Design a Cloud Infrastructure for a Tech Company

Functional Requirements:

• Users can provision and manage cloud resources (e.g., virtual machines, storage, databases) via APIs or a web interface.
• Support for creating, updating, and deleting resources.
• Users can monitor the status and usage metrics of their resources.
• The system should support user authentication and authorization for resource access.
• Resources can be tagged and organized by project or team.

Non-Functional Requirements:

• Scalability: The infrastructure should support growth in both the number of users and resources, scaling horizontally as needed.
• Availability: The system should be highly available, targeting 99.9% uptime.
• Performance: API requests for resource management should complete within a few seconds under normal load.
• Security: All data in transit and at rest must be encrypted; access should be controlled by roles and permissions.
• Reliability: The system should be resilient to failures, with mechanisms for backup and disaster recovery.
• Cost Efficiency: The architecture should optimize for cost, using auto-scaling and resource pooling where possible.
