Gigabits per second, certainly. How many? We haven't exhaustively checked.

comment How can I deploy a scalable, reliable haproxy cluster on Amazon EC2?
Yeah, if an ELB spans multiple AZs and has some sort of failure where it cannot get to any of the backend nodes in an AZ (they're overloaded, down, returning 503s, whatever), end users see those errors - it doesn't re-route to the other AZ(s). I'm hoping that's planned, but it's bitten us once already.

comment How can I deploy a scalable, reliable haproxy cluster on Amazon EC2?
So I love approach #1, that's the direction I've been leaning, but there are still some interesting gotchas - not the least of which is that ELB doesn't handle an entire AZ failing very well (something we've had happen already). The easy, but yucky, 'solution' there is to have the haproxies behind ELB configured to cross AZs (maybe with a backup cluster in another AZ) so if at least one haproxy is up in each AZ, we should be fine. But that only mimimizes, not eliminates the problem. Any ideas around this problem?

comment EC2 instance backup
There are a lot of benefits to going with an EBS volume instead, such as faster boot times, but I can't tell you if it'll work for your use case or not. There is documentation out there on how to convert - but make sure you've backed up your ephemeral storage first or you may lose it if you don't make the transition right.

We use puppet in our datacenters, but haven't tried on EC2 yet. Is puppet EC2-aware somehow, such that it can find nodes using ec2-describe-instances or something, and automagically configure / reconfigure based on that output? And how would you handle the puppetmaster going away suddenly?
