We recently moved to attribute based instance selection for our web traffic. It turns out that there's a ton of capacity in random instance classes at various times. Sometimes it's c6a.metal with 192 vCPU. Sometimes it's i3.metal with 64 vCPU. We've been able to get the capacity we need much more readily with this configuration. (everything is spot btw)
