tiered storage
on-premise cache & low-latency file access

47
Q

Different Kinds of Storage Gateways

A

S3 File Gateway
FSx File Gateway
Volume Gateway
Tape Gateway

48
Q

S3 File Gateway architecture

A

1 Corporate Data centre & AWS Cloud

You have your app server on-prem and you add an S3 File Gateway.

In the cloud you have your bucket (s3 standard, standard IA, One Zone IA, INtelligent-Tiering) and a Lifecycle policy for S3 Glacier .

Then you transfer data through HTTPS from cloud and on-prem.

Protocol used is NFS or SMB

SMB protocol has integration with AD for user auth

Frequently accessed data are cached

49
Q

FSx File Gateway

A

Native access to Amazon FSx for Win File Server

Local Cache for frequently accessed data

Native compatibility with SMB, NTFS, AD

useful for group file shares and home directories

50
Q

FSx File Gateway Architecture

A

SMB client and FSx File Gateway on-prem. Amazon FSx for WIndows File Server in AWS Cloud.

51
Q

Main reason to use FSx File Gateway?

A

Local Cache for frequently accessed data

52
Q

Volume Gateway

A

Block storage using iSCSI protocol backed by S3

53
Q

What does Volume Gateway do?

A

Backed by EBS snapshots which can restore on-prem volumes

Cached Volumes - low latency access to most recent data

Stored Volumes - entire dataset is on prem, scheduled for backup to S3

54
Q

Volume Gateway architecture

A

App server in on prem data centre. You also have a Volume Gateway and connect both with iSCSI interface.

The gateway contacts via HTTPS the S3 Bucket in the cloud which also contacts the Amazon EBS Snapshots (all in the cloud)

55
Q

Why do you want to use Volume Gateway

A

To backup your on-prem volumes

56
Q

Tape Gateway

A

Backup for physical tapes in the cloud

57
Q

What is Tape Gateway using?

A

Virtual Tape Library (VTL) backed up by S3 and Glacier

58
Q

Tape Gateway Architecture

A

On prem - Backup server, iSCSI interface chooses media changer or tape drive. Then the tape gateway connects via HTTPS to the cloud.

Directly onto the S3 that stores Virtual TApes, and also the archived tapes stored in amazon glacier

59
Q

What is Storage Gateway - Hardware appliance?

A

Essentially a mini server that can be installed on prem and act as a file, volume, tape gateway.

Can be ordered if you do not own any physical gateways

60
Q

When is a Storage Gateway - Hardware Appliance useful?

A

For daily NFS backups in small data centres

61
Q

AWS Transfer Family

A

File transfers into and out of Amazon S3 or EFS using FTP (only)

62
Q

AWS Transfer Family protocols

A

FTP
SFTP
FTPS

63
Q

Benefits of Transfer Family

A

Managed infrastructure
Scalable
Reliable
HA (multi az)

Pay per endpoint per hour

store and manage users credentials within the service

64
Q

Transfer Family use cases

A

sharing files
public datasets
CRM
ERP

65
Q

AWS Transfer Family Architecture

A

User using FTP client goes through Route 53 (optional) to SFTP, FTPS, FTP (VPC only) and using an IAM role they can connect to S3 or EFS.

users can also be auth using LDAP or MS AD.

66
Q

AWS DataSync

A

Move large amounts of data to and from
- on prem or other cloud to AWS - needs agent
- AWS to AWS (no agent needed)

Can synchronise - S3, EFS, FSx (win, lustre, NetApp, OpenZFS)

Scheduled Replication (hourly, daily, weekly)

File permissions and metadata are preserved (NFS POSIX, SMB)

One agent can task 10Gbps, can have bandwidth limit

67
Q

DataSync Architecture

A

NFS or SMB server on prem. connects to DataSync Agent which allows connection over TLS to AWS DataSync in the cloud. Then from there you can transfer/sync data to any AWS Storage Resources. Can also transfer and sync data from AWS to on prem.

68
Q

DataSync - what happens if you want to use it but do not have the bandwidth?

A

You can use AWS Snowcone because it has the DataSync agent pre-installed. Upload the data, run the agent, ship it to AWS and the Sync will happen there.

69
Q

Can you use AWS DataSync for transferring between AWS storage devices?

A

Yes - you can transfer directly between S3, EFS, FSx. And keeps the metadata

70
Q

What can you use to preserve metadata and file permissions when you do a transfer between storage services?

A

AWS DataSync

71
Q

What do you need to run to be able to connect and transfer data to NFS or SMB server?

A

DataSync Agent

72
Q

S3

A

Object Storage

73
Q

A

Network File System for Windows Servers

78
Q

FSx for Lustre

A

High performance Computing Linux file system

79
Q

FSx for NetApp ONTAP

A

High OS compatibility

80
Q

FSx for OpenZFS

A

Managed ZFS file system

81
Q

Storage Gateway

A

S3 & FSx File Gateway, Volume Gateway (cache & stored), Tape Gateway

81
Q

Storage Gateway

A

S3 & FSx File Gateway, Volume Gateway (cache & stored), Tape Gateway

82
Q
