Design a cloud DevBox platform: a service that provides developers with disposable or persistent remote development machines accessible through a browser, SSH, or IDE plugins.
Clarify the product goals:
- Users can create, start, stop, pause, resume, and delete dev boxes from predefined templates.
- A dev box contains an operating system image, language/toolchain dependencies, repository checkout, user home directory, secrets, and allocated CPU, memory, storage, and optional GPU resources.
- The platform supports organizations and teams, quota enforcement, role-based access control, audit logs, and cost controls.
- The system should optimize for fast provisioning, high availability, scalability to many concurrent dev boxes, strong isolation, reliable persistence, and operational observability.
Quick Answer: This question evaluates understanding of system design and cloud infrastructure competencies, including virtualization/container orchestration, resource and lifecycle management, security, RBAC, multi-tenant architecture, and operational observability.
