Section 16: AWS Storage Extras Flashcards
What is the AWS Snow Family?
The Snow family is a collection of physical, off-line devices that collect and process data at the edge. They help migrate large amounts of data into and out of AWS without needing a network
When should you use Snowball devices?
Snowball devices should be used if it takes over a week to transfer data via a netwrok
What is Snowball Edge?
Snowball edge is a physical data transport solution with storage and compute optimized versions. Snowball edge allows you to pre-process data while its being moved, and is used for large data cloud migration, disaster recovery, and data center decommissioning
What is Snowball Snowcone?
Snowcone is a small, portable computer meant for anywhere (rugged and secure). Mostly useful for where Snowball cannot go.
What is Snowball Snowmobile?
SnowMobile is meant for transferring massive amounts of data, and is highly secure (video surveillance, temp control, gps etc.
What are three (3) main use cases of edge computing?
1) pre-processing of data while its being created
2) Machine learning at the edge
3) Transcoding media streams
How do you import Snowball into Glacier?
Snowball cannot import directly into Glacier. Snowball data must be imported into an S3 bucket with a lifecycle policy first.
What does Amazon FSx do?
Amazon FSx allows us to launch 3rd party high-performance file systems on AWS.
What does Amazon Storage Gateway do?
Amazon Storage Gateway connects on-premises software appliances to AWS. This allows us to bridge between on-premises data and cloud data using S3.
What is Hybrid Cloud, and why is AWS pushing it for storage?
Hybrid cloud is when part of infrastructure in on the cloud and part is on-premises. AWS is pushing for this due to long cloud migrations & security / compliance requirements.
What are the three (3) main use cases of AWS Storage Gateway?
1) Disaster Recovery
2) Backups
3) Restoring data
What are the three (3) types of Storage Gateways?
1) File Gateway
2) Volume Gateway
3) Gateway Virtual Tape Library
How does the File Gateway work?
The File Gateway stores files as objects in S3, and then accesses them using NFS mount point. It caches recent files, and is integrated with AWS Active Directory (AD) for user authentication.
What is the goal / purpose of the File Gateway?
File Gateway’s goal: To help expand the size of an on-premises NFS by leveraging S3 with user authentication
How does the Volume Gateway work?
The volume gateway stores an entire dataset in S3, and saves snapshots in EBS. It offers Stored volumes (entire data volume is locally available) and Cached volumes (giving low-latency access to frequently used data)
