🏗️ Infrastructure as Code (IaC) nima?

Infratuzilmani kod orqali boshqarish. Afzalliklari: versioning (Git), repeatability, automation, drift detection. Deklarativ (Terraform, Pulumi) vs Imperativ (Ansible, scripts). Terraform — deklarativ: "Nima kerak" ni yozasiz, Terraform "Qanday" qilishni biladi.

⚔️ Terraform vs Alternativlar

Terraform — cloud-agnostic, HCL, state management, 3000+ providers. AWS CloudFormation — faqat AWS, JSON/YAML. Pulumi — real programming languages (Python, TS). Ansible — configuration management + IaC. CDK — AWS-specific, programming languages.

🌐 Terraform Use Cases

Multi-cloud infrastructure provisioning. Application infrastructure (VPC, EC2, RDS). Kubernetes cluster yaratish. DNS va CDN boshqarish. SaaS provider (GitHub, Datadog) boshqarish.

📊 IaC Toollar Taqqoslash

Tool	Yondashuv	Til	Cloud Support	Asosiy Use Case
Terraform	Declarative	HCL	Multi-cloud	Infrastructure provisioning
AWS CloudFormation	Declarative	JSON/YAML	AWS only	AWS-native IaC
Pulumi	Declarative	Python/TS/Go	Multi-cloud	Programmers prefer code
Ansible	Imperative	YAML	Multi-cloud	Config management + IaC
AWS CDK	Declarative	Python/TS/Java	AWS only	Developers, generates CFn

💡 Asosiy nuqtalar

IaC: infratuzilma kod sifatida (versionlash, avtomatlashtirish)
Terraform: deklarativ, cloud-agnostic
HCL (HashiCorp Configuration Language)
3000+ providers: AWS, GCP, Azure, GitHub...
State file: real infratuzilma holati

🎯 Imtihon maslahatlari

Deklarativ = "Nima kerak" (desired state). Imperativ = "Qanday qilish" (step-by-step commands)
Terraform "drift detection": real infra va state farq qilsa `plan` ko'rsatadi
HCL — HashiCorp Configuration Language, JSON ga o'xshash lekin odam o'qiy oladigan
Terraform Cloud vs Terraform Enterprise: Cloud = SaaS, Enterprise = self-hosted
Open Tofu — Terraform open-source fork (BSL license o'zgarishidan keyin)

⚠️ Ko'p adashadigan

Ansible = Terraform deb o'ylash: Ansible configuration management, Terraform infrastructure provisioning
Pulumi imperativ deb o'ylash: Pulumi programming language ishlatsa ham deklarativ desired state model
CloudFormation Terraform dan kuchli deb o'ylash — CloudFormation faqat AWS, Terraform multi-cloud

🧠 Eslab qolish: "Terraform = Tell what, not how" — deklarativ. "HCAP" = HashiCorp Configuration (HCL), cloud-Agnostic, 3000+ Providers
