Build and Manage a Virtual Private Cloud (VPC)

Set up a fully customizable cloud network using a VPC with private/public subnets, NAT gateway, internet gateway, route tables, and network security groups.

Why Use a Virtual Private Cloud?

A VPC allows you to isolate your cloud resources in a logically separate environment. With customizable subnets, routing rules, and firewalls, VPCs are essential for building secure and scalable architectures in AWS, Azure, or GCP.

Project Objectives

Create a complete VPC network layout with internet-facing (public) and backend (private) subnets. Configure routing, deploy EC2 or VM instances in isolated zones, and manage security rules using groups and ACLs.

Key Components to Implement

VPC and Subnet Configuration

Create a VPC with multiple subnets (public/private) across availability zones.

Internet Gateway & NAT Gateway

Attach an internet gateway for public access and NAT gateway for outbound internet in private subnets.

Route Tables & DNS

Create custom route tables and enable DNS resolution for cloud instances.

Security Groups and NACLs

Control traffic in and out of subnets and EC2 instances using firewall rules and ACLs.

System Architecture Overview

You'll design and deploy a network that mimics enterprise-grade cloud architecture. It includes at least two public and two private subnets across multiple AZs. You will deploy EC2 instances, apply firewall rules, and test internet access from each subnet.

  • VPC CIDR Block: 10.0.0.0/16
  • Subnets: 2 public + 2 private across 2 availability zones
  • Gateways: Internet Gateway for public; NAT Gateway for private
  • Instances: EC2 or Compute Engine VMs deployed to test access rules
  • Monitoring: Use VPC Flow Logs for traffic insight
Tech Stack Suggestions

Cloud Providers

AWS (VPC, EC2, NAT, IGW), GCP (VPC, firewall rules), Azure VNets

Configuration Tools

Terraform, AWS CLI, CloudFormation, GCP gcloud CLI

Operating Systems

Ubuntu EC2 VMs or Windows Server for testing access between networks

Logging & Monitoring

AWS VPC Flow Logs, CloudWatch Logs, GCP Stackdriver, Azure Network Watcher

Step-by-Step Implementation Guide

1. Create a VPC and Subnets

Define a CIDR block and create multiple public and private subnets.

2. Attach Gateways and Routing

Create an Internet Gateway, a NAT Gateway, and set up custom route tables.

3. Launch EC2 Instances

Deploy Linux/Windows instances in both subnet types and configure SSH/HTTP access.

4. Apply Security Groups and ACLs

Implement granular traffic control at both instance and subnet levels.

5. Test and Monitor

Ping public internet, access private services, and review logs via Flow Logs or dashboards.
