# Explanation: Parallelismi Storage Docker ↔ AWS

## Core Concepts

### Docker Named Volume = EBS Volume

| Aspect | Docker | AWS EBS |
|--------|--------|---------|
| Creation | docker volume create | aws ec2 create-volume |
| Lifecycle | Indipendent dal container | Indipendente dall'istanza |
| Persistence | Sopravvive a docker rm | Sopravvive a ec2 terminate |
| Mount | volumes: section in compose | Attach to /dev/sdX |
| Backup | docker run --rm tar | EBS snapshots |

### MinIO = S3

| Aspect | MinIO | AWS S3 |
|--------|-------|--------|
| API | 100% S3 compatible | Native S3 |
| Endpoint | http://localhost:9000 | https://s3.amazonaws.com |
| Pricing | Free (self-hosted) | Pay-per-use |
| Use case | Local dev/test | Production |

## Storage Architecture Patterns

### Database with Persistent Storage
**Locale:**
```yaml
db:
  image: postgres
  volumes:
    - db-data:/var/lib/postgresql/data
```
**Cloud:** RDS con EBS storage

### Object Storage
**Locale:**
```yaml
minio:
  image: minio/minio
  volumes:
    - minio-data:/data
```
**Cloud:** S3 bucket

## Key Differences

1. **Scope:** Volumes = single host, EBS = AZ-wide
2. **Performance:** Local filesystem vs network storage
3. **Backup:** tar vs EBS snapshots
4. **Scaling:** Manual vs S3 infinite scale

## When to Use What

| Use Case | Locale | Cloud |
|----------|--------|-------|
| Dev database | PostgreSQL + Volume | RDS |
| File storage | Volume | EFS |
| Objects | MinIO | S3 |
| Backup | tar to host | S3 Glacier |

## Conclusion
Docker volumes e MinIO seguono gli stessi principi di EBS e S3, permettendoti di praticare localmente prima di deployare in cloud.
