AWS Services Overview

Compute Services

Amazon EC2 (Elastic Compute Cloud)

Virtual servers in the cloud. Use for applications requiring full OS control.

Use Cases: Web servers, application servers, batch processing

# Launch an EC2 instance
aws ec2 run-instances \
  --image-id ami-0c55b159cbfafe1f0 \
  --instance-type t3.micro \
  --key-name my-key-pair \
  --security-group-ids sg-0123456789abcdef \
  --subnet-id subnet-0123456789abcdef

AWS Lambda

Serverless compute - run code without managing servers.

Use Cases: API backends, data processing, automation tasks

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

Amazon ECS/Fargate

Container orchestration for Docker applications.

Use Cases: Microservices, containerized applications

Storage Services

Amazon S3 (Simple Storage Service)

Object storage for any type of data.

Use Cases: Backups, data lakes, static websites, media files

# Create a bucket
aws s3 mb s3://my-unique-bucket-name

# Upload a file
aws s3 cp myfile.txt s3://my-unique-bucket-name/

# List bucket contents
aws s3 ls s3://my-unique-bucket-name/

Amazon EBS (Elastic Block Store)

Block storage for EC2 instances.

Use Cases: Database storage, file systems, application data

Amazon EFS (Elastic File System)

Managed NFS file system that can be mounted by multiple EC2 instances.

Use Cases: Shared storage, content management, web serving

Database Services

Amazon RDS (Relational Database Service)

Managed relational databases (MySQL, PostgreSQL, Oracle, SQL Server).

Use Cases: Traditional applications, OLTP workloads

# Create a PostgreSQL RDS instance
aws rds create-db-instance \
  --db-instance-identifier mydb \
  --db-instance-class db.t3.micro \
  --engine postgres \
  --master-username admin \
  --master-user-password MyPassword123 \
  --allocated-storage 20

Amazon DynamoDB

Fully managed NoSQL database.

Use Cases: High-scale applications, gaming, IoT, mobile backends

# DynamoDB operations
import boto3

dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('Users')

# Put item
table.put_item(Item={'userId': '123', 'name': 'John Doe'})

# Get item
response = table.get_item(Key={'userId': '123'})

Amazon Aurora

MySQL and PostgreSQL-compatible database with enhanced performance.

Use Cases: Enterprise applications, SaaS platforms

Networking Services

Amazon VPC (Virtual Private Cloud)

Isolated virtual network for your AWS resources.

Use Cases: All AWS deployments requiring network isolation

# Create a VPC
aws ec2 create-vpc --cidr-block 10.0.0.0/16

# Create a subnet
aws ec2 create-subnet \
  --vpc-id vpc-0123456789abcdef \
  --cidr-block 10.0.1.0/24

Elastic Load Balancer

Distribute traffic across multiple targets.

Types: Application Load Balancer (ALB), Network Load Balancer (NLB), Gateway Load Balancer

Use Cases: High availability, auto scaling, SSL termination

Amazon CloudFront

Content Delivery Network (CDN) for fast content delivery.

Use Cases: Static websites, video streaming, API acceleration

Amazon Route 53

DNS and domain management service.

Use Cases: Domain registration, DNS routing, health checks

Architecture Best Practices

Security

Use VPC: Always deploy resources in a VPC
Security Groups: Implement least-privilege access
Encryption: Enable encryption at rest and in transit
IAM: Use roles instead of access keys
CloudTrail: Enable for audit logging
Secrets Manager: Store credentials securely

# Create a secret in Secrets Manager
aws secretsmanager create-secret \
  --name prod/db/password \
  --secret-string "MySecurePassword123"

High Availability

Multi-AZ: Deploy across multiple Availability Zones
Auto Scaling: Automatically adjust capacity
Load Balancing: Distribute traffic evenly
Health Checks: Monitor application health
Backups: Automated and tested regularly

Cost Optimization

Right-Sizing: Use appropriate instance types
Reserved Instances: Commit for 1-3 years to save up to 75%
Spot Instances: Use for fault-tolerant workloads (up to 90% savings)
Auto Scaling: Scale down during off-peak hours
S3 Lifecycle: Move data to cheaper storage classes
CloudWatch: Monitor and optimize resource usage

# Set up S3 lifecycle policy
aws s3api put-bucket-lifecycle-configuration \
  --bucket my-bucket \
  --lifecycle-configuration file://lifecycle.json

Performance

CDN: Use CloudFront for static content
Caching: Implement ElastiCache for databases
Database Optimization: Use read replicas, connection pooling
Async Processing: Use SQS/SNS for decoupling
Serverless: Use Lambda for event-driven workloads
