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 a dominant force, offering a vast array of services that cater to computing, storage, networking, and more.

If you're new to cloud computing, AWS provides an excellent platform to start learning. This guide will walk you through the fundamentals of AWS, key services, and how to get hands-on with simple deployments.

What is Cloud Computing?

Cloud computing refers to the on-demand delivery of IT resources over the internet with a pay-as-you-go pricing model. Instead of owning physical servers, businesses 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.

• Flexibility – Access services from anywhere with an internet connection.

• Reliability – Cloud providers offer high availability and disaster recovery.

Core AWS Services to Get Started

AWS offers over 200+ services, but beginners should focus on these foundational ones:

1. Amazon EC2 (Elastic Compute Cloud)

EC2 provides virtual servers (instances) in the cloud. You can launch a Linux or Windows machine in minutes.

Launching an EC2 Instance

1. Log in to the AWS Management Console.

2. Navigate to EC2 Dashboard > Launch Instance.

3. Choose an Amazon Machine Image (AMI) (e.g., Amazon Linux 2).

4. Select an instance type (e.g., t2.micro for free tier).

5. Configure security groups (allow SSH for Linux or RDP for Windows).

6. Launch the instance and connect using SSH (Linux) or Remote Desktop (Windows).

bash

Copy

Download

# Example SSH command (replace with your key and public IP)
ssh -i "your-key.pem" ec2-user@your-instance-ip

2. Amazon S3 (Simple Storage Service)

S3 is an object storage service ideal for storing files, backups, and static website hosting.

Uploading a File to S3

1. Go to the S3 Console > Create Bucket.

2. Enter a unique bucket name (e.g., my-first-bucket-2024).

3. Upload a file via the AWS Console or AWS CLI:

bash

Copy

Download

# Install AWS CLI (if not installed)
pip install awscli

# Configure AWS credentials
aws configure

# Upload a file to S3
aws s3 cp my-file.txt s3://my-first-bucket-2024/

3. AWS Lambda (Serverless Computing)

Lambda lets you run code without managing servers—perfect for event-driven applications.

Creating a Lambda Function

1. Open the Lambda Console > Create Function.

2. Select Author from scratch, name your function, and choose Python/Node.js.

3. Write a simple function:

python

Copy

Download

def lambda_handler(event, context):
    return {
        'statusCode': 200,
        'body': 'Hello from AWS Lambda!'
    }

4. Deploy and test it with a sample event.
