Michele Adduci explains how Gematik transformed the DEMIS disease monitoring platform from manual deployments every 3 weeks to automated CD with multiple weekly deployments in just 10 minutes. The infrastructure-as-code approach with Terraform, Kubernetes, and Istio enabled a zero-drift policy while supporting the COVID-19 pandemic response at scale.

The article demonstrates how to deploy self-hosted GitLab runners on Kubernetes clusters using Helm, enabling teams to run CI/CD pipelines with auto-scaling infrastructure while maintaining full control over the build environment. This approach provides equivalent functionality to Jenkins Kubernetes agents, with the advantage of GitLab's unified DevOps platform.

Julius Omoleye demonstrates managing 100-plus infrastructure components with Terragrunt's cascading configuration hierarchy that eliminates duplication through DRY principles. The approach enables bulk operations across multiple products, environments, and regions while maintaining predictable and maintainable infrastructure code at enterprise scale.

Pierrick Gicquelais details Alan's 21-day migration of 200-plus Terraform resources from Cloudflare provider v4 to v5, requiring 969 Terraform commands and 258 resource imports. The Terramate orchestrator enabled incremental, stack-by-stack migrations while AI assistance with Claude accelerated script generation for this complex provider upgrade.
