Serverless functions map cleanly to API endpoints. Each request triggers a function that handles logic and returns a response. There’s no server to keep running between requests. Scaling happens automatically as traffic increases. This model reduces costs and simplifies deployment for modern API-driven applications.
API performance remains consistent even under heavy load. Costs scale with actual usage.
This approach supports the growth of mobile apps and SaaS platforms globally.
Serverless functions commonly power REST and GraphQL APIs.
