Hey Web Codders! 👋 I’m Vikas Sankhla, your tech buddy from Web Codder, and today we’re diving into something SUPER COOL: Amazon EC2. 😄

You might be wondering:

👉 What is EC2?
👉 How can I use it to host my app?
👉 Is it hard to set up?

Don’t worry! I’m going to explain everything step-by-step, super simple.

🌟 What Is Amazon EC2?

Let’s imagine this: You want to run your app on a powerful computer that’s always online.

Instead of buying your own computer, Amazon rents you one on the internet! 💻☁️

That’s what EC2 (Elastic Compute Cloud) is—a virtual server you can use anytime, anywhere. 🚀

💡 In simple words:
EC2 = A computer in the cloud that runs your app. ✅

🖥️ Why Do We Need EC2?

• Your app needs a home 🏠 (a server).
• You want your app to be available 24/7. 🕒
• You don’t want to worry about hardware & electricity. 🔌

EC2 solves all that by giving you:

✅ A computer that’s always on.
✅ The ability to choose your power.
✅ Global access (users from anywhere can visit).

🛠️ How to Set Up an EC2 Instance (Step-by-Step)

Let’s host your app on EC2. Follow these easy steps:

1️⃣ Sign In to AWS Console

👉 Go to aws.amazon.com
👉 Log in or create an account.

Note: AWS gives you free tier access for 12 months! 🎉

2️⃣ Launch a New EC2 Instance 🚀

• Click “EC2” in the services menu.
• Click “Launch Instance.”

✅ Choose an Amazon Machine Image (AMI):
Pick Ubuntu Server 20.04 LTS (free tier eligible).

✅ Choose Instance Type:
Pick t2.micro (also free tier!).

3️⃣ Configure Instance Details 🛠️

• Number of instances: 1
• Network: Default VPC
• Subnet: Pick one (closest to your region)

💡 You can leave most settings as default.

4️⃣ Add Storage 💾

Default: 8GB is fine for small apps.

5️⃣ Add Tags 🏷️

Example:
Key: Name
Value: MyFirstEC2

(Helps you identify your instance later!)

6️⃣ Configure Security Group 🔐

👉 Allow SSH (port 22) so you can connect.
👉 Allow HTTP (port 80) if you’re hosting a website.
👉 Optional: Allow HTTPS (port 443) for secure sites.

(⚠️ Always be careful with security—don’t allow too much open access!)

7️⃣ Launch 🚀

• Click “Launch.”
• Choose “Create new key pair.”
• Download the .pem file (IMPORTANT: Keep this safe!).

👉 Tip: Always choose a region near your users for best speed! ⚡

🔗 How to Connect to Your EC2 Instance (SSH)

You’ve launched your EC2—yay! 🎉 Now let’s log in to your cloud server.

1️⃣ Open Terminal (Mac/Linux) or PowerShell (Windows)

2️⃣ Use SSH Command

Example:

bashCopyEditssh -i /path/to/your-key.pem ubuntu@your-ec2-public-ip

👉 Replace:

• /path/to/your-key.pem = Your downloaded key file path.
• your-ec2-public-ip = Find it in EC2 dashboard (Public IPv4).

💡 First time? It might ask:
Are you sure you want to connect?
Type: yes ✅

🔐 Set Up Security Credentials

Remember: Never share your .pem file or your server IP publicly! 🚨

You can also:

• Create IAM roles/users for better access control.
• Set up firewall rules (in Security Groups).

1️⃣ Create EC2
2️⃣ Configure security 🔐
3️⃣ Launch 🚀
4️⃣ Connect via SSH 🔗
5️⃣ Host your app 🌍

🏁 Conclusion: Your First EC2 Server Is Live! 🚀

Awesome job, coder fam! 🎉 You just set up a real cloud server using EC2. 😎

Now you can:

• Host websites
• Run backend apps
• Experiment with servers like a pro developer. 💻
