Getting Started with AWS

In this chapter, we'll set up your AWS environment and learn about the fundamental concepts of AWS cloud computing.

AWS Account Setup

Creating an AWS Account

  1. Visit aws.amazon.com
  2. Click "Create an AWS Account"
  3. Follow the registration process
  4. Add payment information (required, but using free tier)

Security Best Practices

# Install AWS CLI
curl "https://awscli.amazonaws.com/AWSCLIV2.pkg" -o "AWSCLIV2.pkg"
sudo installer -pkg AWSCLIV2.pkg -target /

# Configure AWS CLI
aws configure

Identity and Access Management (IAM)

Creating an IAM User

  1. Navigate to IAM in AWS Console
  2. Create a new user
  3. Set permissions
  4. Generate access keys
# Test AWS CLI configuration
aws iam get-user

IAM Best Practices

  • Use MFA for root account
  • Create individual IAM users
  • Use groups for permissions
  • Follow least privilege principle
  • Regularly rotate credentials

AWS Regions and Availability Zones

Understanding Global Infrastructure

import boto3

# List all AWS regions
ec2 = boto3.client('ec2')
regions = ec2.describe_regions()
for region in regions['Regions']:
    print(f"Region: {region['RegionName']}")

Choosing the Right Region

Factors to consider:

  • Latency to users
  • Service availability
  • Data sovereignty
  • Pricing

Core AWS Services Overview

Compute Services

  • EC2 (Virtual Servers)
  • Lambda (Serverless)
  • ECS/EKS (Containers)

Storage Services

  • S3 (Object Storage)
  • EBS (Block Storage)
  • EFS (File System)

Database Services

  • RDS (Relational)
  • DynamoDB (NoSQL)

Hands-on Exercise

Create Your First EC2 Instance

# Create key pair
aws ec2 create-key-pair --key-name MyKeyPair --query 'KeyMaterial' --output text > MyKeyPair.pem

# Launch EC2 instance
aws ec2 run-instances \
    --image-id ami-0c55b159cbfafe1f0 \
    --instance-type t2.micro \
    --key-name MyKeyPair

# Check instance status
aws ec2 describe-instances

Cost Management

Free Tier Usage

  • Monitor usage in AWS Console
  • Set up billing alerts
  • Understand service limits
# Get billing information
aws ce get-cost-and-usage \
    --time-period Start=2024-01-01,End=2024-01-31 \
    --granularity MONTHLY \
    --metrics "UnblendedCost" "UsageQuantity"

Next Steps

In the next chapter, we'll dive deeper into:

  • VPC networking
  • Security groups
  • EC2 instance management
  • Storage configuration

Remember to always follow AWS best practices and security guidelines as you continue your cloud journey.
