Simulink model compilation on deployment (mcc and docker image)

Right now I am looking for the best way to deploy a simulink model as a standalone application which I can run multiple times in the cloud.

For now I have seen two possibilities of deployment:

• Create an .exe file using mcc
• Create a docker image of a matlab function running the model

I have based both solutions on the script given at Deploy with Simulink Compiler

When running the command to create the .exe file:

mcc -m deployedScript.m

I have seen in the command window that the model is being compiled:

### Building the rapid accelerator target for model: sldemo_suspn_3dof
### Successfully built the rapid accelerator target for model: sldemo_suspn_3dof

Build Summary

Top model rapid accelerator targets built:

Model              Action                       Rebuild Reason                 
===============================================================================
sldemo_suspn_3dof  Code generated and compiled  buildInfo.mat does not exist.  

Does this mean that the created executable contains a compiled copy of the model? or does the compilation happen each time that the application is executed?
