It's easier for apps since you can build in failover support based on multiple servers pretty easily (I just implemented this in our 'live' installers recently on Windows). It's a bit harder at the website level for an average user, though. I know far too many people that have a single point of failure website on a super-cheap VPS that's just down whenever the VPS is down. Most of them would have no idea how to implement a load balancer and failover support. Though I could probably get them into something like CloudFare or similar.
