## AWS Well-Architected Framework

The AWS Well-Architected Framework provides best practices across six pillars:

### 1. Operational Excellence
- Automate infrastructure provisioning and configuration
- Monitor and measure system performance
- Continuously improve processes and procedures

### 2. Security
- Implement strong identity foundation
- Enable traceability and audit logging
- Apply security at all layers
- Protect data in transit and at rest

### 3. Reliability
- Automatically recover from failure
- Test recovery procedures
- Scale horizontally for resilience
- Manage change through automation

### 4. Performance Efficiency
- Use appropriate resource types and sizes
- Monitor performance and adapt
- Leverage serverless architectures
- Experiment with new technologies

### 5. Cost Optimization
- Adopt consumption-based pricing
- Measure and monitor spending
- Use cost-effective resources
- Optimize over time

### 6. Sustainability
- Understand environmental impact
- Maximize utilization of resources
- Use managed services
- Reduce downstream impact

## Compute Services

### Amazon EC2 (Elastic Compute Cloud)

EC2 provides resizable compute capacity in the cloud, offering complete control over computing resources.

#### EC2 Instance Types

```bash
# List available instance types in a region
aws ec2 describe-instance-types \
  --region us-east-1 \
  --query 'InstanceTypes[*].[InstanceType,VCpuInfo.DefaultVCpus,MemoryInfo.SizeInMiB]' \
  --output table
```

#### Launch EC2 Instance with User Data

```yaml
# CloudFormation: EC2 Instance with Auto Scaling
AWSTemplateFormatVersion: '2010-09-09'
Description: EC2 instance with user data for web server

Parameters:
  InstanceType:
    Type: String
