Amazon is not cost effective unless the flexibility really matters -- Similarly, PrivateLog will initially be on Sakura because of both cost-performance on the actual processor performance but bandwidth as well. We'll see what happens. After I get more photos uploaded to there, I'm going to need to use a caching CDN to serve them -- I'm probably going to be looking at CloudFront at that point. CloudFlare's free bandwidth is nice, but I don't trust them as much as I trust CloudFront.
