Indeed, but that's completely leaving out the single most important thing: backups. With all of the major clouds, snapshots are easy to do both at a VM level and data level (e.g. RDS), and the cloud provider takes care that the backups are sufficiently spread to be disaster tolerant.

In contrast, when you co-locate you have to take care of backups completely on your own, and with many hosters you can't even influence in which of their DCs your servers will be.

If anything, OVHs SBG fire incident should have shown everyone how hard it is to build resilient systems.

Except against the disaster of the cloud deciding it's not worth to keep you as a customer, or the cloud having a distributed failure, or the cloud getting out of business...

You need your own backups even if you're running EC2. If for no other reason than the vendor disappears, and you want to recreate the system elsewhere.

It's the same problem if you run your own server or on someone else's systems. You need a backup and restore plan either way.
