Google Cloud Foundations

Before technical deployment, you must align the cloud structure with the business's legal, financial, and technical requirements.

• Define the Resource Hierarchy (Organization, Folders, and Project naming conventions).

• Map business cost centers to Cloud Billing Accounts.

• Identify data residency requirements to determine Regional Restrictions.

Establish a "Single Source of Truth" for users and define the boundaries of who can do what by integrating existing identity providers and establishing the Principle of Least Privilege.

• Sync Google Cloud Directory Sync (GCDS) or set up SSO/SAML with Azure AD or Okta.

• Establish Super Admin and Organization Admin break-glass accounts.

• Define Custom Roles and IAM groups to avoid assigning permissions to individuals.

Create a scalable container system that allows for inherited policies and organized management.

• Create a Common Folder for shared services (logging, networking, monitoring).

• Establish Environment Folders (Prod, Non-Prod, Development).

• Apply IAM bindings at the folder level to automate permission inheritance.

Centralize network management to ensure security while allowing application teams to move fast by designing a secure, scalable network architecture using Google’s "Shared VPC" best practices.

• Provision a Host Project to manage centralized networking.

• Configure Shared VPCs and subnets across regions.

• Set up Cloud Interconnect or Cloud VPN for secure on-premises connectivity.

• Establish Cloud DNS peering and private service access.

Implement proactive "fences" that prevent insecure configurations before they happen by enforcing corporate governance across the entire organization using Google’s Policy Service.

• Enable Organization Policy Constraints (e.g., "Restrict Public IP access," "Limit Resource Usage to specific regions").

• Configure VPC Service Controls (VPC-SC) to create a security perimeter around sensitive data.

• Set up Cloud KMS (Key Management Service) for centralized encryption control.

Ensure that every action in the cloud is recorded, searchable, and alerted upon by building a "Single Pane of Glass" for security and operational monitoring.

• Create an Aggregated Log Sink to export all Audit Logs to a central Security Project.

• Configure BigQuery or Pub/Sub as destinations for long-term log retention and SIEM integration.

• Build baseline Cloud Monitoring Dashboards and Uptime Checks.

   

Establish financial transparency and prevent "bill shock" through automated reporting by sSetting up the tools required for FinOps and cost accountability.

• Configure Billing Export to BigQuery for granular cost analysis.

• Set up Budget Alerts at the Project and Folder levels.

• Implement a Tagging/Labeling Policy to track spend by department or application.

Transition from manual "Point-and-Click" setup to a repeatable, version-controlled codebase by automating the Landing Zone deployment using industry-standard tools like Terraform.

• Build a Terraform Seed Project with a Cloud Build pipeline.

• Deploy Infrastructure-as-Code modules for Projects, VPCs, and IAM.

• Store state files in a secure, encrypted Cloud Storage Bucket.

Create a repeatable process for internal teams to "buy" new, compliant cloud environments by formalizing the transition from "Setup" to "Operations."

• Develop a Project Vending Machine script to automate compliant project creation.

• Conduct a Security Review and "Well-Architected" assessment.

• Deliver Operational Runbooks and train the customer's IT team on the new foundation.
