> Back in the dotcom days companies would spend a fortune on Sun kit but I bet when averaged out over time a comparable company would be spending a LOT more on cloud billing. I would like to learn more about this. I'd have thought costs should go down over time. Are we doing more or is the cost per unit (not sure what that means) is truly going up?
When was the last time a landlord reduced your rent? You always can drive cost concessions from sales, especially for base workloads where you have time flexibility. For a big company, cloud rarely saves money for many categories of expense. In a normal market, it is almost always faster time to market to rent, and always cheaper TCO to own.
This is a different market and one which is ultimately constrained by the availability of land. Notably, cloud prices do fall especially relative to the compute power. Specifically I remember when Fargate moved to firecracker and prices fell by like 40% or something similarly considerable.
Maybe managing your own internal cloud is indeed cheaper (especially if you don't account for support or maintenance!), but arguing that cloud prices don't decrease or making some housing analogy seems like poor reasoning.
