Laravel Vapor is a platform developed for serverless applications, which is part of the Laravel ecosystem. This platform is designed to easily deploy and manage Laravel applications on cloud infrastructures such as AWS (Amazon Web Services). Laravel Vapor eliminates server management, allowing developers to focus more efficiently.

It offers the following features in particular:

1. Serverless Deployment: Your application runs on AWS Lambda, meaning there is no need for a physical server. Thus, the infrastructure management is completely handled by AWS.

2. Automatic Scaling: Resources are automatically scaled as your application's traffic increases.

3. Easy Management and Configuration: The settings and configurations of your Laravel application can be easily managed with the Laravel Vapor CLI.

4. CI/CD Support: Simplifies continuous integration and deployment processes.

5. Database and Storage Management: Provides integration with AWS's powerful database and storage services (e.g. DynamoDB, S3).

Vapor is especially useful for developers who want to deploy their Laravel projects in an AWS environment, as the entire infrastructure and management processes are much simplified.
