Senior LevelSystem Design & Architecture
Analyze architectural trade-offs: Monolith vs Microservices vs Serverless (FaaS).
❓ Interview Prompt: Compare Monolith vs Microservices vs Serverless (FaaS / AWS Lambda), operational overhead, deployment velocity, cold starts, and cost scalability.
Comparing system deployment paradigms:
•
Monolithic Architecture: Single unified code deployment. Pros: Easy debugging, zero network latency between modules. Cons: Scaling bottleneck, large blast radius.
•
Microservices: Independent deployment artifacts per domain. Pros: Independent team scaling, technology flexibility. Cons: High network complexity, distributed debugging overhead.
•
Serverless (FaaS): Event-driven execution (AWS Lambda). Pros: Zero server management, auto-scaling to zero cost. Cons: Cold-start latencies, vendor lock-in, short execution timeouts.

{
"paradigm": "Serverless (AWS Lambda + EventBridge)",
"idealUseCase": "Event-driven asynchronous tasks & unpredictable bursty APIs",
"tradeoff": "Low operational maintenance versus cold start latencies"
}💡Architectural comparison payload for Serverless FaaS paradigms.
🎯 Interview Key Takeaway
Choose Monoliths for early-stage products, Microservices for large multi-team domains, and Serverless for bursty event-driven workloads.
