Deploying Multi-Cloud Infrastructure with Terraform Modules

Day 15 of my Terraform journey was about moving from basic provider usage into more advanced provider patterns. This was the day where Terraform started to feel much more like a real infrastructure orchestration tool rather than just a way to create isolated cloud resources. The main focus was learning how to: build modules that accept provider configurations from their callers use multiple providers in one Terraform project manage Docker locally with Terraform prepare an AWS EKS + Kubernetes deployment using Terraform GitHub reference: 👉 Github Link Why This Topic Matters In real infrastructure, one provider configuration is often not enough. You may need: one AWS region for primary infrastructure another AWS region for replicas a separate AWS account for production Kubernetes to deploy workloads after AWS creates the cluster Docker locally for quick testing before cloud deployment That means the real question is no longer just: “How do I use a provider?” It becomes: “How do I pass t
