Where does marathon hand over execution to Mesos?

When you define and launch an application, Marathon hands over execution to Mesos. Mesos creates a sandbox directory for each task. The sandbox directory is a directory on each agent node that acts as an execution environment and contains relevant log files. The stderrand stdoutstreams are also written to the sandbox directory.

What is the definition of an application in Marathon?
