Infrastructure as Code (IaC) berarti mendefinisikan dan mengelola infrastruktur Anda (server, jaringan, database) melalui file kode/konfigurasi daripada setup manual. Tool seperti CloudFormation, Terraform, dan CDK membuat infrastruktur dapat diulang, terkontrol versi, dan otomatis.
Masalah yang IaC selesaikan
MANUALLY setting up infrastructure (clicking in the Console) is:
→ not REPEATABLE (hard to recreate identically; error-prone)
→ not VERSIONED (no history of what changed, by whom, why)
→ not DOCUMENTED (the setup lives only in someone's memory/clicks)
→ hard to review, share, or roll back
→ IaC defines infrastructure in CODE → solving all of this.
