  • The lab maintains an instance of the Real Data Corpus on AWS Govcloud.

Initial State

  • The RDC is stored in an S3 bucket.
  • This meets the objective of keeping a copy in a location where it could be shared with NPS research partners and approved affiliates.
  • A limitation is that VMs cannot compute directly on data in the S3 buckets without first moving them.

Transition to EBS

  • AWS offers an Elastic Block Storage service, which closely approximates the capabilities of a physical Storage Area Network.
  • Snapshots of EBS devices can be saved to S3 buckets.
  • It may be better to keep snapshots of an EBS in S3 that the corpus images themselves.

Creating an EC2 Instance and Logging On
