## 📋 Project Overview
**XYZ Corporation VPC Architecture & Network Isolation Solution** - A comprehensive AWS networking implementation demonstrating multi-tier architecture design, VPC peering, and enterprise-grade security for production and development environments.
### 🎯 Key Achievements
- ✅ **4-Tier Production Architecture** - Web, App, Cache, and Database layers
- ✅ **2-Tier Development Architecture** - Simplified web and database setup
- ✅ **Secure Network Isolation** - Private subnets with controlled internet access
- ✅ **VPC Peering Integration** - Cross-environment database connectivity
- ✅ **Enterprise Security** - Multi-layered security groups and NACLs
- ✅ **Cost-Effective Design** - Optimized NAT Gateway usage
## 🔗 Infrastructure as Code Collection [Pending]
> **📋 Complete Automation Scripts**: [GitHub Gists Collection](https://gist.github.com/himanshu2604/vpc-automation-collection)
While this case study demonstrates hands-on AWS Console implementation for learning purposes, I've also created production-ready automation scripts that achieve the same results programmatically:
| Script | Purpose | Gist Link |
|--------|---------|----------|
| 🏗️ **Production VPC Setup** | 4-tier VPC with 5 subnets | [View Script](https://gist.github.com/himanshu2604/production-vpc-automation) |
| 💻 **Development VPC Setup** | 2-tier VPC configuration | [View Script](https://gist.github.com/himanshu2604/development-vpc-automation) |
| 🔗 **VPC Peering Automation** | Cross-VPC connectivity | [View Script](https://gist.github.com/himanshu2604/vpc-peering-automation) |
| 🔒 **Security Groups Setup** | Multi-tier security rules | [View Script](https://gist.github.com/himanshu2604/security-groups-automation) |
| 🚀 **EC2 Instance Deployment** | Automated instance launch | [View Script](https://gist.github.com/himanshu2604/ec2-deployment-automation) |
**Why Both Approaches?**
- **Manual Implementation** (This Repo) → Understanding AWS VPC services deeply
- **Automated Scripts** (Gists) → Production-ready Infrastructure as Code
## 🏗️ Problem Statement
**Challenge**: XYZ Corporation required separate, secure network environments for production and development teams with specific connectivity and security requirements.
**Solution Requirements**:
### Production Network
1. **4-Tier Architecture**: Web, Application (App1/App2), Cache, and Database layers
2. **5 Subnets**: 1 public (web), 4 private (app1, app2, dbcache, db)
3. **Controlled Internet Access**: Only web, app1, and dbcache subnets can access internet
4. **Security**: Comprehensive security groups and NACLs
### Development Network
1. **2-Tier Architecture**: Web and Database layers
2. **Limited Internet Access**: Only web subnet can send internet requests
3. **Cross-Environment Access**: Database connectivity to production network
### Integration Requirements
1. **VPC Peering**: Connection between production and development networks
2. **Database Communication**: Direct connectivity between DB subnets
## 🏗️ Architecture
## 🔧 Technologies & Services Used
| Service | Purpose | Configuration |
|---------|---------|---------------|
| **VPC** | Network isolation | Production: 10.0.0.0/16, Development: 10.1.0.0/16 |
| **EC2** | Compute resources | Named instances per subnet |
| **Internet Gateway** | Internet connectivity | Attached to both VPCs |
| **NAT Gateway** | Private subnet internet | Production VPC only |
| **Route Tables** | Traffic routing | Separate tables for public/private |
| **Security Groups** | Instance-level firewall | Tier-based security rules |
| **NACLs** | Subnet-level security | Additional network protection |
| **VPC Peering** | Cross-VPC communication | Database subnet connectivity |

## 🚀 Quick Start
### Prerequisites
- AWS CLI configured with appropriate permissions
- Basic understanding of networking concepts
- SSH key pair for EC2 instance access
### Deployment Steps
1. **Clone the repository**
```bash
git clone https://github.com/himanshu2604/aws-vpc-architecture-solution.git
cd aws-vpc-architecture-solution
```
2. **Create Production VPC**
```bash
# Using AWS CLI (optional automation)
bash scripts/vpc-management/create-production-vpc.sh
```
3. **Deploy Development VPC**
```bash
# Setup development environment
bash scripts/vpc-management/create-development-vpc.sh
```
4. **Configure VPC Peering**
```bash
# Establish cross-VPC connectivity
bash scripts/peering-setup/setup-vpc-peering.sh
```
5. **Validate Deployment**
```bash
bash scripts/testing/validate-implementation.sh
```
## 📊 Results & Impact
