Why did your companies have to rely on Nebius for gigantic contracts for AI/Cloud infrastructure? (Isn't this something that MSFT and META can easily do on thier own? Just like AMZN with AWS?) What does Nebius do so uniquely? My non deep dive shows Nebius ad the only infrastructure provider that has vertical integration? Is this verticality THAT coveted ? Also, are these only short term rentals (5 years) until Microsoft and Meta simply just build their in-house infrastructure?
