+
+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 @nestjs/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.
