AWS Lambda Functions for Serverless Computing

Build serverless applications using AWS Lambda functions and learn best practices.

## AWS Cloud Architecture

### Infrastructure as Code with Terraform
```hcl
resource "aws_instance" "web_server" {
ami = "ami-0c55b159cbfafe1d0"
instance_type = "t3.micro"

tags = {
Name = "WebServer"
Environment = "Production"
}
}

resource "aws_s3_bucket" "app_storage" {
bucket = "my-app-storage-bucket"

versioning {
enabled = true
}
}
```

### Serverless with AWS Lambda
```python
import json
import boto3

def lambda_handler(event, context):
# Process the event
dynamodb = boto3.resource('dynamodb')
table = dynamodb.Table('MyTable')

response = table.put_item(
Item={
'id': event['id'],
'data': event['data']
}
)

return {
'statusCode': 200,
'body': json.dumps('Success')
}
```

### Container Orchestration with ECS
- Docker containerization strategies
- ECS task definitions and services
- Auto-scaling and load balancing
- CI/CD pipelines with CodePipeline

### Security and Monitoring
- IAM roles and policies
- VPC configuration and security groups
- CloudWatch monitoring and alerting
- AWS Config for compliance
