The stack worked — technically — but it came at a cost:

The Infra Tangle: When “Multicloud” Becomes Multi-Mess

Our customer was stuck in the middle of that triangle.

They had:

The Terraform codebase reflected that chaos. Every cloud had its own set of conditions, variables, and exceptions, crammed into a single spaghetti-like repository. It took ages to run, was hard to debug, and nearly impossible to upgrade safely.

Step 1: Costs First, Then Cleanup

Next, we tackled cloud consolidation.

Step 2: Rancher + AKS, Not Multicloud Kubernetes

We standardised Kubernetes across all environments — but without trying to run a true multicloud cluster.

This “split but unified” approach gave us the best of both worlds:

Step 3: Load Balancers, WAF, and Vendor Lock Workarounds

It worked — until it didn’t.

This turned out to be the best combo:

Step 4: Modular Terraform FTW

The most underrated improvement?

We took the monolithic Terraform codebase and:

That made the entire system:
