AWS Lambda - Serverless Computing (11 min)

What is AWS Lambda?

AWS Lambda is a serverless compute service that lets you run code in response to events without provisioning or managing servers. You simply upload your code, and Lambda automatically handles the compute resources needed to run and scale it.

How Serverless Computing Works

With Lambda, you pay only for the compute time you consume — there's no charge when your code isn't running. Functions can be triggered by events such as file uploads, API calls, or database changes, making it ideal for event-driven architectures.

Common Lambda Use Cases

Lambda is commonly used for building APIs, real-time file processing, data transformation, automation tasks, and backend services for mobile and web applications without the overhead of managing servers.
