Seems like amazon has long been transitioning spot instances away from being a method of efficiently utilizing excess capacity, towards being a discounted service for less risk-averse businesses(businesses that can accept the risk of their service being terminated at any time).
Even if in practice AWS never sees large spikes in compute demand and corresponding large scale instance preemption, most businesses I've worked with won't accept the risk of having OLTP systems be taken down at any time.
No longer does spot seem to be a service where one can get a bargain for their compute intensive offline/batch workloads that are much more tolerant of preemption.
Given that the spot prices seem to be very flat, and preemption is rare, amazon presumably have a fair bit of underutilized capacity, does anyone know if amazon uses this capacity themselves, or offers more aggressive spot pricing to select clients?
