| --- |
| |
| Pulsar provides two modes to deploy a function: |
| * [cluster mode (for production)](functions-deploy-cluster.md) - you can submit a function to a Pulsar cluster and the cluster will take charge of running the function. |
| * [localrun mode](functions-deploy-localrun.md) - you can determine where a function runs, for example, on your local machine. |
| |
| ## Prerequisites |
| |
| Before deploying a function, you need to have a Pulsar cluster running first. You have the following options: |
| * Run a [standalone cluster](getting-started-standalone.md) locally on your own machine. |
| * Run a Pulsar cluster on [Kubernetes](deploy-kubernetes.md), [Amazon Web Services](deploy-aws.md), [bare metal](deploy-bare-metal.md), and so on. |

| :::note |
| |
| If you want to deploy user-defined functions in Python, you need to install the [python client](client-libraries-python.md) on all the machines running [function workers](functions-concepts.md#function-worker). |
