[PyWPS-dev] pywps in production on windows

[Idan Miara]

Hi Carsten, Luí­s and all,

Thanks for your replies!

Currently I use pywps with Docker based on gdal's official docker image
(which is ubuntu based).
https://github.com/talos-gis/talos_wps
The service is still under testing but so far it looks very promising.

I need to deploy it also on Windows because I need to use a customer's C
DLL which is Windows only, so either I will need to port the DLL to Linux
or find a way to run pywps on Windows in production.

Luí­s wrote to me that from what he read online, all Python classes dealing
with the Multiprocess must be modified to run on Windows, that is for
running it in an asynchronous mode.

I understand that this is not the normal setup, so I guess I will need to
test how suitable this demo.py
<https://github.com/bird-house/birdhouse-workshop/blob/master/demo/demo.py> is
for production on Windows, or look for some other solution.

Kind regards,
Idan
