I was talking about "in a datacenter", but yes, you have almost zero elasticity with datacenter buildouts. You can get metered power but that can be a mixed bag since its usually more expensive per KWH. Most companies that "move to the cloud" also make a lot of changes to the way they do things so they can scale/up down dynamically, thats not an insignificant cost in development time. If you have a static load AWS is really expensive. Also GPU's are still insanely bad to do in AWS/Azure. Lets say you need the equivalent of 60 x p3.16xlarge for a whole year, thats well over a million USD a month. You're breakeven on month 3 in a datacenter even with all the overhead. Maybe some of that is my ability to get good deals, but even if you breakeven on month 4, thats crazytown.

>> If you have a static load, AWS is really expensive. Again without details, this a meaningless claim. My own company's only infrastructure is a website that "runs" on AWS using the free tier of Cloudfront and a little bit of the paid tier of S3. This is a static workload. It is really cheap. Without adding all the details on both sides and the workload you cannot claim that AWS (or for that matter any cloud vendor) is more expensive.

  If you can find cases where its cheap, thats great, but its not the case for a lot of people with static compute load. One of my example datacenters is: Private servers, access controlled, etc 12 servers (E5-2438L, 128GB of ram, 6T of RAID in each, 10gbps interconnects/etc) It costs $1200/month to run. Just the storage cost in AWS is around $3k/monthly. The equivalent EC2 cost is around $14k/monthly. It requires around 1-2 hours/month of oversight and the costs are generally fixed except for the bandwidth which is billed at a fraction of the cost of AWS pricing.
