Cloud Computing — Serverless Computing

Serverless computing allows developers to focus on writing code without worrying about managing servers or infrastructure. The cloud provider automatically allocates resources and runs the code when triggered by an event, such as a user clicking a button or uploading a file. Users pay only for the time their code runs, making it cost-effective and scalable. This is ideal for applications with unpredictable workloads or microservices architectures. Popular serverless services include AWS Lambda, Google Cloud Functions, and Azure Functions. Serverless also encourages faster development cycles by reducing operational complexity.

Example: A serverless function automatically resizes images whenever a user uploads them to a cloud storage bucket.
