Replit Deployments` is a revamped hosting infrastructure that offers faster deployment of applications in any language, with improved security, isolation, and control over when apps are released to users. The service has been rebuilt from the ground up after five years in beta, addressing issues such as frequent restarts, lack of isolation, and inadequate security measures. It provides isolated VM resources for better performance and security, allows users to link custom domains or use a custom subdomain under `.replit.app`, and offers more features like debugging with logs, pricing options that scale up to dedicated CPUs, and a mobile app for on-the-go deployment and monitoring. The service is built on Google Cloud Platform and aims to improve upon the legacy `Replit Hosting` product by adding more features and offering new deployment types, while also making it easier to grow from idea to full-fledged business.
