Terraform Multi-Cloud Migration

A modernization program focused on standardizing environment delivery across AWS and GCP with reusable Terraform patterns and automated rollout workflows.

2Clouds standardized - AWS and GCP delivered through one IaC approach

~70%Manual provisioning reduced - sanitized estimate after Terraform adoption

days to hoursDeployment prep time - for repeat environment creation

50+ resourcesReusable module coverage - managed through versioned Terraform patterns

Challenge

The migration needed to reduce manual environment setup while keeping multi-cloud delivery consistent, reviewable, and low risk for the operating team.

Architecture snapshot

Reusable Terraform modules for shared platform primitives
Environment-specific configuration for AWS and GCP workloads
Versioned deployment workflow with review checkpoints
Automated rollout path replacing one-off manual provisioning

Implementation approach

Consolidated infrastructure decisions into reusable Terraform building blocks rather than environment-by-environment manual setup.
Aligned deployment automation with reviewable plans so teams could ship infrastructure changes with clearer rollback and approval paths.
Used repeatable migration sequencing to move workloads without creating cloud-specific drift.
