Saving big on database-backed DevOps workflows by leveraging Spot instances

Most people know and agree - Postgres is an awesome datastore fit for a multitude of DevOps flows due to it's "lightness", for example - environment cloning for feature testing and similar. But how to make Postgres even better? By running it at a fraction of the cost! This talk sheds light on an avenue that only a few brave have dared to explore - running Postgres in the cloud using Spot VMs, while persisting state and being DevOps-friendly.

We start with a general overview of Spot VM characteristics, typical cost savings and common interruption statistics. Proceeding to deployment possibilities - K8s versus self-managed, and performance aspects, compared to typical managed databases like RDS Postgres.

To finish off, an example Open Source implementation of a "Spot-aware" Postgres toolkit (revolving around Ansible), designed to simplify and DevOps-ify dealing with Spot instance, is introduced and demoed.

Key takeaways:
- Explains the essence of Spot VMs and their behaviour
- Shows that Spot VMs can also be used for stateful workflows
