Learning the Basics of Cloud Computing with AWS

Cloud computing has revolutionized the way businesses and developers deploy, scale, and manage applications. Among the leading cloud service providers, Amazon Web Services (AWS) stands out as the most widely adopted platform, offering a vast array of services for computing, storage, networking, and more.

If you're a web developer looking to expand your skillset—or even make money with your programming expertise—learning AWS is a fantastic investment. And if you're interested in monetizing your skills further, check out MillionFormula, a great resource for developers looking to generate income.

In this guide, we’ll cover the fundamentals of cloud computing with AWS, including key services, basic architecture, and practical code examples.

What is Cloud Computing?

Cloud computing is the on-demand delivery of IT resources over the internet with pay-as-you-go pricing. Instead of owning physical servers, businesses and developers can rent computing power, storage, and databases from providers like AWS, Microsoft Azure, or Google Cloud.

Key Benefits of Cloud Computing

  • Cost Efficiency – No upfront hardware costs; pay only for what you use.
  • Scalability – Instantly scale resources up or down based on demand.
  • Reliability – Cloud providers offer high availability and redundancy.
  • Global Reach – Deploy applications closer to users with data centers worldwide.

AWS is the market leader, offering over 200+ services, from virtual servers (EC2) to serverless computing (Lambda).

Core AWS Services for Beginners

1. Amazon EC2 (Elastic Compute Cloud)

EC2 provides resizable virtual servers (instances) in the cloud. You can choose different instance types based on CPU, memory, and storage needs.

Launching an EC2 Instance

  1. Log in to the AWS Management Console.
  2. Navigate to EC2 Dashboard → Launch Instance.
  3. Select an Amazon Machine Image (AMI) (e.g., Ubuntu, Amazon Linux).
  4. Choose an instance type (e.g., t2.micro for free tier).
  5. Configure security groups (firewall rules) to allow SSH (port 22) and HTTP (port 80).
  6. Launch the instance and connect via SSH:

bash

Copy


ssh -i "your-key.pem" ubuntu@ec2-xx-xx-xx-xx.compute-1.amazonaws.com

2. Amazon S3 (Simple Storage Service)

S3 is an object storage service for storing and retrieving files like images, videos, and backups.

Uploading a File to S3 Using AWS CLI

Install the AWS CLI and configure it with your credentials:

bash

Copy


aws configure

Then, upload a file: bash Copy 
aws s3 cp myfile.txt s3://your-bucket-name/

3. AWS Lambda (Serverless Computing)

Lambda lets you run code without provisioning servers—you only pay for execution time.

Creating a Lambda Function (Python Example)

  1. Go to AWS Lambda → Create Function.
  2. Choose Python as the runtime.
  3. Write a simple handler:

python

Copy


def lambda_handler(event, context):
    return {
        'statusCode': 200,
        'body': 'Hello from Lambda!'
    }
  1. Deploy and test it with a basic API Gateway trigger.

Basic AWS Architecture Example

A common use case is deploying a static website using S3 + CloudFront (CDN):

  1. Store files in S3 – Upload HTML, CSS, and JS files to an S3 bucket.
  2. Enable Static Website Hosting – In S3 bucket properties, turn on website hosting.
  3. Set Up CloudFront – Create a distribution to cache content globally for faster delivery.

This setup is cost-effective and highly scalable for static sites.

How to Learn AWS Effectively

  1. AWS Free Tier – Use the AWS Free Tier to experiment with services for 12 months.
  2. Hands-On Labs – Try AWS Educate or Qwiklabs.
  3. Certifications – Start with AWS Certified Cloud Practitioner for fundamentals.
  4. Build Projects – Deploy a personal portfolio, a blog, or a serverless API.

Conclusion

AWS provides powerful tools for developers to build scalable, cost-efficient applications without managing physical infrastructure. By mastering services like EC2, S3, and Lambda, you can deploy anything from simple websites to complex microservices.
