A research team conducting its work in remote locations of the world, without internet access, wishes to leverage Amazon services for their storage. The team collects petabytes of information at a time. Which service will best meet to transfer the petabytes of information?

Answer options:

A.Amazon S3
B.Amazon Elastic Block Store (EBS)
C.Amazon S3 Glacier
D.AWS Snowball

Correct Answer – D
The AWS Snowball service uses physical storage devices to transfer large amounts of data between Amazon Simple Storage Service (Amazon S3) and your onsite data storage location at faster-than-internet speeds. By working with AWS Snowball, you can save time and money. Snowball provides powerful interfaces that you can use to create jobs, track data, and track your jobs` status through to completion.
Snowball devices are physically rugged devices protected by the AWS Key Management Service (AWS KMS). They secure and protect your data in transit.

Option A is incorrect because Amazon S3 is the most suitable object storage when there is internet connectivity. In this scenario, there is none.
Option B is incorrect because Amazon EBS provides block level storage volumes suitable for operating systems, database instances and applications. For the research team to store data to detached EBS volumes (not attached to EC2 instances), they would need internet connectivity. In this scenario, the remote location does not have connectivity.
Option C is incorrect because S3 Glacier is used for infrequent access nor usage. It is unsuitable for this scenario.
