Code & Log Storage Options

What options are available for code and log storage in an environment where orchestrator is NOT deployed? and where there is no source control repository (e.g. TFS).

Is anyone able to confirm which of the options below are available? And/or if there is a better alternative?

  1. Store code on local C: drive – Assuming this is ok
  2. Store code in database server – Unclear as to whether this is feasible if you are not using the orchestrator
  3. Store code on a shared drive – similar to option 1 but are we able to specify an alternative location for storing the code / logs rather than the default C drive
