Peak Utilization is a tough one for on prem and is a decent argument for cloud. I was at a company that was also at <10% peak utilization most of the time. It was finance, so it was mostly doing nothing, except for the couple days a year where we shot up 10000x, so we had to build for that case. So yeah losing the data centers, and cloud was a cost savings.
- senderista 1y agoSo the "obvious" (but complex!) solution is a "hybrid cloud": use on-prem for the predictable, constant "DC component" of your demand, and use cloud for cyclical or unpredictable demand changes. That will keep peak demand decoupled from permanently provisioned capacity while saving on always-utilized capacity. Easier said than done, of course.
- ecshafer 1y agoThe route we ended up going, was hybrid cloud with a colocation for on-prem (Mainframes and a few servers), and then AWS for the cloud portion. Not sure on what the cost savings were. As I wrote the authentication service I knew what those numbers were, so I knew that on a normal day we would be sitting at 1% cpu usage basically all day except market open/close. And then fiscal quarter ends were a big bump. And then of course big news days. 99% of the time for 99% of the days were just nothing.
