Storage gateway

hybrid cloud for storage

Overview

• Bridge between on-premises & cloud

  

  hybrid cloud for storage
• Providing low-latency access to data by caching frequently accessed data on-premises while storing archive data securely and durably in Amazon cloud storage services.

4 types

S3 file gateway

S3 File Gateway

• S3 buckets are accessible using NFS & SMB protocols.

• Most recent used data are cached in the file gateway.

• Bucket access using IAM role for each file gateway

• SMB protocol is integrated with AD (Active Directory) for user authentication.

FSx file gateway

native access for Window File Server

• Local cache for frequently accessed data.

• Window native compatability (, NTFS, AD...)

Volume gateway

block storage using iSCSI protocol

• Block storage using iSCSI protocol backed by S3.

  • Stored volume: stores the entire data set on-premises and asynchronously backs up the data to AWS.

  • Cached volume: stores recently accessed data on-premises, and the remaining data is stored in Amazon S3.

• Backup: using this can backup on-prem data using EBS volume

Tape gateway

tape gateway backed by S3 & Glacier

• Virtual Tape Library (VTL) backed by using S3 and Glacier.

• Backup data using tape-based process (iSCSI protocol)

Use cases

• Disaster recovery

• Backup & restore

• On-prem cache & low latency file access
