## Deployment
|
||||||
|
|
||||||
|
When you're ready to deploy your NestJS application to production, there are some key steps you can take to ensure it runs as efficiently as possible. Check out the [deployment documentation](https://docs.nestjs.com/deployment) for more information.
|
||||||
|
|
||||||
|
If you are looking for a cloud-based platform to deploy your NestJS application, check out [Mau](https://mau.nestjs.com), our official platform for deploying NestJS applications on AWS. Mau makes deployment straightforward and fast, requiring just a few simple steps:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
$ npm install -g mau
|
||||||
|
$ mau deploy
|
||||||
|
```
|
||||||
|
|
||||||
|
With Mau, you can deploy your application in just a few clicks, allowing you to focus on building features rather than managing infrastructure.
|
||||||
|
|
||||||
|
