Does anyone have any recommendation for a reliable cloud host?
We require 1 or 2 very small virtual hosts to host some remote services to serve as backup to our main datacenter.
One of these services is a DNS server, so it is important that it is up all the time.
We have been using Rackspace Cloud Servers. We just realized that they have absolutely no redundancy or failover
after experiencing a outage that lasted more than 6 hours yesterday. I am appalled that they would offer something
called "cloud" without having any failover at all.
1. Full redundancy with instant failover to other hypervisor hosts upon hardware failure (I thought this was a given!)
2. Actual support (with a phone number I can call)
3. reasonable pricing (No, $800/month is not reasonable when I need a tiny 256MB RAM Server with <1GB/mo of data
Well, as everyone has been saying, unfortunately with "infrastructure"
clouds, you have to engineer your set up to their standards to have
For example, Amazon (as mentioned in the thread) give a 99.95% uptime
SLA *if* you set up failover yourself accros more than one
"Avaliability Zone" within a region. Details are at

Amazon, you can use support if you pay for it, it's not included as

services like that can be a little high for small setups, though they
do have a free edition that may be suitable.
You can get the same kind of 99.95% SLA from other providers if you
follow their deployment guidelines regarding their type of "zones".
Microsoft will do it for not too much

But let's not forget simply buying the software as a service is also
an option, where fail-over becomes Someone Else's Problem. For DNS,
EasyDNS (https://web.easydns.com/DNS_hosting.php) are rather good and
not too expensive, and you can get a 100% up-time guarantee if you
want. A review of them regarding availability is at
