1. Deployment Model: Architect is a self-managed solution where you deploy and manage your Laravel application on your chosen cloud infrastructure, while Laravel Vapor is a serverless deployment platform specifically designed for Laravel applications, handling the server provisioning, scaling, and monitoring automatically.
2. Cost Structure: Architect requires you to manage and pay for the infrastructure resources directly, such as virtual machines and databases, based on usage or subscription plans, whereas Laravel Vapor operates on a pay-per-use model, where you only pay for the actual serverless resources consumed by your application.
3. Service Integration: Architect allows for the integration of various third-party services and tools by manually configuring them within your infrastructure setup, while Laravel Vapor offers seamless integration with AWS services like DynamoDB, S3, and more through its platform for simplified development and management.
4. Scalability: Architect provides flexibility in scaling your infrastructure vertically or horizontally based on your needs but requires manual configuration, whereas Laravel Vapor automatically scales your application horizontally by spinning up new instances in response to increased traffic, ensuring high availability and performance without user intervention.
5. Maintenance and Updates: Architect necessitates managing server maintenance tasks and updates for your infrastructure components, including OS patches and security fixes, whereas Laravel Vapor handles these aspects behind the scenes, ensuring that your application and underlying infrastructure remain up-to-date and secure without extra effort.
6. Deployment Speed: Architect deployments might require more manual configuration and time to go live due to infrastructure setup, configuration, and testing steps, while Laravel Vapor streamlines the deployment process, enabling quick and efficient launches of Laravel applications with minimal setup overhead.

In Summary, Architect provides more control over infrastructure management and deployment customization, while Laravel Vapor offers a serverless solution with automated scaling, cost efficiency, and simplified integration with AWS services.
