EHRI System Administration

These documents describe the current state of system administration for the EHRI sites as of February 2018.


EHRI uses cloud VPS systems provided by Digital Ocean, primarily because DO provide servers based in the Netherlands, which was a requirement for EHRI data.

DO provide team administration for servers, so if your require access ask to be added to the EHRI team.

File Storage

EHRI currently uses AWS S3 for hosting certain data:

  • some static assets for the EHRI portal, along with uploadable data such as user profile images
  • Omeka media, via the S3 FileStorage Adapter plugin
  • Database backups

We principally use the eu-central-1 region to keep data on European servers.

As of 2021 we also use Digital Ocean's Spaces storage service, via its S3-compatible API, for storing file-based metadata for ingest into the portal. These spaces are based in the AMS3 (Amsterdam) data centre.

Ask a member of the EHRI team for access to AWS or DO resources.
