# 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.
