Feature Overview
Add support for short lived instances on clouds that provide it
Goals
- Support spot instances on AWS
- Support preemptible VMs on Azure
- Support preemptible VMs on GCP
Requirements
| Requirement | Notes | isMvp? |
|---|---|---|
| Indicate a workload should run as a spot instance | TBD | Yes |
| Identify which workloads are selected to run as spot instances | Yes | |
Out of Scope
Job scheduling based on price of spot instances i.e. providing a watermark of when you would use spot instances
Background, and strategic fit
Short lived instances can help customers drive down IaaS costs.
Assumptions
Customer Considerations
Customers applications must be architected without NodeSelectors or any other ties to the Node, because they will be coming and going often.
Documentation Considerations
- Target audience: cluster admins
- Updated content: update autoscaling docs to mention that you can use this types of instances
