The cloud significantly lowers capital expenditure to get into an Internet-enabled business, which cultivates the very startup ecology that Y Combinator exists to leverage and support. Those teenagers who started the Facebook Pokemon game would have never had the resources to build a scalable solution with hardware that they own. (That is, unless Y Combinator paid a lot more money as part of participating. They might…

If you start with the cloud, you best formulate an "exit plan". Reddit for example doesn't seem to have one and seems quite stuck.

We're not that stuck. We can be out of Amazon in a month if necessary. We very specifically don't use any of their "lock-in" services to make easier on our open source users, which has the side effect of not locking us in either.

Did you guys find a better cloud service, or did you roll your own in a datacenter somewhere?

We went with a managed hosting provider who built us a private cluster. Basically a private cloud. But that way we could get a dedicated SAN and move our DB servers out to dedicated boxes with whatever disk configuration we desired.

Which provider? Can you email me? jedberg@reddit.com.

That is entirely wrong. With AWS, we've built a multi-AZ load balanced infrastructure for very little time and money. Getting an equivalent setup out of our own hardware would have been orders of magnitude more expensive and time consuming.

Can you please explain how you built a multi-AZ load balanced infrastructure, given that Amazon's ELB only load balances within a given AZ. I assume you used some external service. Would you mind providing the details. Thanks.

ELB load balances very easily across availability zones. In fact, that pretty much seems to be the setup they expect you to use. It doesn't allow you to balance across regions, though, which may be what you mean.

Word in the industry is that AWS is insanely profitable, so they've got not problem finding the money to hire the help. My gripe with EBS is that hiccups in EBS cause my Linux instances to "lock up", consume 100% CPU and become unresponsive. AMZN is providing their own Linux distribution and drivers for the EBS devices so they can also attack this problem by patching the Linux kernel.

If you switch to their distribution, do you get any benefit now?

Compatibility with the platform is excellent and it's comfortable for anyone who's familiar with Red Hat or Fedora.

I'd compile my own web server stack, but it's as good a foundation to build on as any Linux distribution.

Ya, thanks for the response. I went and double checked what ELB does. I was looking for a way to load balance across regions. I know some services that can do it, but are quite expensive.

I use the Rackspace cloud for a few Windows servers. The experience has been mostly positive, but they disappear for a few minutes each week, which is kind of troubling.

Disappear as in they crash and reboot, or disappear as in they're unpingable?

Gah, sorry for the late response, I just saw this. They just go unpingable for a few minutes. They seem fine when they return from purgatory.

It's always been at random times overnight, so far it hasn't happened when I know there's been load on the servers.

I firmly believe "the cloud" is a fad, unless for some reason you own and operate all the hardware yourself (ie. Google). Like other technical fads, everyone will probably come back to servers they can reach out and touch when needed, sooner or later.
