## AI overview

This Trino Summit 2022 session recap describes how Zillow runs Trino on inexpensive but ephemeral spot instances to reduce compute costs. Zillow uses multiple Trino clusters on Amazon EKS, with dedicated on-demand coordinator nodes and a tuned mix of spot and on-demand worker nodes to balance savings and reliability.

## Source excerpt

In this installment of the Trino Summit 2022 sessions posts, we jump into an exciting topic by folks from Zillow about running Trino on spot instances. Spot instances are cheap and ephemeral nodes that lead to reduced overall compute costs. Spot instances are cheaper as they are not guaranteed to remain available. In this session, Zillow engineers talk about how they use Trino on spots to take advantage of the cost savings while handling the transitory nature of spots.
