A

1) Snowcone
2) Snowball Edge
3) Snowmobile

23
Q

The 2 Snow Family devices for Edge computing are

A

1) Snowcone
2) Snowball Edge

24
Q

Snowball Edge is a

A
  • Physical data transport solution: move TBs or PBs of data in or out
    of AWS
  • Alternative to moving data over the network (and paying network
    fees)
  • Pay per data transfer job * Provide block storage and Amazon S3
    -compatible object storage
25
Q

A

80 TB of HDD capacity for block volume and S3 compatible object
storage

26
Q

Snowball Edge Compute Optimized provides

A

42 TB of HDD or 28TB NVMe capacity for block volume and S3
compatible object storage

27
Q

AWS Snowcone & Snowcone SSD are

A
  • Small, portable computing, anywhere, rugged &
    secure, withstands harsh environments
  • Light (4.5 pounds, 2.1 kg) * Device used for edge computing, storage, and data
    transfer
    and
  • Can be sent back to AWS offline, or connect it to
    internet and use AWS DataSync to send data
28
Q

The Snowcone provides

A

8 TB of HDD Storage

29
Q

The Snowcone SSD provides

A

14 TB of SSD Storage

30
Q

AWS Snowmobile allows for

A
  • Transfer exabytes of data (1 EB = 1,000 PB = 1,000,000 TBs)
  • Each Snowmobile has 100 PB of capacity (use multiple in parallel)
  • High security: temperature controlled, GPS, 24/7 video surveillance
  • Better than Snowball if you transfer more than 10 PB
31
Q

Snow Family – Usage Process

A
  1. Request Snowball devices from the AWS console for delivery
  2. Install the snowball client / AWS OpsHub on your servers
  3. Connect the snowball to your servers and copy files using the client
  4. Ship back the device when you’re done (goes to the right AWS
    facility)
  5. Data will be loaded into an S3 bucket
  6. Snowball is completely wiped
32
Q

What is Edge Computing?
