Introduction

This tutorial will guide you through the basics of getting started with cloud computing on Amazon Web Services (AWS). Designed for beginners, this step-by-step guide will help you understand the fundamental concepts and provide practical advice for launching your first cloud project.

Step 1: Create an AWS Account

To begin using AWS, you need to create an account.

• Visit the AWS website.
• Click on "Create a Free Account."
• Fill in your email address and set a password.
• Follow the prompts to provide your account information and payment details. Note that AWS offers a free tier for new users.

Step 2: Navigate the AWS Management Console

After setting up your account, familiarize yourself with the AWS Management Console.

• Log in to your AWS account.
• Explore the dashboard to see the various services available.
• Use the search bar at the top to find specific services like EC2, S3, or Lambda.

Step 3: Launch an EC2 Instance

EC2 (Elastic Compute Cloud) allows you to run virtual servers on AWS.

• In the Management Console, locate and click on "EC2" under the Services menu.
• Click on "Launch Instance."
• Choose an Amazon Machine Image (AMI). For beginners, select the "Amazon Linux 2" AMI.
• Select the instance type (e.g., t2.micro) which is eligible for the free tier.
• Configure instance details and proceed to add storage and tags as needed.
• Review your configuration and click "Launch."
• Select or create a key pair for SSH access and click "Launch Instances."

Step 4: Access Your EC2 Instance

Once your instance is running, you will need to connect to it.

• In the EC2 dashboard, select your instance and note its Public DNS (IPv4).
• Use an SSH client (like Terminal on macOS/Linux or PuTTY on Windows) to connect:

  ssh -i "your-key-pair.pem" ec2-user@your-public-dns
  

• Replace "your-key-pair.pem" with the path to your key file and your-public-dns with the actual DNS address.

Step 5: Explore AWS S3 for Storage

AWS S3 (Simple Storage Service) is ideal for storing and retrieving any amount of data.

• Go back to the AWS Management Console and find "S3" in the Services menu.
• Click "Create Bucket" and enter a unique name.
• Choose the region and click "Create."
• Upload files to your bucket by clicking on "Upload" and following the prompts.

Step 6: Set Up IAM for Security

IAM (Identity and Access Management) is crucial for controlling access to your AWS resources.

• In the AWS Management Console, find "IAM" in the Services menu.
• Click on "Users" and then "Add user."
• Assign permissions based on the user’s role (e.g., Admin, Read-only).
• Create access keys if programmatic access is required.

Conclusion

You have now covered the basics of getting started with AWS, including creating an account, launching an EC2 instance, using S3 for storage, and setting up IAM for security. As next steps, consider exploring more AWS services and resources to deepen your understanding, or participate in community discussions on platforms like Discord or social media.
