Serverless Functions for Event-Driven APIs

Serverless functions (also known as Functions as a Service or FaaS) are code snippets that run in response to events, without you having to manage any servers.

The cloud provider (like AWS, Azure, or Google Cloud) handles all the underlying infrastructure, from provisioning servers to scaling and patching them.

• You just write your code.
• The cloud runs it when needed.
• You only pay for the compute time used.

When building APIs, serverless functions offer incredible advantages, especially for event-driven architectures.

Instead of managing web servers, you can deploy individual functions that respond to HTTP requests. This simplifies operations significantly.

• Auto-scaling: Handles traffic spikes automatically.
• Cost-effective: Pay only for actual usage.
• Faster Development: Focus on business logic, not infrastructure.
