Migration Flashcards
What are the 3 types of physical data transfers for AWS migrations?
- Snow cone
- Snowball
- SnowMobile
What is the storage size for SnowCone? What special features does it have?
- 8TB
- It is small, and has IOT integration
- Good where compute and space is limited
What is storage size for Snowball? What special features does it have?
- 50TB to 80 TB
- Compute,GPU,Storage types
- Good for offgrid or one time migrations to AWS
What is Snowmobile?
- 100PB
2. Truck for exbyte scale
Can you transfer data out of AWS and shipped back to you using Snow?
Yes you can
What is Storage Gateway?
A hybrid cloud storage, merging on-prem with cloud for ongoing or onetime needs
What is File Gateway?
SMB/NFS based fileshare that backs up into S3.
What are the 2 modes of File Gateway?
- stored mode: Keep all files on the cloud
2. cached mode: Keep most recently used files cached on-prem with files backed up to S3
What should your solution be if your users dont have enough on-prem file storage space?
Solution is to use File Gateway cached
What is Storage Gateway when it is installed on-prem?
They are AWS provided VM’s running on the on-prem
What is Volume Gateway?
iSCi based backup onprem VM’s disks to the cloud
Where does Volume Gateway back up to? What can you do with that data after?
Stores into S3, where you can create EBS snapshots/volumes from the disks
What are the 2 modes of Volume Gateawy?
- stored mode
2. cached mode
What is Tape gateway?
Replace physical tapes and stores into the cloud e.g. in Glacier
What does Storage Gateway help with?
Helps migrate on-prem resources to the cloud or extend on-prem storage
What is DataSync?
Agent based solution for migrating data from on-prem to the cloud for NFS/SMB fileshares
When should you use DataSync?
When you want to do one time migrations of large chunks of data of fileshares
What 3 target storage services does DataSync support?
EFS,Fsx, S3
When should you use Storage Gateway over DataSync?
When you want ongoing sync to the cloud with a hybrid architecture vs. a one time migration lift and shift
Will you have to install an agent for DataSync?
Yes you will need and agent on-prem
What is AWS Transfer Family?
Services allowing transfer of file in and out of S3/EFS using FTP and SFTP, FTPS
Does AWS Transfer Family support transfer over the public internet?
Only for Secure FTP. Regular FTP can only be done within the AWS environment
When should you use AWS Transfer Family? How?
When you have a legacy application but need to have storage on S3/EFS, just swap out the DNS
What are reasons to use AWS Snow?
- Slow internet speeds
- Secure transfer requirements to not go over public
- DIrect Connect is costly and takes time to setup, not just for a one time migration
