Function as a Service (FaaS)

FaaS is a category of cloud computing that provides a platform for customers to develop, run, and manage application functions without infrastructure complexity.

What is Function as a Service?

Function as a Service (FaaS) is a serverless approach to executing modular pieces of code on the edge. FaaS lets developers write and update code on the fly, which can then be triggered by specific events or requests.

How does FaaS work?

With FaaS, developers write individual functions that perform a single task. These functions are deployed to the cloud and execute only when triggered. The cloud provider manages all underlying infrastructure.

FaaS vs. other cloud models

Unlike Infrastructure as a Service (IaaS) or Platform as a Service (PaaS), FaaS abstracts away all server management. Developers interact only with individual functions, not with servers, containers, or runtime environments.
