alt Hacker News> Surely you must've noticed that pretty much all of their bare metal offerings ("dedicated" and the stuff on "auction") have multiple disks, allowing for various RAID configurations?
I don't know where to start with this comment. Do I really need to spell out the difference between cloud and bare metal ?
A few examples...
- Live migration ? Cloud only.
- Snapshots ? Cloud only.
- Want to increase disk space ? Tick box in cloud vs. replace disks (or move to different machine) and re-install/restore in bare metal....
- Want to increase RAM ? Tick box in cloud vs. shutdown, pull out of rack, install new chips (or move to different machine and re-install/restore)....
- Want to upgrade to a beefier processor ? Tick box in cloud vs move to a completely different machine and re-install/restoreReplies

Well you did say your data is lost when a disk fails, which is not true. Parent pointed out that for you.
Yeah you pay for and get additional stuff with cloud. Nobody disputed that.

You can get snapshots and live migrations working on-prem. The cloud isn't magic, it's just servers with hypervisors and software running on top of them. You can run that same software.
Also, with something like Hetzner you would not be going in and physically doing anything. You also just tick a box for a RAM upgrade, and then migrate over or do active/passive switch.
The cloud does have advantages, mostly in how "easy" it is to do some specific workflows, but per-compute it's at least 10x the cost. Some will argue it's less than that, but they forget to factor in just how slow virtual disks and CPU are. Cloud only makes sense for very small businesses, in which the operational cost of colocation or on-prem hosting is too expensive.
