🎯 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):

variable "deploy_langfuse" { default = true }
variable "deploy_mcp_gateway" { default = true }
variable "deploy_lambda_code_interpreter" { default = true }

After (mcp-gateway-registry):

# 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

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

cd terraform/aws-ecs/
terraform init
terraform validate

Expected: "Success! The configuration is valid."

3. Check Documentation

cat terraform/aws-ecs/README.md
cat terraform/DEPLOYMENT_GUIDE.md
cat DEPLOYMENT_STEPS.md

Expected: Complete, readable documentation

4. Verify No Breaking Changes

# 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:

# 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:

# Edit Terraform
vim terraform/aws-ecs/main.tf

# Review changes
terraform plan

# Apply changes
terraform apply
