AWS Project: VPC, EC2, RDS and Internet Gateway -

This project demonstrates a complete AWS infrastructure setup using Amazon VPC, EC2, RDS (MySQL), Internet Gateway, NAT Gateway, Route Tables, and Security Groups.
The goal was to deploy a secure, scalable web application architecture following AWS best practices.

---

🧱 Architecture Overview

• Custom VPC with public and private subnets
• Internet Gateway for public access
• NAT Gateway for private subnet outbound access
• EC2 instance hosting a web application
• Amazon RDS (MySQL) in private subnet
• Secure networking using route tables and security groups

---

🛠️ Services Used

• Amazon VPC
• Amazon EC2
• Amazon RDS (MySQL)
• Internet Gateway
• NAT Gateway
• Route Tables
• Security Groups
• AWS CloudShell

📌 Step-by-Step Implementation

1️⃣ Create VPC

Created a custom VPC with CIDR block 10.0.0.0/16.

---

2️⃣ Enable DNS Resolution & Hostnames

Enabled DNS resolution and DNS hostnames to support public resources.

---

3️⃣ Create Subnets

Created four subnets across two Availability Zones.

• Public-1A → 10.0.1.0/24
• Public-1B → 10.0.2.0/24
• Private-1A → 10.0.3.0/24
• Private-1B → 10.0.4.0/24

---

4️⃣ Verify Subnets

Confirmed all subnets were created successfully.

---

5️⃣ Create Private Route Table

Created a custom route table for private subnets.

---

6️⃣ Configure Route Table Routes

Added routes for internal traffic and internet access.

---

7️⃣ Route Tables Overview

Verified main and private route tables.

---

8️⃣ Associate Private Subnets

Associated private subnets with the private route table.

---

9️⃣ Create & Attach Internet Gateway

Created an Internet Gateway and attached it to the VPC.

---

🔟 Create NAT Gateway

Created NAT Gateway in public subnet for outbound internet access from private subnets.

---

1️⃣1️⃣ Configure Private Route Table for NAT

Updated private route table to route traffic through NAT Gateway.

---

1️⃣2️⃣ Create Security Group

Configured inbound and outbound rules for EC2 access.

---

1️⃣3️⃣ Launch EC2 Instance

Launched an EC2 instance using Amazon Linux AMI.

---

1️⃣4️⃣ Create RDS MySQL Database

Configured RDS MySQL database with free-tier eligible settings.

---

1️⃣5️⃣ Connect to EC2 via CloudShell

Connected to EC2 securely using SSH.

---

1️⃣6️⃣ Deploy Application & Database

Downloaded application files and configured MySQL database.

---

1️⃣7️⃣ Web Application Access

Successfully accessed the deployed web application.

---

✅ Final Outcome

• Secure AWS network architecture implemented
• EC2 connected to RDS using private networking
• Web application successfully deployed and tested
• Followed AWS best practices for security and availability
