You can build serverless functions by creating event-driven handlers that respond to triggers like S3 bucket events. This approach abstracts server management, allowing you to run code automatically in response to specific events without provisioning infrastructure.

Yes, serverless functions are ideal for building scalable API backends. Each API request can trigger a function to process data and return a response, automatically scaling with demand while eliminating the need to manage backend servers.

Deploying serverless functions requires an understanding of event triggers, stateless design principles, and AWS IAM for configuring permissions. You define a handler function to process events from connected services.

Serverless computing is best used for microservices, background processing, and scalable API backends when you want to automatically scale with demand and avoid the operational overhead of managing server infrastructure.

Stateless design requires functions to not retain data between executions, meaning you must manage state externally. This approach is necessary for automatic scaling but requires careful handling of persistent data outside the function.
