Overview

Amazon EC2 provides resizable compute capacity in the cloud. Launch and configure virtual servers with complete control over networking, storage, and security settings. Scale automatically based on demand.

When to Use

Web application servers

Application backends and APIs

Batch processing and compute jobs

Development and testing environments

Containerized applications (ECS)

Kubernetes clusters (EKS)

Database servers

VPN and proxy servers

Quick Start

Minimal working example:

# Create security group
aws ec2 create-security-group \
  --group-name web-server-sg \
  --description "Web server security group" \
  --vpc-id vpc-12345678

# Add ingress rules
aws ec2 authorize-security-group-ingress \
  --group-id sg-0123456789abcdef0 \
  --protocol tcp \
  --port 80 \
  --cidr 0.0.0.0/0

aws ec2 authorize-security-group-ingress \
  --group-id sg-0123456789abcdef0 \
  --protocol tcp \
  --port 443 \
  --cidr 0.0.0.0/0

aws ec2 authorize-security-group-ingress \
  --group-id sg-0123456789abcdef0 \
  --protocol tcp \
  --port 22 \
  --cidr YOUR_IP/32

Best Practices

✅ DO

Use security groups for network control

Attach IAM roles for AWS access

Enable CloudWatch monitoring

Use AMI for consistent deployments

Implement auto-scaling for variable load

Use EBS for persistent storage

Enable termination protection for production

Keep systems patched and updated

❌ DON'T

Use overly permissive security groups

Store credentials in user data

Ignore CloudWatch metrics

Use outdated AMIs

Create hardcoded configurations

Forget to monitor costs
