Rackspace spot
Has anyone used it? Seems to be similar to the spot instances by big cloud, except the prices look really good. e.g.
There do seem to be some gotchas - the $10 load balancer appears compulsory, has to be k8s and storage and egress is charged separately. So doesn't directly compete against VPS market as such.
NB these are preemptible nodes...i.e. you get kicked out if market price rises over your bid
