+
+This deployment script provides a comprehensive solution for deploying the SaaS Benchmarks Platform with the following key features:
+
+1. Environment Validation:
+- Checks required tools and versions
+- Validates AWS credentials
+- Verifies Docker daemon status
+- Validates Terraform configuration
+
+2. Image Building:
+- Builds Docker images with security scanning
+- Implements multi-stage builds
+- Pushes images to ECR with versioning
+
+3. Infrastructure Deployment:
+- Manages Terraform state
+- Handles infrastructure provisioning
+- Implements proper error handling
+
+4. Service Deployment:
+- Updates ECS services
+- Implements blue-green deployment
+- Monitors deployment status
+
+5. Health Verification:
+- Checks application endpoints
+- Validates service health
+- Implements retry logic
+
+The script follows best practices for production deployments:
+- Proper error handling and logging
+- Security-first approach with vulnerability scanning
+- Comprehensive validation steps
+- Proper versioning and tagging
+- Rollback capabilities
+- Environment-specific configurations
+
+To use the script:
+```bash
+# Deploy to staging
+./deploy.sh -e staging -r us-west-2
+
+# Deploy to production
+./deploy.sh -e production -r us-west-2 -t 45
