Multi-Cloud Infrastructure as Code with Terraform and GitOps

Overview

 An enterprise client operating in AWS, GCP, and Azure needed a unified infrastructure approach. We helped them consolidate provisioning, standardize configurations, and reduce infrastructure drift — all through Terraform and GitOps workflows.

The Challenge

Slow, manual provisioning across clouds

Inconsistent environments across teams

Lack of audit trails and change history

Our Solution

 We used:

  • Terraform + Terragrunt for reusable, DRY configurations
  • GitHub Actions + Atlantis for plan/apply workflows
  • Centralized backends (S3 + DynamoDB) for state management
  • Fine-grained IAM to avoid permission conflicts

Deployment Strategy

One modular Terraform codebase across clouds

Pull-request driven infra changes

Git-based tracking for full auditability

Automated plan approvals for safer changes

Key Hurdles & How We Solved Them

Multi-cloud complexity
Used Terragrunt for abstraction and DRYness
State conflicts
Managed with robust remote state backends
Role misconfigurations
Applied strict IAM boundaries per team/cloud

Results We achieve

Provisioning time cut by 80%
100% consistency across cloud accounts
Infrastructure governance improved significantly

Conclusion

Our Infrastructure as Code approach gave the client full control and visibility across all cloud platforms — at enterprise scale.
