Which companies are using spot instances, and what are they using them for? Off the top of my head I can think of Netflix, but most companies haven't created their architecture to be that resilient.
We use it extensively at my old shop, Optaros, where I worked on quite a bit of that strategy. The VP of Operations spoke at AWS re:invent this year on how we use spot instances to massively cut down on costs: https://portal.reinvent.awsevents.com/connect/speakerDetail....
I'm wondering whether I should have asked the question "Why are people not using AWS spot instances?". It seems like the price savings alone should be enough for people to consider using them. Is the architecture too different where it makes deployment prohibitively difficult?
