Single-site-2-absurdly-intense-days failover, yes. With weeks of cleanup afterwards.
What every company seems to want: multisite, multimaster immediate failover, no.
Also kubernetes buys you scaling. Compute. Disk. Database (with help). Etc.
Now I rail against companies for wanting that, and I think you're right. Your webshop does not need that. It has so many moving parts the redundancy will cause more outages than it solves. But you can do this, and so people will pay for it.
It is a technical accomplishment.
And with sufficiently good sysadmins, it can work well, and scale.
