09. AWS Snow Family & Hybrid Cloud Storage
The AWS Snow Family consists of highly secure, portable, and rugged devices that help you collect, process, and migrate data into and out of AWS — especially when internet transfer is slow, expensive, or unreliable.
It also enables edge computing, allowing data processing at remote or disconnected locations (ships, trucks, mines, etc.).
🧩 AWS Snow Family Overview
| Device | Use Case | Capacity | Transfer Mode | Key Features |
|---|---|---|---|---|
| Snowcone | Small edge computing & data transfer | 8 TB usable | Offline / Online | Lightweight (2.1 kg), rugged, supports battery power |
| Snowball Edge (Storage Optimized) | Data migration, storage | 80 TB usable | Offline | High-capacity HDD, S3-compatible storage |
| Snowball Edge (Compute Optimized) | Edge computing | 42 TB usable | Offline | 52 vCPUs, 208 GiB RAM, optional GPU |
| Snowmobile | Massive data migration | 100 PB per truck | Offline | Exabyte-scale transfer, extreme security |
🚚 Data Migration Use Cases
If transferring large datasets (TBs or PBs) over the internet takes too long, Snowball devices provide a physical transport alternative.
⚙️ How Snowball Data Migration Works
- Request Device – Order from AWS Console.
- Receive Device – AWS ships Snowball to your site.
- Connect & Load Data – Use Snowball Client or AWS OpsHub to transfer data.
- Return Device – Ship back to AWS; shipping is free.
- AWS Imports Data – Data is moved into your S3 bucket.
- Device Sanitized – Data wiped securely per NIST standards.
🧠 Edge Computing with Snow Family
Edge computing allows data to be processed where it’s created, minimizing latency and bandwidth use.
🏗️ Example Scenarios
- Ship at sea with no internet
- Truck generating telemetry data
- Remote mining operation
💡 Benefits
- Preprocess data before uploading
- Run machine learning inference locally
- Transcode media or compress files offline
💻 Compute Capabilities
| Device | vCPUs | Memory | Storage | Notes |
|---|---|---|---|---|
| Snowcone | 2 | 4 GiB | 8 TB | Wired/wireless access |
| Snowball Edge Compute Optimized | 52 | 208 GiB | 42 TB | Optional GPU |
| Snowball Edge Storage Optimized | 40 | 80 GiB | 80 TB | Object storage clustering |
🧩 Both can run EC2 instances & AWS Lambda functions via AWS IoT Greengrass.
🧰 AWS OpsHub
AWS OpsHub is a GUI application used to manage Snow Family devices (replaces CLI-only setup).
🔧 Features
- Unlock & configure devices
- Transfer files
- Launch/manage EC2 instances or Lambda functions
- Monitor storage & performance
- Access compatible services (e.g., AWS DataSync, NFS)
💰 Snowball Edge Pricing
| Component | Description |

| Extra Day Charges | Charged per day beyond included usage |
| Shipping | Free (to/from AWS) |
| Data Import to S3 | $0 per GB (free) |
| Data Export from S3 | Charged per GB transferred out |
| Long-Term Commitment | Monthly, 1-year, or 3-year plans for edge computing (up to 62% discount) |
🧱 Hybrid Cloud Storage
AWS promotes hybrid cloud setups where part of infrastructure is on-premises and part in the AWS Cloud.
🏢 Why Hybrid?
- Long-term migration strategy
- Security or compliance needs
- Data sovereignty
- Gradual cloud adoption
🔗 AWS Storage Gateway
AWS Storage Gateway bridges on-premises storage systems and AWS Cloud storage.
| Type | Description | Backend AWS Storage |
|---|---|---|
| File Gateway | Store and access files as objects in S3 | S3 |
| Volume Gateway | Block-level storage volumes (cached or stored mode) | EBS + S3 |
| Tape Gateway | Virtual tape library for backup software | Glacier & S3 Glacier Deep Archive |
🧩 Use Cases
- Backup & restore
- Disaster recovery
- Cloud tiering
- Extending on-premises storage seamlessly
🧾 AWS Storage Categories Summary
| Category | AWS Service | Description |
|---|---|---|
| Block Storage | EBS, Instance Store | Low-latency volumes for EC2 |
| File Storage | EFS | Shared, scalable file system (NFS) |
| Object Storage | S3, Glacier | Store data as objects (key/value pairs) |
| Hybrid Storage | Storage Gateway | Bridge on-premises & AWS Cloud |
| Physical Data Transfer | Snow Family | Offline data migration or edge computing |
🧭 Exam Tips (AWS Certified Cloud Practitioner)
✅ Use Snow Family for large data transfers (TB–PB scale) or edge processing.
✅ Use Snowmobile for exabyte-scale migrations.
✅ Use Storage Gateway for hybrid storage integration.
✅ Data import into S3 is always free.
