Did you mean EBS? I thought it was generally hard to get the same kind of performance from block storage that local ephemeral storage provides but perhaps Amazon has found a way. Life would certainly be much simpler with a single ephemeral backend. Storage pools

Yes, I meant EBS not ECS. Too many similar acronyms... The thing about the Amazon folk is that they collect a lot of metrics, and pretty much do everything on a fairly empirical basis. This is a huge advantage. Starting thinking about what I could with good metrics and building on the performance

As far as I can tell when you specify: dhcp_agents_per_network = X 1 The server binds the network to all the agents (up to X), which means that you have multiple instances of dnsmasq serving dhcp requests at the same time. If one agent dies, there is no fail-over needed per se, as the other
