The main production IDR consists of 6 servers:

• Database (6 CPUs/32GB RAM): A dedicated PostgreSQL server .
• OMERO read-write (4 CPUs/16GB RAM): Internal OMERO.server and OMERO.web with a highly customised configuration optimised for the data access patterns of the IDR.
• OMERO read-only (4 CPUs/32GB RAM): 2 public read-only OMERO.server and OMERO.web with a highly customised configuration optimised for the data access patterns of the IDR.
• Search engine (4 CPUs/16GB RAM): A dedicated Elasticsearch server for search functionality.
• Proxy: Front-end proxies that manage all public access to the IDR. Nginx load-balances all public web access and incorporates an aggressive caching configuration to reduce the load on OMERO. Haproxy load-balances access to the OMERO API.
