# n8n-kubernetes-hosting
Get up and running with n8n on the following platforms:
* [AWS](https://docs.n8n.io/hosting/server-setups/aws/)
* [Azure](https://docs.n8n.io/hosting/server-setups/azure/)
* [Google Cloud Platform](https://docs.n8n.io/hosting/server-setups/google-cloud/)
If you have questions after trying the tutorials, check out the [forums](https://community.n8n.io/).
## Prerequisites
Self-hosting n8n requires technical knowledge, including:
* Setting up and configuring servers and containers
* Managing application resources and scaling
* Securing servers and applications
* Configuring n8n
n8n recommends self-hosting for expert users. Mistakes can lead to data loss, security issues, and downtime. If you aren't experienced at managing servers, n8n recommends [n8n Cloud](https://n8n.io/cloud/).
## Contributions
For common changes, please open a PR to `main` branch and we will merge this
into cloud provider specific branches.
If you have a contribution specific to a cloud provider, please open your PR to
the relevant branch.
