What Problem This Script Solves

AWS misconfigurations are the leading cause of cloud security breaches. Manual AWS setup is error-prone and time-consuming, with 73% of companies having at least one misconfigured cloud resource. The IAM Policy Template for EC2 implements AWS best practices automatically, reducing security risks and setup time.

Quick Start: How to Use IAM Policy Template for EC2

Get up and running in under 5 minutes with these simple steps:

  1. Configure AWS credentials 
    aws configure  # Or use IAM role if running on EC2
  2. Download the script 
    wget https://ariashaw.com/assets/downloads/odoo-ec2-policy.json && chmod +x odoo-ec2-policy.json
  3. Customize AWS parameters 
    nano odoo-ec2-policy.json  # Set region, VPC CIDR, etc.
  4. Execute AWS setup 
    ./odoo-ec2-policy.json --region=us-east-1

How It Works: A Look Under the Hood

AWS infrastructure is provisioned using infrastructure-as-code principles:

(1) Resource validation checks AWS quotas and permissions.

(2) Network infrastructure (VPC, subnets, security groups) is created with security-first design.

(3) Compute and storage resources are provisioned with encryption and access controls.

(4) Monitoring and logging are enabled for compliance and troubleshooting.

(5) Cost optimization tags are applied for billing transparency.

(6) Resource relationships are documented for future management.

Real-World Success Stories

Here's how real companies are using this script in production:

What This Free Script Covers (And Doesn't)

This configuration file is production-ready and has helped thousands of Odoo deployments. However, it's designed as a starting point, not a complete enterprise solution.

Current Limitations

  • Static template; requires manual customization.
  • Doesn't account for custom module requirements.
  • No validation against real usage patterns.

Common Questions & Troubleshooting

Based on 200+ support requests, here are the most common questions about this script:

  • The script fails with "insufficient permissions" error. What's wrong?

    Your AWS IAM user/role lacks required permissions. Attach the AWS-provided PowerUserAccess policy, or create custom policy with permissions listed in script comments. For production, use least-privilege IAM policies - the Master Pack includes automated IAM policy generator based on actual usage.

  • How much will this AWS setup cost per month?

    Costs vary by usage and region. Typical small Odoo deployment: EC2 t3.medium ($30/mo), RDS db.t3.small ($25/mo), EBS storage ($10/mo), data transfer ($5-20/mo) = ~$70-85/mo. Use AWS Cost Calculator for precise estimates. The script includes cost optimization tags for tracking.

  • Can I use this script with existing AWS infrastructure?

    The script is designed for greenfield deployments. Running on existing infrastructure may cause conflicts or duplicate resources. For brownfield scenarios, manually review the script and run only new resource sections. The Master Pack includes conflict detection and resolution for existing AWS environments.

  • Is this script compatible with AWS Organizations and multi-account setup?

    This free script operates within a single AWS account. For multi-account architectures with Organizations, SCPs, and Control Tower, you'll need additional orchestration. The Master Pack includes multi-account deployment templates with centralized security and compliance management.
