Architecture preconisation for a datacenter plateform with 10 000 users (with high availability)

[Foucault Dupleix]

Hello,

We are going to setup a new plateform with around 10 000 users for both Jira and Confluence usage.

The plateform will be very critical, so we would like to use The Datacenter setup.

We searched for some preconisation in term of number and size of VM for nodes, for database, etc.

Can you please provide some guidance for this kind of setup ?

Regards,

Foucault
