# Spot Autoscaling

**Status: Coming soon**

Spot Autoscaling will automate the use of cloud provider spot/preemptible instances for fault-tolerant workloads, capturing the deepest available discounts for interruptible compute.

### What it will do

Spot instances (AWS), preemptible VMs (GCP), and spot VMs (Azure) offer discounts of 60% to 90% compared to on-demand pricing. The tradeoff is that the cloud provider can reclaim these instances at any time when capacity is needed elsewhere.

Pump's Spot Autoscaling will manage this tradeoff by:

1. **Identifying eligible workloads.** Analyzing your running workloads to determine which can tolerate interruption (batch processing, CI/CD, stateless web tiers, data pipelines).
2. **Managing spot lifecycle.** Handling instance bidding, interruption notices, and automatic replacement.
3. **Diversifying across pools.** Spreading spot usage across multiple instance types and availability zones to reduce interruption risk.

### How it relates to other Pump Save mechanisms

| Mechanism                      | Layer                                                                     |
| ------------------------------ | ------------------------------------------------------------------------- |
| Commitment Planner             | Pricing: discounts on committed, predictable usage                        |
| Infrastructure Recommendations | Sizing: right-size or eliminate underused resources                       |
| Kubernetes Auto-Scaling        | Pod sizing: reduce compute per pod                                        |
| Spot Autoscaling               | Instance type: shift eligible workloads to the cheapest available compute |

Spot savings apply on top of right-sizing. A workload that has been right-sized and moved to spot instances captures savings at both layers.

### When it will be available

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.pump.co/pump-save/spot-autoscaling.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
