AWS Snowball Edge Cheat Sheet

• A type of Snowball device with on-board storage and compute power for select AWS capabilities. It can undertake local processing and edge-computing workloads in addition to transferring data between your local environment and the AWS Cloud.
• Has on-board S3-compatible storage and compute to support running Lambda functions and EC2 instances.
• Options for device configurations
  • Storage optimized – this option has the most storage capacity at up to 80 TB of useable storage space, 24 vCPUs, and 32 GiB of memory for compute functionality. You can transfer up to 100 TB with a single Snowball Edge Storage Optimized device.
  • Compute optimized – this option has the most compute functionality with 52 vCPUs, 208 GiB of memory, and 7.68 TB of dedicated NVMe SSD storage for instances. This option also comes with 42 TB of additional storage space.
  • Compute Optimized with GPU – identical to the compute optimized option, save for an installed GPU, equivalent to the one available in the P3 Amazon EC2 instance type.

Features

• Network adapters with transfer speeds of up to 100 GB/second.
• Encryption is enforced, protecting your data at rest and in physical transit.
• You can import or export data between your local environments and S3.
• Snowball Edge devices come with an on-board LCD display that can be used to manage network connections and get service status information.
• You can cluster Snowball Edge devices for local storage and compute jobs to achieve 99.999 percent data durability across 5–10 devices, and to locally grow and shrink storage on demand.
• You can use the file interface to read and write data to a Snowball Edge device through a file share or Network File System (NFS) mount point.
• You can write Python-language Lambda functions and associate them with S3 buckets when you create a Snowball Edge device job. Each function triggers whenever there’s a local S3 PUT object action executed on the associated bucket on the appliance.
• Snowball Edge devices have S3 and EC2 compatible endpoints available, enabling programmatic use cases.
• Customers who need to run Amazon EC2 workloads on AWS Snowball Edge devices can attach multiple persistent block storage volumes to their Amazon EC2 instances.
• For latency-sensitive applications such as machine learning, you can deploy a performance-optimized SSD volume (sbp1). Performance optimized volumes on the Snowball Edge Compute Optimized device use NVMe SSD, and on the Snowball Edge Storage Optimized device, they use SATA SSD. Alternatively, you can use capacity-optimized HDD volumes (sbg1) on any Snowball Edge.

Job Types

• Import To S3 – transfer of 80 TB or less of your local data copied onto a single device, and then moved into S3.
  • Snowball Edge devices and jobs have a one-to-one relationship. Each job has exactly one device associated with it. If you need to import more data, you can create new import jobs or clone existing ones.
• Export From S3 – transfer of any amount of data located in S3, copied onto any number of Snowball Edge devices, and then move one Snowball Edge device at a time into your on-premises data destination.
  • When you create an export job, it’s split into job parts. Each job part is no more than 100 TB in size, and each job part has exactly one Snowball Edge device associated with it.
• Local Compute and Storage Only – these jobs involve one Snowball Edge device, or multiple devices used in a cluster. This job type is only for local use.
  • A cluster job is for those workloads that require increased data durability and storage capacity. Clusters have anywhere from 5 to 10 Snowball Edge devices, called nodes.
  • A cluster offers increased durability and increased storage over a standalone Snowball Edge for local storage and compute.

Recommendations

• Files should be in a static state while being written to the device.
• The Job created status is the only status in which you can cancel a job. When a job changes to a different status, it can’t be canceled.
• All files transferred to a Snowball be no smaller than 1 MB in size.
• Perform multiple write operations at one time by running each command from multiple terminal windows on a computer with a network connection to a single Snowball Edge device.
• Transfer small files in batches.

AWS Snowball Edge Security

• All data transferred to a device is protected by SSL encryption over the network.
• To protect data at rest, Snowball Edge uses server side-encryption.
• Access to Snowball Edge requires credentials that AWS can use to authenticate your requests. Those credentials must have permissions to access AWS resources, such an Amazon S3 bucket or an AWS Lambda function.

AWS Snowball Edge Pricing

• You are charged depending on the type of Snowball Edge machine you choose (storage optimized or compute optimized).
• You are charged based on what you select for your term of use: On demand, a 1-year commitment, or a 3-year commitment.
• For on-demand use, you pay a service fee per data transfer job, which includes 10 days of on-site Snowball Edge device usage. Shipping days, including the day the device is received and the day it is shipped back to AWS, are not counted toward the 10 days. If the device is kept for more than 10 days, you will incur an additional fee for each day beyond 10 days.
• There is a one-time setup fee per job ordered through the console.

AWS Snowball Edge Limits

• Each data transferred must have a maximum size of 5 terabytes.
• Jobs must be completed within 120 days of the Snowball Edge device being prepared.
• The default service limit for the number of AWS Snowball Edge devices you can have at one time is 1.
• If you allocate the minimum recommendation of 128 MB of memory for each of your functions, you can have up to seven Lambda functions in a single job. (Limited because of physical limits)
