We'd hire the initial deployment out to temporary contractors. It just took a few weeks to get a large deployment out. The hard part was the 12 GPUs needed to be inserted at the DC, which took a bunch of effort. Once it was done we generally had 1-2 people on the ground in the data centers to deal with breakfixes. Either contractors or supplied by the DC.
For this venture, again, we are starting small, so we are just flying to the DC and doing it ourselves. There are also staff there that are technical enough to swap stuff out when we need it. The plan will be to just hire one of their staff as our own.
I don't think we will make it for this next deployment due to time constraints, but ideally in our near future, we will go full L11. Assemble and ship out full racks at the manufacturer/VAR, bolt em down, wire them up and ready to go. That is my dream... we will see if we get there. L11 is hard cause a single missing cable can hold up an entire shipment.
