# Serverless Workers - Java SDK

> Write Temporal Workers that run on serverless compute using the Java SDK.

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.
