Upsun Autoscaling API

Upsun provides native support for autoscaling, allowing your applications to automatically adjust based on resource usage.This ensures that your apps remain responsive under load while helping you optimize costs.You can configure thresholds for metrics such as CPU, RAM, and request latency. Resources will automatically scale to meet demand.Each container profile assigned to an application or service provides a specific combination of CPU and RAM, which you can select via the Upsun UI or CLI.These endpoints manage autoscaling configurations that are tied to aspecific environment, and optionally to its child environments.You can define scaling rules based on metrics like CPU, memory, orrequest latency, and these rules will be applied at both build timeand runtime. For more information on configuring autoscaling for yourenvironments, see the [Autoscaling](https://docs.upsun.com/manage-resources/autoscaling.html) sectionof the documentation.

Upsun Autoscaling API is one of 50 APIs that Upsun publishes on the APIs.io network, described by a machine-readable OpenAPI specification.

Where this information came from

This is an independent, third-party profile of Upsun Autoscaling API, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.

The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.

Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
