Sizing for this kind of deployment was a lot of fun! We went ahead with- 5x Ingestors, each with 64 vcpu 128 GB

5x Queriers, each with 64 vcpu 192 GB

The current utilization sits comfortably at 10-15 vcpu and 20-30 GB memory for the ingestors 20-40 vcpu and 40-60 GB memory for the queriers

Ample of headroom for transient spikes and planned near-future growth
