S3, EFS and FSx

Question 6

What service provides offline data migration?

Snow Family

Question 7

What is edge computing and what storage solution in AWS and parts of it provide edge computing?

Answer 7

Processing data close to the source of the data. This can be achieved either using networking solutions that bring the data close to source or for storage using hardware such as Snowcone and Snowball Edge part of the Snow Family service

Question 8

What specific service should be used for a offline data migration of >10 Pb?

Snowmobile

Question 9

What is the difference between object, file and block storage?

Answer 9

Objects are not stored in folders, are all at the same level and are accessed using a object key instead of file path and though an API.
File storage uses a file path to access typically consisting of folders and the data is stored with a file extension dependent on the file type and accessible though different applications.
Data is split into blocks of equal size each block is assigned a unique id and blocks can be assigned to different OS environments

Question 10

What are the use cases for EBS?

Answer 10

Used for data requiring quick access, long-term persistence and continuous reads and writes. Attaches to instances work as a hard drive. Works a more permanent solution to EC2 instance store

Question 11

What are the use cases for S3?

Answer 11

Storing and managing large amounts of unstructured data, such as images and videos, backups, and other types of data that can be accessed via the internet

Question 12

What are the use cases for EFS?

Answer 13

Like EFS except desire access to a 3rd party file storage system

Question 14

What is the difference between durability and availability?

Answer 14

Durability is how much well data is retained and availability is how much a service crashes

Question 15

What are the S3 storage classes and there use cases?

Answer 15

Standard - gen purpose: typically frequent access
Standard IA: IA but needs millisecond access
One zone IA: IA needs millisecond access lower availability so either as backup or data is easy to recreate
Glacier Instant Retrieval: min 90 day storage, accessed once a quarter, requiring millisecond retrieval
Glacier Flexible Retrieval: min storage 90 days
- expedited (1-5 mins retrieval)
- standard (3-5 h)
- bulk (5-12 h)
Glacier Deep Archive: min storage 180 days
- standard (12 h)
- bulk (48 h)
Intelligent Tiering: unknown or changing access patterns
