+### 2. Documentation
+- **terraform/aws-ecs/README.md** - AWS ECS deployment guide (250+ lines)
+- **terraform/DEPLOYMENT_GUIDE.md** - Complete deployment options (300+ lines)
+- **terraform/INTEGRATION_SUMMARY.md** - Technical integration details
+- **DEPLOYMENT_STEPS.md** - Step-by-step deployment instructions (400+ lines)
+
+### 3. Updated Main README
+- Added "Production Deployment" section
+- Added AWS ECS Terraform deployment instructions
+- Added link to deployment guide
+
+---
+
+## 🎯 Why These Changes Were Made
+
+### Problem Solved
+**Before:** Users had no clear path from local development to production AWS deployment
+
+**After:** Users have three deployment options with clear documentation:
+1. Local Docker Compose (development)
+2. AWS EC2 (small production)
+3. AWS ECS Fargate (enterprise production)
+
+### Key Benefits
+
+#### 1. **Single Source of Truth**
+- Code and infrastructure in one repository
+- Atomic versioning (git tag covers both)
+- Simplified CI/CD
+
+#### 2. **Clear Deployment Path**
+- Progression: Local → EC2 → ECS
+- Same application code everywhere
+- Infrastructure-as-code for all environments
+
+#### 3. **Production-Ready**
+- Multi-AZ high availability
+- Auto-scaling (2-4 tasks)
+- CloudWatch monitoring (11 alarms)
+- HTTPS support with ACM
+- Managed database (Aurora Serverless v2)
+
+#### 4. **Better User Experience**
+- No confusion about deployment options
+- Clear cost estimates
+- Comprehensive documentation
+- Troubleshooting guides
+
+---
+
+## 🔄 What Changed from agent-framework-tf
+
+### Simplified Configuration
+**Removed:**
+- Langfuse module (separate concern)
+- Lambda code interpreter (separate concern)
+- Conditional deployment flags
+
+**Kept:**
+- MCP Gateway module (unchanged)
+- VPC configuration (unchanged)
+- ECS cluster (unchanged)
+- All production features
+
+**Result:** Focused, simpler deployment for MCP Gateway only
+
+### Updated Variables
+**Before (agent-framework-tf):**
+```hcl
+variable "deploy_langfuse" { default = true }
+variable "deploy_mcp_gateway" { default = true }
+variable "deploy_lambda_code_interpreter" { default = true }
+```
+
+**After (mcp-gateway-registry):**
+```hcl
+# Removed - MCP Gateway always deployed
+# Simplified to essential variables only
+variable "name" { default = "mcp-gateway" }
+variable "aws_region" { default = "us-east-1" }
+variable "vpc_cidr" { default = "10.0.0.0/16" }
+```
+
+### Updated Outputs
+**Before:** Conditional outputs for 3 components
+**After:** Direct outputs for MCP Gateway only

+
+## ✅ Verification Steps
+
+### 1. Verify Directory Structure
+```bash
+cd /Users/aviyadc/Repository/genai-engagements/mcp-gateway-registry
+ls -la terraform/aws-ecs/
+```
+
+**Expected:** main.tf, variables.tf, outputs.tf, vpc.tf, ecs.tf, modules/
+
+### 2. Validate Terraform
+```bash
+cd terraform/aws-ecs/
+terraform init
+terraform validate
+```
+
+**Expected:** "Success! The configuration is valid."
+
+### 3. Check Documentation
+```bash
+cat terraform/aws-ecs/README.md
+cat terraform/DEPLOYMENT_GUIDE.md
+cat DEPLOYMENT_STEPS.md
+```
+
+**Expected:** Complete, readable documentation
+
+### 4. Verify No Breaking Changes
+```bash
+# Existing Docker Compose should still work
+./build_and_run.sh --prebuilt
+```
+
+**Expected:** Services start normally
+
+---
+
+## 🎓 For Developers
+
+### Understanding the Integration
+
+**Relationship:**
+```
+mcp-gateway-registry (Application Code)
+         ↓
+    Docker Images
+         ↓
+terraform/aws-ecs/ (Infrastructure)
+         ↓
+    AWS ECS Deployment
+```
+
+**Key Principle:** Application code is environment-agnostic. Terraform deploys it to AWS.
+
+### Making Changes
+
+**To update application:**
+```bash
+# Edit application code
+vim registry/main.py
+
+# Test locally
+./build_and_run.sh
+
+# Deploy to AWS (uses new image)
+cd terraform/aws-ecs/
+terraform apply
+```
+
+**To update infrastructure:**
+```bash
+# Edit Terraform
+vim terraform/aws-ecs/main.tf
+
+# Review changes
+terraform plan
+
+# Apply changes
+terraform apply
+```
