Hey guys, I've been thinking about the idea of running a elasticsearch cluster in AWS/EC2 mixing "normal" (on-demand or reserved) instances with spot instances.
The motivation is simple: spot instances run just as fast as a normal instance but with a much lower price/hour. With the "only" caveat being that the instance can die at any moment (if the floating price goes higher than your bid). The idea is to have a 50/50 or 30/70 split between normal and spot instances. For example, 4 normal instances and 8 spot instances. My questions/doubts are: - Has any one tried this kind of setup? - One "safety" issue is that master/primary shards can be allocated in spot instances which are prone to die. Anyway around this? Maybe allocate all primaries in the "normal instances"? - The number of spot instances can't be much higher than the number of normal instances. That would mean that, maybe, a shard woulnd't have a replica in at least one of the normal instances, which could be risky. Anyway around this? Any thoughts?
