title: str = "Serverless Architecture and Event-Driven Design"

content: str = """
Serverless architecture allows developers to build and run applications 
without managing the underlying infrastructure. It is characterized by 
automatic scaling, high availability, and a pay-for-use billing model.

**Core Characteristics:**
1. **No Infrastructure Management:** The cloud provider handles server 
   provisioning, patching, and maintenance.
2. **Elastic Scalability:** The system scales automatically in response to 
   incoming request volume, from zero to thousands of concurrent executions.
3. **Event-Driven:** Serverless functions (FaaS) are typically triggered by 
   events such as HTTP requests, file uploads, or database changes.

**Event-Driven Design Patterns:**
*   **Pub/Sub:** Decoupling services using a message broker (e.g., AWS SNS, 
    Azure Service Bus). Producers publish events to topics, and consumers 
    subscribe to them.
*   **Event Sourcing:** Storing the state of a system as a sequence of 
    immutable events rather than just the current state.
*   **CQRS (Command Query Responsibility Segregation):** Separating the 
    read and write operations of a data store to optimize performance and 
    scalability.

While serverless reduces operational overhead, architects must manage 
challenges such as "cold starts" (latency during the first execution), 
vendor lock-in, and the complexity of monitoring distributed, ephemeral 
functions.
