I'd like to thank you and everyone else for the informative replies.
My real goal is to setup a redundant instance of our current systems.
I would like to setup mysql master-master relationships and ryncs of http data
between the office systems and the cloud.
The data I'm dealing with is rather sensative as well. What security
the office and the cloud

Subject: Re: [lug] cloud recommendation
Amazon and Rackspace are probably the biggest players in this market right now,
but Microsoft and others are getting into it as well. My recommendation would
be for Amazon's EC2 cloud. There are CentOS images (AMI's) available - if you
want to get up and running quickly I'd search for the Rightscale ones. You can
also get a fully licensed Red Hat image for EC2. Some images are
"instance-store" backed, meaning that data is not persistent. If you stop the
instance (virtual server) and start it again, all changes will be lost. Others,
however, are EBS-backed. EBS stands for Elastic Block Storage, and it's
Amazon's way of providing semi-permanent storage for your instances. Basically,
you create an EBS volume and it then behaves rather like a traditional hard
drive. You can attach it to a running instance, format it with a filesystem,
etc. The data is persistent until you delete the EBS volume. You can also take
a snapshot of an EBS volume at any time. Instances that are EBS-backed *are*
persistent, and you can stop and restart them without losing changes. The
downside is that you pay for EBS storage in addition to the per-minute running
time of your instance. However, personally, I think that the small extra cost
is well worth it.
