Remote State & Modular TaskFlow Infrastructure
Build production-ready Terraform! Configure remote state with S3 backend for team collaboration, create reusable modules for VPC/EC2/S3/IAM/RDS, and compose modular infrastructure following professional patterns. Deploy the real TaskFlow app and verify it over HTTP, all from one terraform apply.
Lab Overview
Level up your Terraform skills with remote state management and modular infrastructure patterns. Configure S3 backend for team collaboration with native state locking, and create reusable Terraform modules for VPC, EC2, S3, IAM, and RDS components.
You'll transform your monolithic Terraform code from Lab 1 into professional, modular infrastructure that's ready for team workflows, then go further than most modules labs do: wire a real IAM instance profile, render a real deployment script with templatefile(), and bring the actual TaskFlow application online, verified over HTTP, from a single terraform apply.
What You'll Learn
