Version 1.1.0 (2026-Q2)

Cost Estimation

New built-in cost estimation feature for S3 infrastructure. Calculate monthly and annual costs before deployment with region-specific pricing from the AWS Pricing API.

New Actions

  1. cost-traffic — Generate an editable usage assumptions file with default monthly values for storage, requests, data transfer, and VPC Endpoint traffic

  2. cost-estimate — Calculate a detailed cost breakdown with storage, request, transfer, and VPC Endpoint costs. Generates a professional HTML report

  3. cost-refresh-prices — Refresh the built-in pricing data from the AWS Pricing API across all standard AWS regions

Cost Estimation Features

  • Region-specific on-demand pricing for S3 storage, requests, data transfer, and VPC Endpoints

  • Pre-loaded pricing data ships with the Docker image (works offline)

  • Editable usage assumptions for scenario modeling

  • Professional HTML cost reports

  • Fallback to hardcoded rates if pricing data is unavailable

Version 1.0.0 (2026-04-01)

Initial Release

First production release of S3 Provisioner.

Core Features

Bucket Provisioning

  • Create S3 buckets via CloudFormation

  • Configure versioning (enabled/disabled)

  • Configure tags (system + custom)

  • VPC endpoint support

  • Automated bucket naming or custom override

Automated Lifecycle Policy Profiles

4 automated lifecycle policy profiles for ML workloads with cost optimization:

lifecycle_policy Configuration:

s3:
  lifecycle_policy: ml-optimized  # or compliance, development, none

Available Profiles:

  1. ml-optimized - Production ML workloads

    • Transitions: STANDARD → STANDARD_IA (30 days) → GLACIER (90 days)

    • Expiration: None (data retained indefinitely)

    • Cost savings: ~60-70%

    • Use case: Active ML pipelines with long-term data retention

  2. compliance - HIPAA/PCI regulated industries

    • Transitions: STANDARD → GLACIER (90 days)

    • Expiration: 2555 days (7 years)

    • Cost savings: ~70-80%

    • Use case: Regulated data with mandatory retention periods

  3. development - Dev/staging environments

    • Transitions: None

    • Expiration: 90 days

    • Cost savings: ~100% (data deleted after 90 days)

    • Use case: Temporary development/testing data

  4. none - No lifecycle rules (default)

    • Transitions: None

    • Expiration: None

    • Use case: Manual lifecycle management

Implementation:

  • Lifecycle rules automatically added to CloudFormation templates

  • Rules apply to solutions/ prefix

  • Default behavior: lifecycle_policy defaults to ‘none’ (no lifecycle rules)

Configuration Management

  • YAML-based configuration (client, environment, s3 sections)

  • Schema validation

  • IAM policy generation

  • CloudFormation template generation

Solution Deployment

  • Master solution folder structure

  • ML-optimized folder hierarchy (data/raw, curated, processed, inference)

  • Multiple solution support (customer-churn, demand-forecasting, fraud-detection)

  • Folder cloning from master template

GitKeep Management

  • Full .gitkeep file creation

  • Selective .gitkeep removal

  • Bucket-wide .gitkeep purge

Supported Actions (19)

  1. validate-config - Validate YAML against schema

  2. create-policy - Generate IAM policy JSON

  3. create-prov-template - Generate CloudFormation template

  4. validate-prov-template - Validate generated template locally (no AWS calls)

  5. show-changes - Preview pending changes via CloudFormation ChangeSet

  6. check-drift - Detect infrastructure drift against deployed stack

  7. test-deploy - Deploy with isolated test suffix for safe testing

  8. create-bucket - Create S3 bucket via CloudFormation (requires --force)

  9. prep-master - Prepare master solution structure (requires --force)

  10. deploy-solution - Deploy ML solution folders
