Case Study - Multi-Cloud Governance with Luce

Executive Summary

In October 2026, We implemented a multi-cloud governance solution for a financial services organization managing complex AWS/GCP hybrid infrastructure. The project leveraged Terraform, OpenTofu, and automated governance tools to achieve a meaningful cost reduction and 100% compliance automation, establishing a scalable framework for multi-cloud operations.

The Challenge: Managing AWS/GCP Hybrid Setups

The financial services organization faced significant challenges with their multi-cloud infrastructure:

Governance Complexity

• Multi-Cloud Sprawl: 200+ resources across AWS and GCP with inconsistent management
• Compliance Gaps: Regulatory requirements for financial data across multiple clouds
• Cost Visibility: Limited transparency into cross-cloud spending and resource utilization
• Security Fragmentation: Different security policies and controls across cloud providers
• Operational Silos: Separate teams and processes for each cloud platform

Business Impact

• Compliance Risk: Regulatory violations due to incomplete governance
• Cost Overruns: 30% higher infrastructure costs due to lack of optimization
• Operational Inefficiency: Manual processes for cross-cloud management
• Security Vulnerabilities: Inconsistent security controls across platforms
• Audit Challenges: Complex audit trails across multiple cloud providers

Technical Constraints

• Infrastructure Drift: Manual changes causing configuration inconsistencies
• Data Lineage: Limited visibility into data flow across cloud boundaries
• Access Control: Different IAM systems and permission models
• Monitoring Fragmentation: Separate monitoring and alerting systems
• Backup Complexity: Different backup strategies and retention policies

Solution: Unified Multi-Cloud Governance

We implemented a multi-cloud governance solution using modern infrastructure and governance technologies:

Technical Stack

• Terraform Multi-Cloud: Infrastructure as Code across AWS and GCP
• OpenMetadata: Unified data governance and lineage tracking
• Crossplane: Multi-cloud resource orchestration
• HashiCorp Vault: Centralized secrets management
• Grafana: Unified monitoring and observability
• Kubernetes: Container orchestration across clouds

Multi-Cloud Architecture

Our multi-cloud governance architecture follows a unified approach with centralized management, consistent policies, and complete traceability across cloud providers while maintaining security and compliance standards.
