Serverless Architecture Deep Dive

# Serverless Architecture Deep Dive
Serverless doesn't mean no servers—it means you don't manage them. Here's when it makes sense.
## Benefits
**Automatic Scaling**
From zero to millions of requests without configuration.
**Pay Per Use**
Only pay for actual compute time, not idle resources.
**No Infrastructure Management**
Focus on code, not servers.
## Limitations
- Cold starts
- Execution time limits
- Vendor lock-in
- Debugging complexity
## Best Use Cases
- Event-driven workloads
- Irregular traffic patterns
- Rapid prototyping
- API backends with unpredictable load
## Common Patterns
- API Gateway + Lambda
- S3 event processing
- Scheduled jobs
- Async processing queues
Serverless shines for the right workloads but isn't a silver bullet.
