Anyway, a Fortune 500 company usually controls the complete hardware, have staff in the DC (or their own DC ...) - that's kind of different of trusting a 3rd party with it - and way more costly. Also, just because they use it in production it doesn't mean they solely rely on it.
Additionally you need to keep off-site backups for yourself anyway no matter how "secure" you think something is (imagine a host going broke, fire/fatal accident in a DC, roque employee calling an rm -rf *, whatever) - like big companies "cloning" their DC completely a few hundred miles away, use tape storage systems, etc... |
Off-site back ups and having a redundant infrastructure have nothing to do with each other. Having 1 dedicated server = many single points of failure. Being hosting on a virtualization playform (if created correctly) = 0 points of failure. Great, you have offsite back ups. How long will it take you to restore, compared to rebooting a server if you have hardware failure.
Lets say you do have offsite back ups. They are 200GB. Your server breaks. The steps you need to take are simple.
Choice 1. Dedicated Server.
1. Get a new server.
a. Your host must have exact server in stock,
2. The OS needs to get installed.
3. You have to grab your backups from other location.
4. You have to extract backups and re-configure server from backups.
Choice 2. Cloud/Virtualization Server
1. Do nothing.
Do you know how much easier it is to backup and restore a virtual machine compared to a regular hosted OS?
Most companies do whats called. Disk to Disk to tape Backup, if they are still using tapes. The only people still using tapes are the ones that either have it as a regulatory compliance or because they have it in some company guidelines. Most up to date companies are doing Disk to Disk to Cloud.
If you know the reasons there really should be a choice. If you think most companies don't use virtualization in production. You are just misinformed or un-educated on the topic. Get a VM from Rackspace. They wont go out of business. If you are worried that your host might go out of business. You are probably with the wrong host in the 1st place.
