The DCAE platform is responsible for running and managing DCAE service components reliably. Currently, the DCAE platform supports two types of components, CDAP applications and Docker containers. For each, there are requirements that must be met for the component to integrate into the DCAE platform (see [CDAP](component-type-cdap.md) and [Docker](component-type-docker.md)). -### Components requires one or more data formats. +### A Component requires one or more data formats. -Components are software applications that do some function.
