FaaS stands for Function as a Service, which is a type of cloud computing service that allows developers to write and deploy code without worrying about the underlying infrastructure. With FaaS, developers can write small, modular functions that are triggered by specific events, such as HTTP requests, database changes, or messages from a queue.
As more and more applications move to the cloud, FaaS will become more important. FaaS provides a cost-effective and scalable solution for deploying serverless applications, which is becoming increasingly popular. FaaS is also a great fit for IoT devices, which require a lightweight and scalable solution.
