## 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.
## Resources
Check out a few resources that may come in handy when working with NestJS:
- Visit the [NestJS Documentation](https://docs.nestjs.com) to learn more about the framework.
- For questions and support, please visit our [Discord channel](https://discord.gg/G7Qnnhy).
- To dive deeper and get more hands-on experience, check out our official video [courses](https://courses.nestjs.com/).
- Deploy your application to AWS with the help of [NestJS Mau](https://mau.nestjs.com) in just a few clicks.
- Visualize your application graph and interact with the NestJS application in real-time using [NestJS Devtools](https://devtools.nestjs.com).
- Need help with your project (part-time to full-time)? Check out our official [enterprise support](https://enterprise.nestjs.com).
- To stay in the loop and get updates, follow us on [X](https://x.com/nestframework) and [LinkedIn](https://linkedin.com/company/nestjs).
