+# Serverless Computing (无服务器计算)
+
+## Definition
+**Serverless Computing** is a cloud execution model where the cloud provider dynamically manages the allocation and provisioning of servers. Developers can build and deploy applications without worrying about infrastructure management.
+
+## Key Characteristics
+- **No server management**: Cloud provider handles infrastructure
+- **Automatic scaling**: Resources scale based on demand
+- **Pay-per-use**: Pay only for execution time
+- **Event-driven**: Functions respond to events/triggers
+
+## Key Platforms
+
+| Provider | Service |
+|----------|---------|
+| AWS | Lambda |
+| Azure | Azure Functions |
+| GCP | Cloud Functions |
+
+## Benefits
+
+### 1. Cost Efficiency
+- Eliminates unnecessary resource consumption
+- No idle capacity costs
+- Pay only for actual execution time
+
+### 2. Scalability
+- Automatic scaling from zero to thousands of instances
+- Handles traffic spikes without provisioning
+- Global distribution ready
+
+### 3. Developer Productivity
+- Focus on business logic, not infrastructure
+- Faster deployment cycles
+- Reduced operational overhead
+
+## Use Cases
+
+### Event-Driven Automation
+- Real-time file processing
+- Automated backups
+- Scheduled tasks and cron jobs
+
+### API Backends
+- Microservices architecture
+- Real-time data processing
+- IoT data ingestion
+
+### AI/ML Inference
+- On-demand model inference
+- Image and video processing
+- Natural language processing
+
+## Relationship to Green Computing
+- Serverless computing contributes to [[Green Computing]] by:
+  - Eliminating idle resource consumption
+  - Optimizing energy efficiency through shared infrastructure
+  - Reducing data center carbon footprint
