S3 Lifecycle to Intelligent-Tiering

📦 Overview

This Terraform module applies a lifecycle rule to an existing Amazon S3 bucket, automatically transitioning objects to the INTELLIGENT_TIERING storage class after 30 days.

It’s ideal for production or archive environments where access patterns are unpredictable and manual tiering is inefficient.

---

✅ Key Features

• Automatically transitions S3 objects to INTELLIGENT_TIERING after 30 days
• Reduces costs while maintaining high availability and low latency
• Adapts to shifting access patterns without user intervention
• Supports tagging and is reusable across environments

---

💼 Use Cases

• Data lakes with variable or unknown access patterns
• Long-term logs, backups, or exports with inconsistent access
• Secure buckets needing smarter storage management
• Cost-conscious workloads that require availability but not tiering oversight

---

📥 Input Variables

Name	Type	Description
region	string	AWS region where the target S3 bucket exists
bucket_name	string	Name of the S3 bucket to apply the lifecycle rule to
transition_days	number	Number of days before transitioning objects to INTELLIGENT_TIERING
environment	string	Tag to specify the deployment environment (e.g., dev, staging, prod)

---

📤 Outputs

Name	Description
bucket_name	The name of the S3 bucket with the lifecycle rule
rule_id	The ID of the lifecycle rule applied

---

🚀 Deployment Readiness

• ✅ Compatible with Terraform 1.0+
• ✅ Tested with AWS provider 5.x
• 🧪 Requires an existing S3 bucket and permissions to apply lifecycle policies

🛠️ Example Usage

module "s3_lifecycle_intelligent_tiering" {
  source          = "git::ssh://git@github.com/archiphire/aws-level-1-modules.git//storage/s3-lifecycle-intelligent-tiering?ref=v1.0.0"

  region          = "us-east-1"
  bucket_name     = "archiphire-prod-data"
  transition_days = 30
  environment     = "prod"
}

terraform init
terraform plan
terraform apply

or

tofu init
tofu plan
tofu apply

🧹 Cleanup Options

Terraform Destroy (for test environments):

terraform destroy

or

tofu destroy

⚠️ This only removes the lifecycle rule. Your S3 bucket and its contents will remain unaffected unless manually deleted.
