Getting Started with AWS Cloud Infrastructure
☁️ Getting Started with AWS Cloud Infrastructure
“How do I put my website online?”
That simple question is often the first step in learning AWS (Amazon Web Services).
🔍 What Is Cloud Infrastructure?
Traditionally, you had to buy and set up your own servers, storage, and networking equipment.
But with cloud infrastructure, you rent what you need over the internet—scalable, flexible, and cost-efficient.
AWS is one of the leading platforms that make this possible.
🌐 General Flow of Building Infrastructure on AWS
1. Create an Account and Set Up Essentials
Sign up for AWS and use the Free Tier for hands-on learning
Configure IAM (Identity and Access Management) to manage permissions securely
2. Launch a Virtual Server with EC2
EC2 provides a virtual computer in the cloud
Choose from various OS options like Ubuntu, Amazon Linux, or Windows
Set up a security group (acts like a firewall)
3. Use S3 to Store Files
Great for storing images, user uploads, and backups
Can also host static websites directly
4. Set Up a Database with RDS
Supports MySQL, PostgreSQL, Oracle, and more
Connects with EC2 to power dynamic web applications
5. Connect a Domain via Route 53
Link your custom domain (e.g.,
www.mysite.com) to EC2 or S3 to go live
🛠️ Real Example: Hosting a Portfolio Website
Launch an EC2 instance (e.g., with Ubuntu)
Install Apache and upload your HTML portfolio files
Open port 80 in the security group for HTTP traffic
Enter the public IP in a browser — your site is live!
💡 Want a custom URL? Use Route 53 to connect a domain like
www.mysite.com.
🔄 Easy Scaling and Automation with AWS
AWS isn't just for single-server apps. It supports full-scale infrastructure like:
| Feature | Description |
|---|---|
| Auto Scaling | Automatically adds servers during traffic spikes |
| Load Balancer | Distributes traffic evenly to avoid downtime |
| CloudWatch | Monitors performance and alerts for issues in real time |
☁️ Real-World Examples of AWS in Action
Baemin (Korean food delivery): Uses AWS to handle spikes during promotions
Coupang: Scales globally and ensures fast delivery via cloud infrastructure
Startups: Quickly launch MVPs (Minimum Viable Products) without heavy investment

✅ Final Thoughts
AWS can seem intimidating at first with its technical jargon. But once you start building—step by step—it gets easier.
And most importantly, doing it yourself is the best way to learn.
