Production-Grade Platforms: Real-World IaC Practices on AWS

What this session is about

Managing infrastructure as code sounds straightforward until you're wrangling hundreds of modules across multiple teams and accounts. In this session, a Platform Engineer and Lead Architect share hard-won lessons from building and scaling IaC platforms at large organisations — covering module composition strategies, state isolation patterns, and CI/CD pipelines that keep deployments safe and reproducible. You'll walk away with practical design patterns you can apply immediately, whether you're laying the foundations of your first landing zone or untangling a sprawling estate that's grown faster than its architecture.

Editorial commentary · what to actually do about this on Monday

The concept
Real-world IaC at scale. Module composition strategies, state isolation patterns, CI/CD pipelines for safe and reproducible deployments.
Why it matters
IaC fragility is a top cause of outages at scale. The patterns that work for one team don't work at multi-team scale.
The hard parts
State management in Terraform/CDK. Drift detection. Module composition without circular dependencies.
Playbook moves
(1) State per environment, not per service. (2) Drift detection in CI. (3) Composition over inheritance for modules.
The surprise
The hardest IaC problem isn't writing it — it's *deleting* it. Resources orphaned by failed deploys are an iceberg of cost and risk. Audit and clean regularly; most orgs accumulate orphans for years before noticing. ---
