- Edge Location: this is the location where content is cached and can be used to write too. Separate to an AWS Region/Az. Actually, there are more Edge Locations than AWS regions. EdgeLocation cached files from the origin speeds up delivery to videos, images, etc. Used for S3 Transfer Acceleration.
- Origin can be S3 Bucket, EC2 Instance, ELB or Route53
- Distribution: the name was given to our CDN
- Web distribution: typically used for websites
- RTMP: Used for media streaming
- All data transferred between any type of gateway appliance and AWS storage is encrypted using SSL.
- By default, all data stored by AWS Storage Gateway in S3 is encrypted server-side with Amazon S3-Managed Encryption Keys (SSE-S3).
- Also when using the file gateway, you can optionally configure each file share to have your objects encrypted with AWS KMS-Managed Keys using SSE-KMS.
File Gateway (NFS): Flat files in S3, pdfs, pictures, videos,(stored in S3)
Volume Gateway (iSCSI): virtual hard disk
Stored Volumes: entire copy of dataset is stored on site and is backup async to S3.
Cached Volumes: entire dataset is stored on S3 and the most frequently accessed data is cached on site.
Gateway-Virtual Tape Library (VTL): backup, create virtual tapes and send to S3.
File Gateway (NFS)
Volume Gateway (iSCSI)
Virtual Hard Disks presented at on-premises via iSCSI and you backup them to S3. Data written to these volumes can be asynchronously backed up as point-in-time snapshots of your volumes and stored as EBS snapshots. Snapshots are incremental.
Let you store your primary data locally while asynchronously backing up that data to AWS. Low latency access to their entire datasets, with durable backups. Data written to your stored volumes is stored on your on-premises storage hardware. This data is backed up to AWS S3 in the form of EBS Snapshots.
