Amazin S3

Simple Storage Service (S3) is an object storage service from AWS. It can not only service objects through a CDN to CloudFront, manage access to specific objects, enable versioning, and lifecycle policies, but it can also serve static HTML files with Route 53. It is a simple key-value store designed for unlimited object storage.

  • Designed for “11 nines” (99.999999999%) durability and 99.99% “availability”
    • Charges based off per gig storage as well as data sent out of the region
    • Data transfer from S3 to an EC2 instance within the same region is free
    • Cost decreases as it scales
  • S3 objects can be encrypted using the S3 encryption option as well as data sent to and from endpoints are encrypted using HTTPs protocol.
  • Most commonly used for file storage (is also a hybrid solution when used AWS Storage Gateway), delivering static content, backups and archiving with Amazon Glacier.
  • Bucket names are unique across the entire S3 design (all regions included)
  • RRS (Reduced Redundancy Storage)
    • Cost effective
    • Only for “easily reproducible data”
    • 99.99% durability vs “eleven nines” for standard storage type
  • Lifecycle policies and object versioning
    • Pay for each version of the object
    • Unlimited versions
    • Needs to be enabled
    • Versioning and lifecycle policies can work together for an automated backup and archiving solution
    • Lifecycle policies with Amazon Glacier

Amazon Glacier

  • Archival storage type
  • Used for data not frequently accessed
  • Check out and check in jobs can take several hours for the data to be changed
  • Integrates with Amazon S3 lifecycle policy for easy archiving
  • .01/gig per month

Amazon Storage Gateway

Connect local center software appliance to cloud-based storage such as Amazon S3

Gateway-Cached Volumes

  • Create storage volumes and mount them as ISCSI devices on-the-premises servers
  • The gateway will store the data written to this volume in Amazon S3 and will cache frequently access data on-premise in the storage devices

Gateway-Stored Volumes

  • Stored all the data locally in storage volumes
  • Gateway will periodically take snapshots of the data as incremental backups and stores them on Amazon S3

Amazon Import/Export

AWS Import/Export gives the ability to take on-premise data and physically snail mail it to AWS. AWS will import/Export the data to either S3, EBS, or Glacier within one business day of the physical device arriving at AWS.


  • Off-site backup policy
  • Quickly migrate LARGE amounts of data to the cloud
  • Disaster recovery (AWS amounts of data to the cloud
