack covering Vertex AI, Gemini, Agent Builder, and the full breadth of GCP infrastructure and data services. From model serving and MLOps through BigQuery analytics, GKE orchestration, and Cloud Run deployment. Includes security (Cloud Armor, Model Armor, DLP), observability (Monitoring, Logging, Trace), and specialized AI services (Document AI, Healthcare API, Dialogflow CX).
Use cases
- Multi-modal AI applications
- Large-scale document understanding
- Enterprise search and retrieval
- Grounded generation with Google Search
- Conversational AI with Dialogflow CX
- Healthcare AI with FHIR integration
Tradeoffs
The most comprehensive single-cloud AI platform on GCP. Deep integration across 60+ services but full cloud lock-in. Strong enterprise security and compliance features. Requires significant GCP expertise for optimal configuration. Best for organizations with existing GCP investments.
