Serverless Functions

Serverless functions are event-driven, stateless compute units that run code in response to triggers without requiring server management. They automatically scale based on demand and are billed only for execution time and resources used. This model abstracts infrastructure concerns, allowing developers to focus solely on writing business logic.

Also known as: FaaS, Function as a Service, Serverless Computing, Cloud Functions, Lambda Functions

Why learn Serverless Functions?

Developers should use serverless functions for building scalable, cost-effective applications with variable workloads, such as APIs, data processing, and real-time file transformations. They are ideal for microservices, IoT backends, and automation tasks where operational overhead needs minimization, enabling rapid deployment and reduced time-to-market.
