The document discusses serverless computing and Functions as a Service (FaaS). It promotes using FaaS to build microservices and serverless applications. It provides examples of using FaaS for tasks like processing payroll, running functions in response to events from services like chat bots, and accessing functions through an API gateway. Resources and tools are referenced for getting started with FaaS development.
