This adds support for launching Amazon EC2 Spot instances (https://aws.amazon.com/ec2/spot/), which comes with huge cost saving opportunities. Amazon EC2 Spot instances are spare Amazon EC2 capacity, you can get with an discount of up to 90% compared to on-demand pricing. In contrast to on-demand instances, Spot instances can be relaimed with a 2 minute notification in advance (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-interruptions.html). When :attr:`providers.[aws].pools.labels.use-spot` is set to True, the AWS driver will launch Spot instances. If an instance get interrupted, it will be terminated and no replacement instance will be launched. Change-Id: I9868d014991d78e7b2421439403ae1371b33524c |
