Spot Traces

This repository contains spot availability and preemption traces collected from the cloud providers and the scripts to collect and process the traces.

The data was used in paper Can't Be Late: Optimizing Spot Instance Savings under Deadlines (NSDI 24). The policy in the paper is prototyped on SkyPilot.

Data Description

We collected the spot instance availability and preemption traces by directly pinging the cloud providers. The traces contain the following information:

{
  "metadata": {
    // The interval seconds between two consecutive data points
    "gap_seconds": 300,
  },
  // A trace of spot instance availability or preemption, where each data point
  // is the number of available instances at a specific tick.
  "data": []
}
