OpenStack and IDR Ansible Playbooks

The main production IDR consists of 7 servers:

• Database (8 CPUs/32GB RAM): A dedicated PostgreSQL server .
• OMERO read-write (16 CPUs/64GB RAM): Internal OMERO.server and OMERO.web with a highly customised configuration optimised for the data access patterns of the IDR.
• OMERO read-only (8 CPUs/32GB RAM): 4 public read-only OMERO.server and OMERO.web with a highly customised configuration optimised for the data access patterns of the IDR.
• 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.

The IDR deployment GitHub repository contains Ansible playbooks and full instructions for provisioning resources and deploying the IDR, as well as our internal operating procedures.
