AWS Snow Family Overview: Empowering Data Migration and Edge Computing

Introduction

AWS Snow Family is a suite of physical devices that AWS offers to facilitate the transfer of large amounts of data in and out of the cloud, as well as to enable edge computing. These devices are essential for organizations that face challenges related to data transfer speeds, bandwidth limitations, or need to perform data processing closer to the point of data generation. In this blog post, we'll provide an overview of the AWS Snow Family, and then dive into a specific architecture—using Snowball to transfer data into Amazon Glacier—with a supporting diagram.

What is the AWS Snow Family?❄

The AWS Snow Family consists of three main services: Snowcone, Snowball, and Snowmobile. Each of these services caters to different use cases based on the amount of data being transferred and the requirements for processing data at the edge.

1. AWS Snowcone:

   • Description: The smallest member of the Snow Family, Snowcone is a portable, rugged, and secure edge computing and data transfer device. It's designed for small-scale data transfers and can be carried easily due to its compact size.

   • Use Cases: Ideal for scenarios where only a few terabytes of data need to be transferred or where a small edge computing device is needed.

2. AWS Snowball:

   • Description: Snowball comes in two variants: Snowball Edge Storage Optimized and Snowball Edge Compute Optimized. These devices are larger than Snowcone and are designed for larger-scale data transfer and edge computing.

   • Use Cases: Suitable for data transfers ranging from terabytes to petabytes and for edge computing use cases where powerful processing capabilities are required.

3. AWS Snowmobile:

   • Description: The largest member of the family, Snowmobile is a literal truck that can transport exabytes of data. It's a massive, secure data transfer service for organizations needing to migrate vast amounts of data to AWS.

   • Use Cases: Ideal for large-scale data center migrations involving exabytes of data.

Key Features of the AWS Snow Family:

• Secure Data Transfer: All Snow Family devices offer end-to-end encryption, ensuring that your data is secure during transit.

• Rugged and Portable: The devices are designed to be durable and can operate in harsh environments, making them ideal for remote or field operations.

• Edge Computing: Snowcone and Snowball devices offer built-in compute capabilities, allowing you to process data locally before transferring it to the cloud.

• Scalable: Whether you're transferring terabytes or exabytes, the Snow Family provides a solution that fits your needs.

Architecture: Using Snowball to Transfer Data into Amazon Glacier⚡

In many scenarios, organizations need to archive large volumes of data in a cost-effective and secure manner. Amazon Glacier offers long-term data storage at low costs, making it an ideal solution for archival purposes. However, transferring petabytes of data over the internet to Glacier can be time-consuming and costly. This is where AWS Snowball comes in.

Architecture Overview:

Step 1: Data Collection

• The organization collects data from various sources, such as data centers, edge locations, or remote sites. This data can include backups, logs, or any other large datasets that need to be archived.

Step 2: Request Snowball

• The organization requests a Snowball device from AWS through the AWS Management Console. AWS ships the Snowball device to the organization's location.

Step 3: Data Transfer to Snowball

• The organization connects the Snowball device to their local network. Using the Snowball client software, the organization transfers the collected data onto the Snowball device. The data is encrypted during the transfer.

Step 4: Ship Snowball Back to AWS

• Once the data transfer is complete, the Snowball device is shipped back to AWS. The device's E Ink shipping label automatically updates with the correct return address, simplifying logistics.

Step 5: Data Transfer to S3 Glacier

• Upon receiving the Snowball device, AWS transfers the data to Amazon S3. The data is then moved into Amazon Glacier (S3 Glacier), where it is stored securely and at a low cost for long-term retention.

Step 6: Data Access and Management

• The organization can manage and retrieve the data stored in Glacier using the AWS Management Console, CLI, or SDKs. Data retrieval from Glacier may take some time depending on the retrieval option chosen (Standard, Expedited, or Bulk).

Below is a simplified architecture diagram illustrating the process of transferring data from a local environment to Amazon Glacier using AWS Snowball.

Use Cases:

1. Large-Scale Data Center Migrations:

   • For organizations needing to decommission data centers or migrate large amounts of data to the cloud, Snowball provides a cost-effective and efficient way to transfer data without overloading network bandwidth.

2. Long-Term Data Archival:

   • Snowball and Glacier together offer an ideal solution for archiving large datasets that need to be stored securely for long periods but are infrequently accessed.

3. Edge Data Processing and Transfer:

   • In remote locations where internet connectivity is limited or nonexistent, Snowball's edge computing capabilities allow for local data processing and subsequent secure transfer to AWS when connectivity is available.

Real-Life Example:

Case Study: Digital Globe’s Satellite Imagery

• Digital Globe, a leading provider of high-resolution Earth imagery, needed to transfer over 100 petabytes of satellite data to AWS for archival and analysis. Using AWS Snowball, they efficiently moved this massive dataset to Amazon S3, from where it was archived into Glacier. The secure and efficient transfer process ensured that the data was protected during transit and could be accessed or analyzed on demand using AWS services.

Conclusion💡

The AWS Snow Family is a versatile suite of devices that empowers organizations to manage data transfer and edge computing efficiently. Whether you need to transfer terabytes or exabytes of data, Snowcone, Snowball, and Snowmobile offer secure, scalable, and cost-effective solutions. When combined with Amazon Glacier, these devices enable seamless long-term data archiving, ensuring that your valuable data is securely stored and easily accessible whenever needed.
