Borderless open data lakehouse agentic AI system

Follow this workflow to help users design and implement a custom multi-product solution in the cloud for a given workload, use case, or requirement.

Product Renaming & Terminology

When generating solution designs, architecture diagrams, and documentation, use the updated Google Cloud product names. For details on legacy vs. updated product names and terminology, see references/product_renaming.md.

Workflow

The solution design and implementation workflow consists of the following phases:

• Phase 1: Requirements discovery and analysis: Analyze the workload's

requirements, constraints, dependencies, and current state.

• Phase 2: Solution design: Build a technology stack, architecture, and

deployment configuration for the workload based on Google Cloud design best practices and recommendations.

• Phase 3: Implementation plan: Generate automation

and instructions to deploy the solution.

• Phase 4: Solution validation: Validate that the deployment meets the

requirements of the workload.

Phase 1: Requirements discovery and analysis

• [ ] Step 1: Discover requirements: Understand the functional and

non-functional requirements, business goals, and current state (if any) of the workload, including its architecture, dependencies, and constraints. Use the following questions to guide the requirements discovery process:

• What are your primary data sources?
• How do you manage and federate metadata across your data sources?
• What are your security and credential management requirements?
• What are the analytical and computational requirements to join and

transform this borderless data?

• What types of natural language prompts or user queries do you expect AI

agents or end-users to execute against this data?

• [ ] Step 2: Identify components: Based on the requirements analysis,

identify the components of the workload and their relationships. Also identify any borderless components, hybrid components, or on-prem components that the solution needs to integrate with.

• [ ] Step 3: Generate component decomposition: Generate a technical

decomposition of the components of the workload.

• [ ] Step 4: Ask for confirmation: Ask the user to confirm whether the

generated technical decomposition matches their workload requirements.

• [ ] Step 5: Iterate: If the user requests changes, then generate an

updated technical decomposition, and ask the user to confirm the changes. Continue iterating until the user confirms the technical decomposition.

Phase 2: Solution design

• [ ] Step 1: Retrieve relevant Google Cloud documentation: Use available

search or fetch tools to read the content of the following Google Cloud documentation to ground the guidance that you generate in the remaining steps of this phase before proceeding.

• Build hybrid and borderless architectures using Google Cloud
• Build a borderless open data lakehouse
• Implement agentic analytics workflows for distributed data
• Analytics Hybrid and Multicloud Pattern
• Google Cloud multi-regional deployment archetype
• Network segmentation and connectivity for distributed applications in Cross-Cloud Network
• Patterns for Connecting Other Cloud Service Providers with Google Cloud

Important: Use the content that you retrieve from Google Cloud documentation to ground the guidance that you generate in the remaining steps of this phase.

• [ ] Step 2: Map components to Google Cloud products: For each component in

the confirmed technical decomposition, identify the appropriate Google Cloud products and features, based on the guidelines in references/product_mapping.md.

• [ ] Step 3: Create architecture diagram: Create an architecture diagram

that shows the components, their relationships, and data/control flows.

• The diagram must be in the Mermaid format:

https://github.com/mermaid-js/mermaid.

• The diagram must show a clear distinction between the products in the

data ingestion subsystem and the serving subsystem.

• The diagram must show Managed Service for Apache Spark as a shared

component, bridging the data ingestion and serving subsystems.

• [ ] Step 4: Generate design recommendations: Generate design guidance

based on the guidelines in references/design_recommendations.md.

• [ ] Step 5: Draft solution architecture: Compile the requirements,

technical decomposition, product mapping, architecture diagram, and design recommendations into a single Markdown file named solution-architecture-guide.md, based on the template in assets/output-template.md.

• [ ] Step 6: Request review: Present the generated solution architecture to

the user and request their feedback or approval.

• [ ] Step 7: Iterate: If the user requests changes, generate an updated

solution architecture and repeat steps 2-6 until the user approves the solution architecture.

Phase 3: Implementation plan

• [ ] Step 1: Retrieve relevant implementation resources:
• Build a Multicloud Open Data Lakehouse with Agentic AI
• Terraform Registry documentation for biglake_iceberg_catalog
• Create an Apache Iceberg table with metadata in Lakehouse runtime catalog
• Accelerate Spark batch workloads and sessions with Lightning Engine
• Create data agents

Important: Use these resources as the technical foundation for the IaC and deployment instructions you generate in the remaining steps of this phase.

• [ ] Step 2: Identify deployment prerequisites: Document prerequisites for

the deployment, including the following:

• Projects and billing associations
• Required Google Cloud APIs
• Required IAM permissions
• Any other prerequisites

• [ ] Step 3: Generate Infrastructure as Code (IaC): Generate code (e.g.,

Terraform) and deployment scripts to automate the provisioning of the proposed Google Cloud resources.

• [ ] Step 4: Write deployment instructions: Draft sequential, step-by-step

deployment instructions to execute the IaC and initialize the workload components.

• [ ] Step 5: Request review: Present the generated deployment instructions

to the user for feedback and confirmation.

• [ ] Step 6: Iterate: If the user requests changes, generate an updated

implementation plan and repeat steps 2-5 until the user approves the implementation plan.

Phase 4: Solution validation

• [ ] Step 1: Retrieve relevant verification resources (optional): If the

resources from Phase 3 are not already in your context, retrieve the same implementation resources as the starting point for the validation checks and verification scripts that you generate in this phase.

• [ ] Step 2: Define validation checks: Outline validation steps to verify

that the deployed infrastructure meets the workload requirements:

• Deployment dry-run: Commands like terraform plan to preview

changes.

• Connectivity and routing: Verification of network paths, load

balancer routing, and service endpoints.

• Security policies: Verification of restricted access, firewall

rules, and IAM enforcement.

• [ ] Step 3: Generate verification scripts: Draft lightweight scripts or

command-line instructions (e.g. using curl or gcloud) that the user can run to perform these validation checks.

• [ ] Step 4: Compile validation report: Document the validation steps,

verification scripts, and expected outcomes in a single Markdown file.

• [ ] Step 5: Conduct validation and finalize: Assist the user in executing

the validation checks and troubleshooting any deployment issues. After the solution is validated successfully, request final approval from the user.

• [ ] Step 6: Iterate: If the user requests changes, then generate an

updated validation plan and repeat steps 2-5 until the user approves the validation plan.
