3 ways to move data to the cloud

Answer 1

• Internet
• Direct Connect
• Physical devices

Question 2

Using Internet to move data to cloud

Answer 2

• can use existing internet connection
• very slow
• security risk

Question 3

Using Direct Connect to move data to cloud

Answer 3

• faster and more secure

- not practical if it’s not needed after the migration

Question 4

Snow Family

Answer 4

Provides

• migration of large-scale data
• data collection and processing at the edge

Question 5

Snow Cone

Answer 5

• 8 TB storage
• 4 GB memory
• IoT sensor integration
• perfect for edge computing where space and power are constrained *

Question 6

Snow Ball & Snow Ball Edge

Answer 6

• perfect for Terabytes (48-81 TB of storage)
• pick for scenarios with slow internet connection or needing secure, encrypted data
• storage, compute and GPU flavors
• varying amounts of CPU and RAM
• perfect for off-grid computing or an AWS migration*

Question 7

Snow Mobile

Answer 7

• 100 PB of storage
• designed for exabyte-scale data
• big escorted truck

Question 8

What is the turnaround time for snow family?

Answer 8

about a week

Question 9

What is Storage Gateway?

Answer 9

• a hybrid cloud storage service that lets you merge on-prem resources with the cloud
• specifically it’s a vm that you run in your data center
• can be used for a one-time migration, or a long-term pairing of your on-prem architecture with AWS

Question 10

File Gateway

Answer 10

• NFS or SMB Mountain which an be mounted locally and it backs up all of your data in S3
• Can keep a local copy of recently used files (cached)

Question 11

What’s a good use case for File Gateway?

Answer 11

when on premise users don’t have enough on-prem storage space. *

Question 12

Volume Gateway

Answer 12

• iSCSI mount
• cached or stored modes
• create EBS snapshots
• perfect for backup or migration

Question 13

Tape Gateway

Answer 13

• replaces physical tapes
• tricks devices into thinking they are backing up to a tape, when they are actually backing up to the cloud (Glacier or Glacier Deep Archive)
• integrated as a VM on prem*

Question 14

AWS Data Sync

Answer 14

• an agent based solution for migrating on prem to AWS
• secure via TLS
• good for a one-time migration
• can dump to FSx or EFS

Question 15

Why would you choose Storage Gateway over AWS Data Sync?

Answer 15

If you want to keep using it after the migration is finished

Question 16

AWS Transfer Family

Answer 16

• allows you to easily move files in/out of S3 or EFS using SFTP or FTP over SSL or FTP
• tricks legacy users into thinking they are writing to their old endpoints when they are actually hitting S3 cloud storage*

Question 17

Migration Hub

Answer 17

a single place to track the progress of your application migration to AWS
- an organization tool

Question 18

Server Migration Service

Answer 18

• lets you take your VCenter/VSphere data center architecture and convert it to an AMI
• lets you schedule when each vSphere gets converted to an AMI, which can in turn launch an EC2 instance
• NOTE: exam treats the Migration Services as magic

Question 19

Database Migration Service

Answer 19

• takes an old oracle DB or SQL Server or MySQL BD on-prem and converts it to Aurora DB
• can be used to consolidate multiple databases into one database

Question 20

4 migration questions to ask yourself during the exam

Answer 20

1) where are we going (to what region)? what does the architecture look like? do we need to look back at the old data center?
2) how do we get there? do we want a hybrid permanent solution?
3) do we do it all at once?
4) Is it a full or partial migration?

Question 21

What are the benefits/pitfalls of migrating all at once?

Answer 21

• simpler
• will have downtime
• will we meet our uptime SLAs?
