Terraform IaC & Cloud State Automation
Declarative, reproducible cloud infrastructure engineering. Remote S3 backend state management with DynamoDB distributed locking, modular AWS blueprints, and automated Checkov security compliance.
Remote S3 State + DynamoDB Locks
Checkov & tfsec Security Scans
Modular Multi-AZ VPC Blueprints
Automated State Drift Detection
1. Production Remote State Backend with Mutex Locking
Preventing Concurrent Apply Conflicts & State Corruption
Tested backend configuration engineered by Ajit Dev with server-side KMS encryption and DynamoDB distributed state locking:
# backend.tf — Production Hardened State Storage
terraform {
required_version = ">= 1.6.0"
backend "s3" {
bucket = "ajitdev-prod-terraform-state-vault"
key = "production/infrastructure.tfstate"
region = "us-east-1"
encrypt = true
dynamodb_table = "ajitdev-prod-terraform-locks"
}
required_providers {
aws = {
source = "hashicorp/aws"
version = "~> 5.0"
}
}
}
2. Reusable Infrastructure Modules
Parameterized Declarative Cloud Resources
Extract of a production Terraform module provisioning an isolated 3-tier VPC with managed NAT Gateways:
# modules/vpc/main.tf — Declarative Subnets
module "vpc" {
source = "terraform-aws-modules/vpc/aws"
version = "5.5.0"
name = "ajitdev-production-vpc"
cidr = "10.0.0.0/16"
azs = ["us-east-1a", "us-east-1b"]
public_subnets = ["10.0.1.0/24", "10.0.2.0/24"]
private_subnets = ["10.0.10.0/24", "10.0.11.0/24"]
database_subnets = ["10.0.20.0/24", "10.0.21.0/24"]
enable_nat_gateway = true
single_nat_gateway = false # Multi-AZ High Availability
enable_dns_hostnames = true
enable_dns_support = true
