I 100% agree, unfortunately the reality is that it is just not possible...yet. We have projects where the C suite has demanded a cloud transition and a move from Oracle and every single one has been a disaster. The highest tier iops Azure offers is not enough to cover our smallest medium customer. Believe me, I have been working with Oracle since v7. You will be hard pressed to find someone that dislikes Oracle more than me and I pray for the day they go away or have a massive shift like MS has. But, as it relates to SUSE's growth as a RHEL replacement, Oracle is and will likely continue to be a deterrent. I hope I am wrong because even though I started my Linux journey with Red Hat Halloween, they too have lost me.
Azure has had nvme drives with hundreds of thousands of iops for a couple of years. That plus sharding should take care of any problems. I have personally taken care of a project with 2M tps and it wasn't even the biggest in my region, at the small-ish company I work for. Yes, re-architecting that is a pain but doable.
Lift and shift may be out of the question tho.
That and cost are the real issue. This is not their app, so they cannot rearchitect it. To make it fit to best use cloud resources, the thing would need to be rebuilt from scratch, and the savings are just not there to do so.
We need to move 8 gigabytes per second, sustained, which Azure can do at their highest tier. The problem is that, as I said, this is the smallest of our medium clients, and at the tier that can sustain that, the cost per terabyte per month is well beyond the client's budget. We told them to go with Exadata but the initial sticker shock and the execs lack of faith on their IT team made them run. Now they are committed to Azure. Just last week we had that call where we told Azure our requirements and they just came back with the price a few days ago. Suddenly, dropping seven figures for the hardware doesn't seem too expensive.
Whatever. We get paid either way.
