# Serverless Workers - Java SDK > For the complete documentation index, see [llms.txt](https://docs.temporal.io/llms.txt). > Any documentation page is available as raw Markdown by appending `.md` to its URL. > Write Temporal Workers that run on serverless compute using the Java SDK. > **Public Preview** Serverless Workers run on ephemeral, on-demand compute rather than long-lived processes. Temporal invokes the Worker when Tasks arrive, and the Worker shuts down when the work is done. For a general overview of how Serverless Workers work, see [Serverless Workers](/serverless-workers). For the end-to-end deployment guide, see [Deploy a Serverless Worker](/production-deployment/worker-deployments/serverless-workers). ## Supported providers - [**AWS Lambda**](/develop/java/workers/serverless-workers/aws-lambda) - Use the `temporal-aws-lambda` contrib module to run a Worker as a Lambda function. Covers setup, configuration, Lambda-tuned defaults, observability, and the invocation lifecycle.
