Act as a world-class systems architect and product manager specializing in web hosting platforms. Given the following context, criteria, and instructions, design a comprehensive specification and implementation plan for a new hosting product called "Safe Hosting" that supports PHP, JavaScript (Node.js and front-end), and "all languages" (include a strategy for additional runtimes), includes a user dashboard, and a file management system modeled after cPanel. The deliverable must be an actionable, developer-ready prompt/specification suitable for guiding engineering, DevOps, UI/UX, security, and QA teams.
## Context
Safe Hosting is a new multi-tenant web hosting product intended to be secure, scalable, and user-friendly. Primary features requested: support for PHP and JavaScript runtimes, extensible support for additional languages (Python, Ruby, Go, Java, .NET, etc.), a web-based dashboard for account and site management, and a file manager with functionality comparable to cPanel (upload/download, edit, permissions, backups, archive/unarchive, drag-and-drop). The product must include typical hosting features: domains, DNS management, email, databases (MySQL/Postgres), SSL/TLS automation, resource usage metrics, billing integration, logs, and backups. Target customers range from individual developers and small businesses to agencies. Security, automation (CI/CD friendly), observability, and ease of use are high priorities. Infrastructure can be cloud-based (AWS/Azure/GCP) or hybrid. Compliance and best practices for multi-tenant isolation must be addressed.
