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/restoreYeah you pay for and get additional stuff with cloud. Nobody disputed that.
Well, technically its still a possibility.
I am old enough to have seen issues with RAID1 setups not being able to restore redundancy, as well as RAID controller failures and software RAID failures.
Also, frankly you are being somewhat pedantic. My broader point was regarding cloud. I gave HD Failure as one example, randomly selected by my brain ... I could have equally randomly chosen any of the other items ... but this time, my brain chose HD.
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.
are you a capable engineer or do you believe in magic?
the savings of a cheap engineer disappear on the cloud bill. get a badass well paid engineer who can do both and doesn't talk his way out of this financial madness
Well, fine, but its abundantly clear that this blog post was not written by a "badass well paid engineer".
The person who wrote that blog post was clearly unaware of the trade-offs of the decisions he was making.
