Scylla and Spotinst together provide a strong combination of extreme performance and cost reduction. In this talk, we will present how a Scylla cluster can be used on AWS’s EC2 Spot without losing consistency with the help of Spotinst prediction technology and advanced stateful features. We will show a live demo on how to run Scylla on the Spotinst platform.

Prediction is the Key!
8
Spotinst uses predictive analytics, algorithms and historical data to identify
and predict Spot Instances that are about to be “interrupted”.
Prior to termination, Elastigroup automatically and seamlessly transitions applications to the least expensive
“available” instances with absolutely no downtime regardless of application type or demand.
