FaaS

A cloud computing model that allows developers to run individual functions or small pieces of code in response to specific events—without managing servers or infrastructure. Often referred to as serverless computing, FaaS automatically provisions, scales, and executes code only when triggered, charging users solely for the compute time consumed.

With FaaS, developers can focus entirely on writing application logic while the cloud provider handles all operational concerns such as server provisioning, runtime management, and scaling. This architecture is ideal for event-driven workloads such as API calls, data processing, IoT event handling, and scheduled tasks.

Common FaaS platforms include AWS Lambda, Google Cloud Functions, Microsoft Azure Functions, and Cloudflare Workers. These services integrate easily with other cloud components, allowing developers to build highly modular, efficient, and cost-effective systems.

FaaS enables faster development, automatic scaling, and near-instant deployment, making it a key building block of modern cloud-native and microservices architectures.
