Requirements

Event-driven Execution: The framework should execute code (functions) in response to various events (e.g., HTTP requests, message queue events, file uploads).
Multiple Language Support: Supports various programming languages (Node.js, Python, Java, Go, etc.) for writing functions.
API Management: Provide an API Gateway to expose functions as HTTP endpoints.
Trigger Management: Easy configuration for setting up triggers linked to specific functions.
Automatic Scaling: Function instances should automatically scale up with demand and scale down when idle.

Performance: Low latency in function execution and quick response times, even on cold starts.
Scalability: Must handle varying loads, from a few requests to thousands simultaneously without degradation.
Reliability: Should ensure high availability with no single points of failure.
Security: Functions should run in isolated environments with access control.
Cost-efficiency: Users should only pay for resources actually consumed (execution time, memory usage).
