EC2 comes with a free Chaos Monkey service. It's called EC2. I know, they're trying to make it reliable and they've got a bunch of very hard problems to solve.

EC2 comes with a free Chaos Monkey service. It's called EC2. I know, they're trying to make it reliable and they've got a bunch of very hard problems to solve. That doesn't change the fact that sometimes some of my servers just permanently stop responding to pings until you stop-start them, or get crazy-slow I/O, or get hit by these once-in-a-while-and-always-at-night outages. It's great when you suddenly need a hundred more servers, though.
