# Required tools
- AWS Account with programmatic access
- Terraform >= 1.0
- AWS CLI >= 2.0
- Git >= 2.0
- SSH key pair for EC2 accessBefore deploying the main infrastructure, set up the Terraform backend:
# 1. Clone the repository
git clone https://github.com/Analo/aws-scalable-ecommerce-platform.git
cd aws-scalable-ecommerce-platform
# 2. Setup Terraform backend (run once)
./scripts/setup-backend.sh
# 3. The script will create:
# ✅ S3 bucket for state storage with encryption
# ✅ DynamoDB table for state locking
# ✅ Backend configuration file
# 4. Outputs will show your backend configuration🔐 Why Centralized State Management?
- 🔒 State Locking: Prevents concurrent modifications and conflicts
- 👥 Team Collaboration: Enables multiple developers to work safely
- 📦 Centralized Storage: Single source of truth for infrastructure state
- 🔄 Version History: Complete state file versioning and recovery
- 🛡️ Security: Encrypted storage with fine-grained access controls
# 1. Configure environment variables
cp terraform/terraform.tfvars.example terraform/terraform.tfvars
# Edit terraform.tfvars with your settings
# 2. Deploy infrastructure
./scripts/deploy.sh
# 3. Monitor deployment progress
./scripts/health-check.sh
# 4. Access your application
echo "🚀 Application URL: $(terraform output -raw application_url)"# Run comprehensive tests
./scripts/run-tests.sh
# Load testing
./scripts/load-test.sh
# Security validation
./scripts/security-scan.sh
# Cost analysis
./scripts/cost-analysis.shaws-scalable-ecommerce-platform/
