1. What is Serverless Computing?
- Definition: Serverless doesn’t mean “no servers” — it means developers don’t manage them.
- FaaS explained: Code runs in response to events without worrying about server infrastructure.
- Examples: AWS Lambda, Google Cloud Functions, Azure Functions.
-
Benefits:
- Automatic scaling
- Pay-as-you-go model
- Simplified deployment and maintenance
📝 LSI keywords: serverless architecture, FaaS platforms, cloud-native development.
2. What is Edge Computing?
- Definition: Computing closer to the user/device to reduce latency.
- Edge vs Cloud: Explain how pushing workloads to the “edge” speeds up response times.
- Real-world use cases: IoT devices, CDNs, AI inference at the edge, personalized content delivery.
- Examples: Cloudflare Workers, Vercel Edge Functions, AWS Lambda@Edge.
📝 LSI keywords: edge network, latency reduction, CDN functions, distributed computing.
3. Serverless vs Edge: What’s the Difference?
| Feature | Serverless | Edge Computing |
|---|---|---|
| Location | Centralized cloud regions | Near user (edge nodes) |
| Latency | Good | Excellent |
| Use cases | APIs, batch jobs, event-driven | Real-time apps, personalization, IoT |
| Examples | AWS Lambda, Azure Functions | Cloudflare Workers, Vercel Edge |
- Note: Many modern architectures combine both.
4. Advantages of Going Serverless or Edge
- Reduced DevOps overhead
- Faster response times and better UX
- Easier scalability during traffic spikes
- Cost efficiency
- Better focus on product logic, not infrastructure
