In Mendix development, what is a 'brew'?

In Mendix development, a 'brew' refers to a deployment unit or package of application code. It is essentially a collection of components, configurations, and resources that are packaged together to facilitate easy deployment and management of an application within the Mendix environment. This concept streamlines the process of application deployment, allowing developers to encapsulate their work into a single unit that can be versioned and deployed efficiently.

Considering the other options, while cloud storage and visual modeling tools are indeed essential aspects of application development, they do not align with the definition of a 'brew.' Similarly, while microflows are key components for implementing logic within an application, they serve a different purpose and are not synonymous with the concept of a brew. Thus, identifying a brew as a deployment unit highlights its role in the overall deployment and management lifecycle of Mendix applications.
