# Caching via remote runners Caching via remote runners (such as Earthly Satellites) works by simply reusing the same runner for multiple builds. The runner retains the cache between executions, and thus is able to perform significantly better than any caching mechanism that relies on upload and download. There is nothing special that needs to be configured for this to work. All of the features of caching in Earthly work as expected, including layer caching and cache mounts. Remote runners can be either self-hosted, or managed by Earthly - see [Earthly Satellites](/earthly-0.7/earthly-cloud/satellites.md). To learn more, see the [remote runners page](/earthly-0.7/docs/remote-runners.md). The [managing cache page](/earthly-0.7/docs/caching/managing-cache.md) contains information about how to reset the cache remotely, if needed. --- # Agent Instructions: 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: ``` GET https://docs.earthly.dev/earthly-0.7/docs/caching/caching-via-remote-runners.md?ask= ``` The question should be specific, self-contained, and written in natural language. 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.
