Spot on. I have a lot of trouble convincing cloud folks that for durable state, you probably don’t want kubernetes. It’s not that e.g. the CSI drivers and operators for clustered databases aren’t top notch—they are; the era of “avoid stateful kube services” is long behind us—it’s that the cloud provider managed services for e.g. blob stores or databases are so much more reliable. The S3s and Auroras of the world are expensive for a reason: no matter how good your kube native database operator is, it still doesn’t assume responsibility for a ton of the failure points that managed services do. And that’s true even at modest scale (e.g. upgrades are just harder when you’re running your own DB) and in cost conscious environments (sure, the Elasticache bill is steep, but the salary and velocity cost of fixing memory-leak-caused kube memcached crashes is steeper).
