As the Reserved Instance leases were up for both the EC2 and RDS pieces of the site, I wanted to do some testing in other environments. After a bit of looking around, I decided to give Linode a shot, and The Beer Cellar has now been migrated to one of their servers.
On the user end, if I did everything correctly, no one should notice a thing. In fact, loading speeds may actually be measurably quicker for some users, as the database—the primary bottleneck for those with large cellars—is now served from an SSD. There is now also considerable CPU and memory headroom, which won't hurt.
Enjoy! And if you notice anything awry, please don't hesitate to let me know.
