A developer's application (app) is compiled and linked to a first processing environment associated with a cloud/server. Metadata is created to define the source code for the app, source code used with the app from the first processing environment, and settings for the app and the first processing environment. The metadata is stored on cloud/server location associated with a link. Optionally, the link is published to message threads/boards and/or a task of a workflow. A user of a mobile device provides the link/code within the context of a mobile app of the mobile device. The mobile app obtains the metadata using the link from the location and instantiates a container/shell that is provided the metadata. The container/shell configures as a self-contained instance of the developer's app within a second and self-contained processing environment and the self-contained instance is executed within a user interface window of the mobile app.
