Hi Cara,

We have four Shibboleth IDPs in production – two for general UK Federation stuff and two for Office365 Federation. All four are Linux (RedHat in our case) VMs with 1 vCPU each and 2G RAM (Office365 IDPs have 4G).

The UK Federation facing servers see between 1,000 and 4,000 authentications per day (and currently have about 30G of logs for 3 months) while the Office365 facing ones, as Cal has already point out :), see about 450,000 per day.

That being said, we're starting to see some issues with our backend LDAP instances not being able to cope with the start-up load after an outage ;-)

Hope that helps,
--
