How do you handle spikes in request volume? That is, one of the nice things about working in the cloud with dynamic sizing is that your costs should only be relative to your average load, not necessarily your peak load. Given the size of Swiftype, and the fact that you back tons of individual sites (instead of being your own site), there might be enough variance in the sites you back so that your peak and average load is pretty similar. For a single ecommerce site, though, they might get a huge peak over baseline if they do a big marketing push, for example. In that case, they might have to provision many more physical servers than they usually need to handle that peak. Just wanted to see if this issue came up in your planning.
