🌟 Why Learn EC2?

  • 🚀 Cloud Computing Mastery: EC2 is the backbone of AWS services.
  • 💼 Career Growth: EC2 knowledge is crucial for DevOps, cloud engineers, and developers.
  • 🌍 Real-World Applications: Use EC2 to host websites, deploy applications, or run data pipelines.

🚀 Getting Started

Prerequisites

Before you begin, ensure you have:

  • ✅ An AWS account (free-tier eligible).
  • ✅ Basic knowledge of cloud computing.

📦 EC2 Instance Types

AWS EC2 offers various instance types tailored for different workloads:

Type Use Case Examples
General Balanced performance t2.micro, t3.small
Compute High-performance computing c5.large, c6i.xlarge
Memory Memory-intensive apps r5.large, r6g.xlarge
Storage Data-heavy workloads i3.large, i4i.xlarge
GPU Machine learning, gaming g5.large, p3.2xlarge

⚙️ Launching an EC2 Instance

Follow these steps to launch your first EC2 instance:

  1. Login to AWS Console 🖥️

    • Navigate to EC2 under the "Compute" section.

  2. Click "Launch Instance" 🚀

    • Provide a name for your instance.
    • Select an AMI (Amazon Machine Image) like Ubuntu, Amazon Linux, or Windows Server.

  3. Choose an Instance Type 🖱️

    • For beginners, choose t2.micro (free-tier eligible).

  4. Configure Security Groups 🔒

    • Add rules to allow inbound traffic for HTTP (port 80) and SSH (port 22).

  5. Key Pair 🗝️

    • Create or select an existing key pair for secure access.

  6. Launch Your Instance 🎉

    • Click Launch Instance and wait for it to initialize.

🌐 Hosting a Simple Webpage

Here’s how you can host a basic index.html file on your EC2 instance.

Step 1: Install a Web Server

Log into your EC2 instance via SSH and run the following commands to install a web server:

# Update the package manager
sudo apt update  

# Install Apache2
sudo apt install apache2 -y  

# Start Apache2 service
sudo systemctl start apache2  

# Enable Apache2 to start on boot
sudo systemctl enable apache2

Step 2: Create Your Webpage

Navigate to the default web server directory and create an index.html file:

# Navigate to the default directory
cd /var/www/html  

# Create or edit the index.html file
sudo nano index.html

Add the following content to your index.html file:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Welcome to My Webpage</title>
</head>
<body>
    <h1>🚀 Welcome to My First AWS EC2 Hosted Webpage!</h1>
    <p>This is a simple webpage hosted on an EC2 instance.</p>
</body>
</html>

Save and exit (Ctrl+O, Enter, Ctrl+X).

Step 3: Open Your Webpage

  • In your browser, navigate to: http://<Public_IP_of_EC2_Instance>

You should see your index.html webpage live! 🎉

🔒 Security Best Practices

  1. Use Security Groups: Restrict inbound traffic to only required ports.
  2. Key Management: Keep your .pem file secure.
  3. IAM Roles: Assign least privilege roles to your instances.

🎉 Conclusion

With this guide, you’ve:

  • Launched your first EC2 instance.
  • Installed a web server.
  • Hosted your first index.html webpage.

Continue exploring AWS to enhance your cloud computing skills!
