AWS Service - Storage Gateway

Storage Gateway

Premise
- Hybrid Cloud for Storage
- AWS have been pushing for ”hybrid cloud”
  - Part of your infrastructure in “on cloud” and “on premise”
- This can be due to
  - Long cloud migrations
  - Security requirements
  - Compliance requirements
  - IT strategy
- To help with this came AWS Storage Gateway
Overview
- Bridge between on-premises data and cloud data
- Types of Storage Gateway
  - S3 File Gateway
  - FSx File Gateway
  - Volume Gateway
  - Tape Gateway
- Use cases
  - DR; Backup and restore; Tiered storage; on-premise cache and low latency file access
AWS Storage Cloud Native Options
- Block - EBS ; EC2 Instance store
- File - FSx ; AWS EFS
- Object - S3; Glacier

Amazon S3 File Gateway
- Configured S3 buckets are accessible using the NFS and SMB protocol
- Most recently used data is cached in the file gateway
- Supports S3 Standard, S3 Standard IA, S3 One Zone A, S3 Intelligent Tiering
- Transition to S3 Glacier using a Lifecycle Policy
- Bucket access using IAM roles for each File Gateway
- SMB Protocol has integration with Active Directory (AD) for user authentication

Amazon FSx File Gateway
- Native access to Amazon FSx for Windows File Server
- Local cache for frequently accessed data
- Windows native compatibility (SMB, NTFS, Active Directory, etc)
- Useful for group file shares and home directories

Amazon Volume Gateway
- Block storage using iSCSI protocol backed by S3
- Backed by EBS snapshots which can help restore on-premises volumes
- Cached volumes: low latency access to most recent data
- Stored volumes: entire dataset is on premise, scheduled backups to S3

Amazon Tape Gateway
- Some companies have backup processes using physical tapes
- With Tape Gateway, companies use the same processes but, in the cloud
- Virtual Tape Library (VTL) backed by Amazon S3 and Glacier
- Back up data using existing tape-based processes (and iSCSI interface)
- Works with leading backup software vendors

Storage Gateway - Hardware appliance
- Using Storage Gateway means you need on-premises virtualization
- Otherwise, you can use a Storage Gateway Hardware Appliance (You can buy it on amazon.com)
- Works with File Gateway, Volume Gateway, Tape Gateway
- Has the required CPU, memory, network, SSD cache resources
- Helpful for daily NFS backups in small data centers
