[LRUG] Hosting on EC2?

[Tom Taylor]

Has anyone had any experience of Rails hosting on Amazon EC2?

We're building a thingy for Big Corp. EC2 is (bizarrely) one of their  
approved hosting options. Considering all the other hosting options  
are .NET 'specialists' and look very scared when we mention Rails, EC2  
might be least painful option.

I understand that you need to have two instances with Master-Master  
database replication because you never get your instances back as you  
left 'em when/if they go down. What else do I need to be aware of?

Cheers,

Tom
